the delta.
For example, MoveBy(-0.5, 0.0) would do nothing in this case:
roundf(150.0 - 0.5) = 150.0, when rounding the delta it gives the
expected value: roundf(150.0 + roundf(-0.5)) = 149.
On the other hand, BView::ResizeBy was doing it right, and this
explains the bug in Cortex (#333). Cortex was doing
scrollBar->MoveBy(-0.5,0) then scrollBar->ResizeBy(0.5,0) and the
inconsistency lead to the visual bug. (see StatusView::MouseMoved())
This fixes#333. The bug was strange to reproduce since sometimes the
point received in MouseMoved would be "some_integer+0.5" values
sometimes just integral. This has still to be investigated though not
problematic here anymore. See cortex/RouteApp/StatusView.cpp line 222.

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.

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.
