Terminal: Add a hyperlink mode When holding down Command, text under the mouse is checked whether it looks like a URL or a local path. If so, it is highlighted and can be clicked, which will open the URL/file. Right-clicking opens a context menu with items for opening the link/file or copying it to the clipboard. When additionally holding down Shift, path prefixes up to the component under the mouse will be considered (no effect for URLs). Changes: * Add HyperLink class. Encapsulates a type, the address, and an optional base address. Features an Open() method to open the address. * Move/add some string constants to TermConst. * Move TermView::CharClassifier to top level and rename to DefaultCharClassifier. * Introduce TermViewHighlight and TermViewHighlighter. The former refers to a range of text in a TermView's text buffer. It also contains a pointer to a TermViewHighlighter object, which specifies how the text range shall be rendered (colors and attributes). * TermView: - Add respective _{Add,Remove}Highlight() methods and adjust the code to support highlights. - Make the selection a TermViewHighlight. At least its visual aspect is now handled like other highlights. - Introduce an inner TextBufferSyncLocker. It is used instead of BAutolock when locking the text buffer to synchronize the visual buffer with it. After it unlocks it calls _VisibleTextBufferChanged(), if the visual text buffer has changed, which in turn calls a new callback on the active state. - Add WindowActivated() and ModifiersChanged() callbacks to the state interface. - Add new states HyperLinkState and HyperLinkMenuState which implement the new feature. Fix modifier issues

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. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25881 a95241bf-73f2-0310-859d-f6bbb57e9c96
