Remove remaining unnecessary 'volatile' qualifiers

Fix Alternate/Normal screen's current attributes handling

Handle the current attributes of the TextBuffer consistently with other
Alt/Normal buffer sensitive variables. That fixes, for example, issues
with wrong background coloring of new lines in normal text buffer after
maximizing the terminal window running applications (like MC) performing
output onto alternate screen.

CodeStyle fixes, some refactoring and cleanup

* Clear some codestyle issues catched by checker script;
* Rename RestartDebugCapture to more consistent StartStopDebugCapture;
* Updated Copyrights and authors lists, some occurences of the raw MIT
licence text replaced with "under the terms of MIT licence" reference;
* Fixes for x86_64 build.

This is cumulative cleanup commit for series of Terminal refactoring
changes I have introduced last time. No significant functional changes.

Support Background Color Erase, switch to xterm-256color

* Lot of fixes to add support of BCE (background color erase). Shell
is switched to emulate xterm-256colors terminal, that is modern and
declare the colors capabilities of our Terminal more precisely;
* Move current character attributes fAttr from TermView to
BasicTerminalBuffer. This reduces count of function parameters on call
various InsertXXX routines;
* In alternative screen buffer mode the whole cells "matrix" of the
screen buffers is taken into account during drawing background of the
cells in the view. In normal mode the "attributes" field of the
TerminalLine is used to detect color of the area after the last
character - there should be no changes with previous behaviour;
* Fix attributes on kSpaceChar-padding short lines. Current _line_
attributes should be used instead of current _global_ attributes;
* Fixed pads and gaps attributes, more accurate handling of ESC[K and K°;
* _Invalidate strings just erased. Fix EraseChars DCH processing;
* Fixes for ESC[J erase lines control sequences;
* Added handling SGR 90-97, 100-107 codes;
* Clean the newly allocated TerminalLine lines;
* More precise cursor background [off-]color estimation at ends of
lines. The current line attributes should be used instead of
hard-coding it to fTextBackground;
* Fixed background color erase in normal screen buffer modes. Wrong
line indexes calculation messed the drawing results or just returned
0 [default] line attributes;
* Some more BCE support: TerminalLine::Clear() now honors current
character attributes;
* Fixes #6143, #6510 and #6424.

OSC and color management improoved

* Global kTermColorTable replaced with it's private copy for every
TermView instance. This allows to modify colors table for every view
separately;
* Set of ANSI normal/bright color entries added into preferences;
* Default color table generated dynamicaly using ANSI colors
preferences. 6x6x6 color cubes and grayscale ramp are generated in
xterm colors model;
* Improoved support of Operating System Command control sequences;
* Support for X11 rgb.txt compatible color names. Corresponding entries
are stored in hashed form in application resource and loaded only on
demand.

Refactoring of 8-bit encodings support.
* Fixed issue introduced in hrev38139: restoring from the line
drawing table was hard-coded to UTF8 Ground table. That is wrong:
the table for currently configured encoding must be set back.
Please look on using of _GuessGroundTable() for details;

* Fixed issue introduced in hrev34894: the semantic of convert_xx_utf8
functions requires the destination length to be set equal to the
target buffer size. Pre-hrev34894 usage of "homebrew" conversion
functions was a bit different - destination length was set to 0.
This made any converstions of input data useless and produce no
visual results;

* Private list of supported encodings (Encoding.cpp) was replaced by
using BPrivate::BCharacterSetRoster functionality. That allows to
use centralized info about encodings in unified with other
applications (Mail & StyledEdit for example) way. Most of currently
enumerated in UTF8.h encodings now available in Terminal.
Note that UCS-2 and UTF-16 are temporary (???) excluded from the
list of encodings supported by Terminal.

