Terminal: Handle SIGCHLD in a dedicated thread

Block SIGCHLD in all threads and spawn a dedicated thread that handles
the signal in a loop (via sigwait()). This avoids the issue that the
SIGCHLD could be handled in any of our threads and thus possibly
interrupt a syscall.

Fixes #10941.

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.

Move colors table from TermView to TerminalBuffer

* ColorsTable moved to TerminalBuffer to let easy lookup of table
during parsing of control sequences;
* Default Palette initialized from now in TermApp and preserved
from modifying by applications;

Removal of the About window.

* Added new class TerminalRoster, which maintains a list of all running
terminals, including their window minimized status and workspaces. These
information are shared via our special-purpose clipboard. TerminalRoster
mainly acts as a cache.
* Removed the terminal ID management from TermApp. Most is now done by
TerminalRoster, the rest has been moved to TermWindow.
* Moved the terminal position file reading/writing from TermApp to TermWindow.
* Moved the remaining terminal window title handling from TermApp to TermWindow.
* Replaced the solution for #6613 implemented in r39530 (enabling/disabling the
"Switch Terminals" menu item depending on whether there are other Terminals).
The new solution is more correct, since it does enable the menu item, if and
only if switching to another Terminal will happen when triggering it. I.e.
minimized Terminals and ones on other workspaces are ignored.

Should also fix #6612, since there's no synchronous communication between
different terminal apps anymore.

Implemented support for dynamic tab and window titles:
* Added settings for tab and window titles. Both are strings with optional
placeholders for tab/terminal index, currently active process name and
current directory.
* Added a generic utility class PatternEvaluator that allows to expand this
kind of pattern strings and callback classes
[Tab,Window]TitlePlaceholderMapper that provide the specific expansion for
the tab and window title placeholders.
* TermWindow:
- Separated the notions of session (== tab) and window titles. The tty
clients no longer set the window, but the session title.
- Use the patterns instead of the hard-coded window/tab titles.
- Recompute all titles once a second, so changes of running programs are
reflected.
* The default patterns for tab and window titles are "%1d: %p" (last CWD
component and name of the running process) and "Terminal %i: %t" (Terminal
ID and active tab title). Unfortunately the space on the tabs is seriously
limited, so that the tab title is virtually always truncated. Ideas welcome.

Override BApplication::QuitRequested(), so that when the system is shutting
down, we can skip the checks for running processes. At least I found the
alerts seriously annoying in this case.

Patch by rossi, but I ended u rewriting half of it :
* Save terminal windows positions
* Also save their size and workspace, but these aren't used (size is overriden by the menu setting and workspace is annoying)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38192 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Update all applications in tree to use the new localizing system
* Remove the old one from the locale librairy, with some cleanup
Known regressions :
* readonlybootprompt will no longer update the locale settings : the
method used messed with internal undocumented things
* external localized apps (webpositive for example) will not run
anymore.

* When switching Terminals via Command-G, we now also take the workspace
information into account, ie. we now behave like the Terminal on BeOS, and only
allow to switch between the Terminal windows of one workspace.

Added a SIGCHLD handler, so that the terminal will notice when one of
its shells has been terminated. Usually the thread reading from the tty
master would notice when all slaves have been closed, but they won't be
closed when the shell started a background job that's still living.

Unfortunately there are race conditions in the terminal that can lead to
deadlock when a session is closed. The service threads usually happily
lock the window, while the (locked) window would wait for the service
threads to quit.

Stolen Ingo's Arguments class from Miniterminal and used it in place of
GPL'd code in TermApp (slightly modified, and bugfixed, even :P).
TermView now accepts an argument vector instead of a commandline. Same
thing for Shell.
Temporarily(?) removed some commandline options.
This also fixes bug #1396 (tested)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21979 a95241bf-73f2-0310-859d-f6bbb57e9c96

Moved all TermView initializing code into TermView itself. Before you
couldn't just rely on its constructor to fully initialize the object,
since the code was scattered around, mostly into TermWindow. Added a
commented out TermWindow constructor which only creates and adds a
TermView object to the view hierarchy, which now works.
Removed weird TermWindowActivate method, use WindowActivated
instead. TermApp can now keep a pointer to a BWindow instead of
TermWindow, since it doesn't do anything special with it.
TermView::SetTermFont() now can filter the font attributes (it uses
B_FIXED_SPACING, I'm not sure it's needed but it doesn't hurt). Usual
cleanups.

global functions (at least for now), removed useless globals, restyled
the code. Not yet done.

* Implemented the Terminal-ID search using a BClipboard and the new atomicity
feature of BClipboard::Commit().
* The file based version is now only used when the Terminal is built for BeOS.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20941 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.

* Setting the window title via "-t" now works.
* Improved error message in case the initial shell couldn't be executed.
* Disabled setting the colors via arguments, mostly because it just did quit
the app in case there were any arguments and no /etc/rgb.txt file. This
allows Terminal to be used by the debug_server instead of MiniTerminal.

Removed the ugly about window, and replaced it with a common BAlert.
Moved the alert to TermApp, too - TermWindow now only forwards the B_ABOUT_REQUESTED message.

There are some double entries (like TermApp.cpp and TerminalApp.cpp, so
it still needs a further cleanup).
