be better (thread safe).

most fitting size. This fixes#597

BIOS owned flag and clear all possibly enabled SMIs. It seems to be common
practice to just ignore this error case, probably because there are enough
broken BIOSs out there that do not correctly hand over the controller.

BasicTerminalBuffer. It synchronizes this buffer with the actual
terminal buffer and uses it for drawing. This does significantly
decrease the time the terminal buffer is locked by the window thread,
and avoids the necessity to do invalidations in Draw() when the
terminal buffer changed in the meantime.
* When the view detects heavy scrolling of the terminal buffer due to
lots of continued output, it throttles redraws to one every 0.1s. The
detection condition might need some fine-tuning -- it's probably a bit
too strict for most situations.
I guess I'm done now with optimizations. After testing on real iron for
the first time, I'm a little impressed. In the "time seq ..." speed
competition Haiku's Terminal easily beats Konsole by 10 to 20% for 80x25
and by factor 3+ for full screen. And if I interpret the results
correctly 90% of the time is actually used by "seq" itself which seems
to be about 5 times slower than under Linux.

we now double/halve the current size of the list, starting with the constructor blocksize as a baseline.
This has the net effect that when doing large numbers of inserts/removes, the number of resize operations
needed scales logarithmically to the number of operations, which should yield a decent performance
improvement in such cases.
Review welcome. This does not yet affect ticket #2363 that I'm aware of, as I'm currently in the process
of attempting to find a copy of said app to test with.

handover indeed worked. Doesn't really matter though, as we reset anyway,
just not twice in the success case.
* Disable all interrupts and clear any pending active interrupts just after
taking over the controller. This might fix bug #2361.
* Also trace output when the ownership change is successful.
* Don't disable interrupts during reset.

* Added a ResizeTo() version that allows to set the history capacity at
the same time.
* Added a SynchronizeWith() method that allows synchronizing with (a
part of) another buffer.
* Fixed TODO in _Scroll().
* Improved the dirty region update code in _Scroll(). It would in
certain (not exactly uncommon) situations needlessly invalidate the
whole screen.

* 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.

always Bounds() now.
This fixes#361, again we're better than R5! Although in this test case, the scrollbars shouldn't be activated in the first place. In icon mode the poseview is still putting too much white space on
the left (x<0) and make the scrollbars show. Fix is almost ready :-)

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.

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.