* The B_UTF16_CONVERSION was added in system-wide UTF8.h declarations.
This character set is available for enumerating by BCharacterSetRoster
but not listed in public API. Looks like it was just missed;

* Special note about "Text Encoding" entry in Preference File:
So known "shortname" of encoding was used in the preferences file.
For details look on the encodings list in previous version of
Encoding.cpp. As result of migrating to BCharacterSet-provided
resources this list was deleted and is not available anymore.
Instead of it the IANA name of the character encoding targeted
to be used for this purposes. Frankly speaking this part looks
like not working at the moment. The value of text encoding is
hardcoded to "UTF-8" now and is not affected by any operations
in Terminal menu. Note that "shortname" for default encoding
was "UTF8" but the saved value is "UTF-8" - and they are looking
not dependent at all. So this change should not introduce any
kind of backward incompatibility.

mmlr+anevilyak:
Unconditionally release the reader sem when the previous buffer size was 0
instead of testing for fParserWaiting as there is a race condition between
setting it to true in the parser thread and checking for it in the reader
thread so a release_sem() could be missed causing #4343. To reduce the possible
side effect of needlessly looping through acquire_sem() for too many
unconditionally released sems, we eat them in the parser thread once we're sure
we can't miss an event because of that. Also added a TODO about a memcpy()
optimization as pointed out by Rene.

* Implemented alternate screen buffer support. Not used by any program
yet, since we still use the beterm termcap entry.

* Renamed GetReaderBuf() to _NextParseChar().
* Introduced a small (64 byte) buffer for the parser thread. Instead of
directly reading single characters out of the reader buffer, we read
a full parser buffer and process the characters from the parser
buffer. Thus _NextParseChar() could be inlined, since it merely
consists of a conditional method call and an access to the parser
buffer, now.
* Improved the locking of the terminal buffer. Instead of unlocking and
relocking after every multi-byte char or escape sequence, we only
unlock while refilling the parser buffer.

Changed the way the pty reader and output parser thread communicate. The
parser was acquiring a semaphore for each character. Now it only
acquires a semaphore when the buffer is empty. This speeds up output
bound programs. In my setup "seq" is now 3 times faster. Which is still
rather slow.

Terminal changes. This is still work in progress, some features
are disabled, lots of commented debug code is still in there,
and quite a bit of cleanup is needed, but basically things work
at least as well as before with several improvements:
* Changed TerminalBuffer from an interface to a complete
implementation. Removed all related code from TermView. Removed
the now obsolete TermBuffer. TermParse uses TerminalBuffer instead
of TermView, and TerminalBuffer asynchronously notifies TermView.
This avoids potential deadlocks, fixing #1918. It also speeds
up tty-output-bound programs. E.g. a "seq 10000" is about twice
at fast with the default terminal size in my setup, now. It's
still horribly slow compared to e.g. Konsole, though.
* Replaced CurPos by a more compact and fully inline class TermPos.
* Removed the offset feature (that insets the used text area) from
TermView, thus simplifying the code. Instead put the view into a
new parent view which provides the insets. This also fixes
artifacts that could sometimes be observed in the insets area.
* Scrolling related changes:
- When scrolling fully down, the (80x25 or whatever) terminal
screen is seen. It is not possible to scroll below the screen as
in Be's Terminal. Scrolling in Haiku's Terminal was weirdly
broken in this respect. As a side effect this fixes #2070.
- When not scrolled fully down, further output won't cause any
scrolling. It is thus possible to read earlier output while
something is still going on. Fixes #1772.
- Particularly to avoid unnecessary scrolling in the not scrolled
fully down case, TermView no longer actually scrolls. It only
sets an internal offset and manually uses CopyBits() as needed.
Introduced a (hacky) BScrollView subclass using a BScrollBar
subclass to make that possible.
* Selection related changes:
- Double/triple click plus dragging allows for selecting multiple
words/lines.
- Word selection no longer selects ranges of non-space characters.
Instead it knows that words are made of alpha numerical chars and
a certain set of other chars, and selects a range of commonly
classified characters (word chars, non-word non-whitespace chars,
whitespace chars). The non-alpha-num word characters should be
made user-settable. Due to missing multi-byte character
classification multi-byte whitespace is not recognized.
- Beyond the end of the line there no longer are invisible spaces.
Trying to select the region selects the end of the line (i.e.
line break). This is similar to how Konsole and xterm work.
- Added auto-scrolling when selecting with the mouse. Formerly the
Terminal scrolled only while moving the mouse. The scroll speed
might need some fine-tuning.
- Don't know what change exactly did that (likely the switch to
non-end-inclusive text ranges used internally), but the
occasional selection artifacts are gone.
* Resizing the terminal window re-wraps soft-wrapped lines.
* The find functionality seemed to be completely broken. At least it
never found anything for me. Should work now, though multi-byte
characters are not matched correctly in case-insensitive mode.

