Custom background image is disallowed on the Desktop folder and Root
aka "Disks" folder. However, you may use a default background image.
We store the background image on the node, Desktop window and the
actual Desktop share the same node so we have to explicitly disallow
background images from showing on Desktop windows.
Make UpdateBackgroundImage() protected.
Remove unused BDeskWindow::UpdateDesktopBackgroundImages();
Handle all background image code in ContainerWindow. BPoseView calls
its window if targetted to update its background image.
Fixes Desktop background portion of #19947.

It seems in some applications (though not most of the ones I
initially tested) this can get used recursively, so we need
a recursive_lock in order to not deadlock.
Also commit a missed change from the previous commit.
X512 pointed out that ServerLink is inherited by PortLink which is
used by all windows, so the original change had the unintended effect
of allocating another semaphore for every window, which isn't wanted.
So, just use a static mutex here also.

Fallback to DBG2 if SPCR is not present while discovering UART serial

This has only been tested in Hyper-V which exposes DBG2.

The case where no BApplication has been created at the time of fork
is not blocked by this change (as it might be useful in fork-to-background
before creating a BApplication.)
Reinitializing or recreating a BApplication where one already exists,
though, is not supported by the kits, and just leads to problems.
And when the global destructors are invoked after a fork, such as by
exit(), then the parent team's state may be corrupted due to the
deletion of BLocker semaphores or other global state.
So, we thus set be_app to an invalid pointer, and if terminate_after()
is called with this pointer, we invoke debugger().
(We should really just prevent semaphores from being used across
processes unless explicitly specified, but that would be an
API compatibility break from BeOS, so we'll need to do it carefully,
or not until after R1.)
Would have clearly caught the problem in #18576 and the linked thread.
They don't work properly after a fork, and if exit() is called
from the forked child, the parent won't be able to use them
anymore.
In BBitmap and BPicture, replace them with mutexes. For AppServerLink,
make the private ServerLink inherit from BLocker, and then use
that one directly.
This also is a slight efficiency gain, as we don't need to create
multiple semaphores from the static initializers now, which is
just a waste of time in the case of applications that don't
even need these locks but link to libbe.so (e.g. CLI tools.)
Part of #18576.
This now does what notify_if_stat_changed used to, fixing a
race: if some thread was modifying a file, and some other thread
(or the same thread, in some other mtime-updating operation)
updated that file and this called MarkUnmodified() before the
first thread close()d it, then when the first thread called close(),
no node monitor notification would've been sent, as fModified
would've already been unset.
So, now every time we are to mark a file "unmodified", we also
send the node monitor notification at the same time.
Fixes the remainder of #19910.
This reverts commit 902921a554.
This broke resolution of CNAMEs, including the Haiku package repos.
Since pkgman uses our own HTTP implementation, which doesn't set
AI_V4MAPPED at all, this shouldn't have been a behavioral change for
it at all, much less having broken it.

If a context switch happened between the messsage being
sent and received, we don't need to invalidate.
Brief testing on a 4-core VM shows this happens relatively
rarely during compile jobs (expected, most processes are
single-threaded), but very often while running multiprocess
web browsers. Some INVALIDATE_PAGES are skipped, but mostly
INVALIDATE_PAGE_LIST is (by the thousands.)

This way we don't need to call barrier_unlock() in every thread
after exiting the wait loop, some syscalls. We can also avoid
spinning on the barrier mutex in "ensure_idle" (which is renamed
"ensure_none_exiting" for clarity), and instead lock it once and wait
for some thread to unblock all.
Overall, this strategy appears to be as much as 25% faster
than the previous, testing with pthread_barrier_test.
It seems the old design had at least one possible but very narrow
race in the "last one out" logic: if that thread was suspended
between the atomic_add() and the assignment of barrier->lock, and
all three other threads then ran past the add() in the next run,
then when the last-one-out woke up, it would clear the WAITING
flag spuriously.
This may help with #19876.
The runtime_loader previously used resize_area without properly
