now, if the process group changes.
* Added another TODO: setpgid() is supposed to fail on a child after
it has executed exec*().

HaikuImage and enabled individually using the
AddOptionalHaikuImagePackages rule or all at once by setting
HAIKU_ADD_ALL_OPTIONAL_PACKAGES. In principle an optional package can
be any kind of addition to the Haiku image, but usually a zip file will
be downloaded from somewhere and unzipped onto the image. I've added a
WonderBrush package as an example.

* Unfortunately it's not allowed to set user xattrs on symlinks. So, if
we've failed in fs_write_attr() to set an extended attribute, we check
whether the node is a symlink and the attribute just a "BEOS:TYPE",
and pretend to have succeeded in this case. Thus we avoid annoying
error messages e.g. in unzip.

attributes with those names.

xattrs from other programs (e.g. Beagle) to end up on the image.

* 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. :-/

Can be enabled by defining KERNEL_BREAKPOINTS in arch/user_debugger.h

function. Hitting a break-/watchpoint will throw the thread into KDL.

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.