Regressions:
* Printing is disabled.
* Cursor blinking is disabled. Do we want it anyway?
* In several cases full-width characters are not handled correctly
(in more cases than before).
* Shrinking the terminal width doesn't work very well with "less"
(and probably other full-screen terminal apps), due to line
re-wrapping. "less" expects them to be truncated only. When
supporting an alternate screen buffer re-wrapping should be
disabled for it, which should solve the problem.

Pulled the TermView interface used by TermParse into a new interface
class TerminalBuffer, which will evolve into a TermBuffer replacement
and decouple the parse thread from the window.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21762 a95241bf-73f2-0310-859d-f6bbb57e9c96

Moved cursor blinking functionality from TermParse into TermView (and
from a BMessageRunner into Pulse()). Removed more unused stuff.
Moved around some constants and definitions. Many style changes. Sorry,
I know the two should be separated, but I had already done so many changes...


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21695 a95241bf-73f2-0310-859d-f6bbb57e9c96

Made all CodeConv methods static, since there was no point for them to
be nonstatic. Moved TermParse under Shell, Removed some parameters
passing around from TermWindow/TermView/TermParse. Now TermParse threads are
started when the shell is attached to a TermView. Might still be
improved.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21680 a95241bf-73f2-0310-859d-f6bbb57e9c96

Encapsulated low level terminal stuff into a Shell class, which also
supersedes spawn_shell(). Removed window parameter from TermParse. Since
we already have a pointer to the view, we just call Window() on it (only
used in one place, no need to save a pointer). Other cleanups.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21628 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Rewrote terminal ID code to use a temporary file - this fixes bug #1174.
* Tried to fix the usual deadlock on quit, but suspending the thread (to
interrupt read()) doesn't have the expected outcome (might be a kernel
bug).
* Removed superfluous MENU_FILE_QUIT and send a B_QUIT_REQUESTED instead.
* Cleanup.

cleaned up a bit thread creation and deletion

Moved cursor blinking functionality from TermParse into TermView (and
from a BMessageRunner into Pulse()). Removed more unused stuff.
Moved around some constants and definitions. Many style changes. Sorry,
I know the two should be separated, but I had already done so many changes...

Made all CodeConv methods static, since there was no point for them to
be nonstatic. Moved TermParse under Shell, Removed some parameters
passing around from TermWindow/TermView/TermParse. Now TermParse threads are
started when the shell is attached to a TermView. Might still be
improved.

Encapsulated low level terminal stuff into a Shell class, which also
supersedes spawn_shell(). Removed window parameter from TermParse. Since
we already have a pointer to the view, we just call Window() on it (only
used in one place, no need to save a pointer). Other cleanups.

* Rewrote terminal ID code to use a temporary file - this fixes bug #1174.
* Tried to fix the usual deadlock on quit, but suspending the thread (to
interrupt read()) doesn't have the expected outcome (might be a kernel
bug).
* Removed superfluous MENU_FILE_QUIT and send a B_QUIT_REQUESTED instead.
* Cleanup.

Got rid of the global gPfd variable. Big time cleanup, made TermParse a
bit more robust with error checks and likes. Removed unused
TermPrint.cpp file. I hope I didn't get on your
way, Vasilis :)

Moved the files out of the MYOB folder into the main folder.
There are some double entries (like TermApp.cpp and TerminalApp.cpp, so
it still needs a further cleanup).
