* The vm_translation_map is now correctly held in all of the vm_ mapping
functions.
* Removed the old vm_daemons.c file - there is now a new vm_daemons.cpp
which contains the beginnings of our new page daemon.
So far, it's pretty static and not much tested. What it currently does
is to rescan all pages in the system with a two-handed clock algorithm
and push pages into the modified and inactive lists.
* These inactive pages aren't really stolen yet, even though their mappings
are removed (ie. their next access will cause a page fault). This should
slow down Haiku a bit more, great, huh? :-)
* The page daemon currently only runs on low memory situations, though.

with those yet.

DEBUG_CACHE_LIST) that prints an unspectacular list of pointers to all
existing caches. Feel free to extend.
* Enhanced MultiAddressSpaceLocker:
- It supports choosing between read and write lock per address space,
now.
- Added AddAreaCacheAndLock(), which adds the address spaces of all
areas that are attached to a given area's cache, locks them, and
locks the cache. It makes sure that the area list didn't change in
the meantime and optionally also that all areas have their
no_cache_change flags cleared.
* Changed vm_copy_on_write_area() to take a cache instead of an area,
requiring it to be locked and all address spaces of affected areas to
be read-locked, plus all areas' no_cache_change flags to be cleared.
Callers simply use MultiAddressSpaceLocker:: AddAreaCacheAndLock() to
do that. This resolves an open TODO, that the areas' base, size, and
protection fields were accessed without their address spaces being
locked.
* vm_copy_area() does now always insert a cache for the target area. Not
doing that would cause source and target area being attached to
the same cache in case the target protection was read-only. This
would make them behave like cloned areas, which would lead to trouble
when one of the areas would be changed to writable later.
* Fixed the !writable -> writable case in vm_set_area_protection(). It
would simply change the protection of all mapped pages for this area,
including ones from lower caches, thus causing later writes to the
area to be seen by areas that shouldn't see them. This fixes a problem
with software breakpoints in gdb. They could cause other programs to
be dropped into the debugger.
* resize_area() uses MultiAddressSpaceLocker::AddAreaCacheAndLock() now,
too, and could be compacted quite a bit.

Condition variables would never be interrupted.
* ConditionVariableEntry::Add() did not correctly insert the entry into
the per-thread list of entries (the next link of the previous entry
was not adjusted), which could leave the entry unnotified when the
previous entry was notified, thus leaving it in the respective
condition variable's list after the end of its life time. This should
fix a crashing bug I rarely encountered.
* Added debug checks in the PrivateConditionVariableEntry
constructor/destructor that should have helped me to find
forementioned bug hours earlier, had I been bright enough to realize
that I didn't include <debug.h> and those KDEBUG guarded checks were
never executed. :-/

i386_reinit_user_debug_after_context_switch(), since I wonder every
time I see it. Should be optimized aways soon.

always put between window screens and modal all windows (before floating
all ones), so a BWindowScreen couldn't have menus at all.
Now, they behave more like floating app windows, just that they float above
all other application windows, such that all window feels (also BWindowScreen)
can now have menus.
* Reenabled keyboard redirection to the top most window in case it's a menu;
bug #1152 no longer applies due to the above change.

don't have a "db" command (we could probably add a small shell script
that invokes gdb in a Terminal), but just as BeOS we have
debug_thread(), which does exactly that -- throwing a thread into the
debugger. It (at least Haiku's version, not sure about BeOS's) also
interrupts system calls, which makes the semaphore releasing hack
superfluous.

needed, but now all reserved areas also grab a reference to their address
space.
* Rearranged team tear down to be a bit more sane: the I/O context is removed
first (where semaphores/areas/ports/whatever might still be used), and the
address space is deleted last.
* delete_area() can now remove its address space reference again (due to the
two changes above), and therefore fixes bug #1374.
* cleaned up vm_address_space.c a bit (no functional change there, though).

the real text. Also prevented stealing passwords via scripting (not
tested, though). Fixes bug #1354
Got rid of the _BTextGapBuffer_::[] operator since using it creates less readable code.
Also Implemented _BTextGapBuffer_::RealText() and used it instead of Text() inside BTextView. Will make sense later.

* moved separator in sending mode so grouping of trash icon is like in

though a custom menu field is needed to take care of invalidation)

* fixed follow mode of BMenuBar in fixed size mode (B_FOLLOW_LEFT_RIGHT)
* don't resize the BMenuField in fixed size mode (endless loop), this should
be more robust anyways, since this endless loop would be triggered if an
application tried to manually resize menuField->MenuBar() in auto resizing
mode
* fixed calculation of the parts that need to be redrawn on resize

* got rid of all the global variables (which were accessed completely without
locking, and the code with regards to the preference window sill needs
fixing)
* extracted some defines and helper functions to MailSupport.cpp, though I later
saw Utilities.cpp...
* got rid of the FONT_SIZE define which was used in some (but not all) controls
to override the system font size
* worked in Header.cpp to get the controls layout font sensitive with correct
alignment too, some problems remain when resizing the window
