This reverts hrev54120 and instead adds the commonly supported
MAP_NORESERVE flag to request overcommit.
Using PROT_NONE for overcommit is problematic as the protection of
individual pages can still be changed via mprotect to make them
accessible, but that won't change the commitment. An application
using such a pattern may then unexpectedly run into out of memory
conditions on random writes into the address space.
With MAP_NORESERVE the overcommit can explicitly be requested by
applications that want to reserve address space without producing
memory pressure.

Rename MovePageRange to Adopt and group it with Resize/Rebase as it
covers the third, middle cut case.
Implement VMAnonymousCache::Adopt() to actually adopt swap pages. This
has to recreate swap blocks instead of taking them over from the source
cache as the cut offset or base offset between the caches may not be
swap block aligned. This means that adoption may fail due to memory
shortage in allocating the swap blocks.
For the middle cut case it is therefore now possible to have the adopt
fail in which case the previous cache restore logic is applied. Since
the readoption of the pages from the second cache can fail for the same
reason, there is a slight chance that we can't restore and lose pages.
For now, just panic in such a case and add a TODO to free memory and
retry.

This code comes from an old Be Newsletter and since then the API
received the addition of SetMouseEventMask. In several places the
MouseDownThread was misused: it would spawn a new thread on every mouse
click and not clear the previous one. This could for example lead to
BSpinner skipping values if you clicked it at the right speed.
There are functional changes in BSpinner, before it updated for the
first time 100ms after mouse down, and then as you moved the mouse
around the button, now it activates immediately on first click and then
every 200ms (which may be a bit short). In other places, no functional
changes intended.

it seems #14963 occurs. So perhaps there is a GCC bug

It was not specified as such before C11, but that's only because there

BeOS didn't support transparent views. As documented in the Be Book,
SetViewColor(B_TRANSPARENT_COLOR) only effect is to not fill the
invalidated areas with the view color before calling Draw() (it avoids
flickering, especially when combined with B_FULL_UPDATE_ON_RESIZE).
A previous change made B_TRANSPARENT_COLOR actually make the view
transparent (that is, additionally to the above, the underlying view is
drawn before the transparent children), but it creates compatibility
issues.
In order to keep the API compatible with BeOS, the new behavior is now
enabled explicitly using the B_TRANSPARENT_VIEW flag. This also opens
for future developments like allowing a view color with an alpha
channel (not supported yet).
Adjust programs that require transparent views.

Scroll bars should look and work identically to before on
HaikuControlLook.
Add DrawScrollBarButton() and DrawScrollBarThumb() and
DrawScrollBarBorder() methods. These methods are used to draw scroll
bars in a generic way so that they can be drawn differently by alternative
control look's (e.g. BeControlLook). Also it gives us back drawing of
scroll bar knobs. However the knob setting is not exposed in the
interface in this commit.
These methods are in addition to the 2 existing DrawScrollBarBackground()
methods that draw the scroll bar background. One draws the area above and
below the thumb and the other is called by the first to actually draw the
area.
The rest of the drawing besides the backgrounds was being done in
BScrollBar before. To draw the scroll bar arrows and thumb we were recyling
other ControlLook methods, while this worked well enough on HaikuControlLook
it wasn't flexible enough for alternative control looks.
DrawScrollBarButton() is used to draw the four scroll buttons and is
typically (so far) used in combination with DrawArrowShape().
DrawScrollBarThumb() draws the scroll bar thumb.
DrawScrollBarBorder() draws a 1px border around the entire scroll bar,
potentially B_KEYBOARD_NAVIGATION_COLOR if focused (although this is
feature not currently used.)
Draw unscrollable scroll bars as if they were disabled including the
buttons with their arrow shapes, background, and thumb.
Add FBC backwords compatibility macros in ControlLook.cpp
