We do not know anything about the symbols we are being asked to demangle;
it is entirely possible they are malformed, or that we parse them incorrectly,
which previously led to buffer overflows. E.g. the "2","8" in "SetTo__Q28_GLOBAL_"
is presently incorrectly parsed as a length, leading to an access 21 bytes past
the end of the string.
This caused a page fault under the guarded heap, a fact I had the misfortune
to discover when trying to attach Debugger to a guarded-heap'd application
which somehow ran the demangler under the guarded heap also, and that symbol
above was in runtime_loader, so it crashed while loading its symbols.
So now we do what the GCC3+ demangler does here, and keep track of the input
buffer through the use of a state class, which will prevent us from incrementing
past the buffer's end.
I've tested this patch using the new haikuc++filt utility against libtracker
(indeed, it took multiple rounds of testing to get the diff to be 0 bytes)
and it seems to work exactly as before, though now without out-of-bounds
accesses.
As this demangler is also used in the kernel, it's possible that some
triple-faults on x86_gcc2[h] are caused by this bug (although that would
be rare; one of the incorrectly-parsed symbols would have to be in the
stack trace, and then it would have to read past the end of the buffer
containing the symbol.)

Built as "haikuc++filt" so you can keep it in PATH without replacing GCC's.
The implementation is a very close copy of "demumble", which is
under the Apache 2 license, so this is also. Most of the modifications
to "demumble" were to strip out Windows symbol support, and then
add GCC2 symbol support (this required reworking of the main loop,
as we detect GCC2 symbols in a different way than Itanium symbols.)
I've also added a command-line flag to ignore GCC2 symbols when stream-
processing, which is sometimes useful when demangling GCC3+ symbols.
Running this under guarded heap with some random SOs shows that there are
some symbols which apparently cause memory corruption in the GCC2 demangler.
I haven't yet looked into that, though.
They may still be running at the point we detach from the window, and
as we stop watching everything else at that point (and the threads
themselves depend on the window looper as the global "lock"), we
need to tear them down then.
We especially cannot do this in the destructor, as there are some
virtual methods that the threads need during their teardown which
obviously will not work in ~BPoseView.
Fixes#13371, and potentially other Tracker crashes that occured
as a result of closing the window while the add-poses tasks were
still operational.

When HEAD is tagged, the output will be identical to what it was
before (the latest hrev tag and nothing else.) When HEAD is not tagged,
and the most recent tag is further back, we now use a format like this:
hrevXXXXX+N(+dirty)
... where N is the number of commits since hrevXXXXX, and +dirty is added
if the working tree is dirty. This is significantly shorter than the
previous model (as it does not have the Git revision.)

The action vm_page_fault takes should depend on whether the iframe to be
handled is a user iframe or not. The check for the user flag in the
error code does however only check if the fault happend in user or
kernel space. Use IFRAME_IS_USER() instead which checks the privilege
level of the iframe. Under 32 bit x86 this also handles vm86
compatibility mode properly.
This is the same logic as used on FreeBSD (TRAPF_USERMODE).

all of the BMenuItems and then closes the menu, which crashes,
as the BMenuItems do not notify the BMenu they are being deleted.
I tested this on BeOS and it seems that this model crashes there also
(looking through the code comments, it seems there are a number of
testcases found throughout the years like this.) Removing the items
before deleting them indeed fixes the crashes on both BeOS

...if the row is present in the list, but continue to return false if the

Part of #11675. Cherry-picked from https://review.haiku-os.org/442.
BFS does this as part of journal management, but not as part of block
cache synchronization (which makes sense, as flushing it then would
defeat the purpose of the drive's write cache.) No other file system
seems to touch it at all, so we should do it as part of an explicit sync.
This may help with some of the filesystem corruption issues, as it seems
that on slow disks, the drive might not have enough time to flush the cache
before it is powered off (or on some SATA/AHCI based disks, it is not flushed
before close at all), so triggering it here and, as the ioctl is supposed to be
synchronous, waiting for it also, seems to make sense.

Here's what happens:
* BPackageManager created a BRefreshRepositoryRequest with a BContext
of an empty DecisionProvider and itself.
* Since there is no internet access, the FetchFileJobs that the refresh
class queued fail. Specifically, the first one does, but then as the
subsequent ones depend on it, they are all aborted.
* As some jobs were aborted, the StateListener is notified.
* The state listener of course has the BPackageManager class as one of
the listeners, and so calls it, because even though the handler methods
of BRefreshRepositoryRequest, they are powerless to stop event propagation.
* The BPackageManager's highest subclass' implementation gets called, which is
of course pkgman's.
* pkgman decides to DIE() upon receiving word that a job was aborted.
There are thus four potential solutions to this issue:
* Rewrite the package kit's event & job handling systems to not be so
screwed up in terms of propagation. Seriously, there is way too much
stuff that we send to the "user" in here, and as you can see, it can
get *extremely* convoluted even for supposedly "simple" tasks. This
is probably the best "long-term" solution; but obviously is far too
involved for the present.
* Only partially rework event handling; specifically in the SupportKit to
allow JobStateListeners to stop further propagation. This is probably
the best "medium-term" solution.
* Do not pass the package manager as the JobStateListener to the
RefreshRepositoryRequest. This would have the downside that the
regular notifications about download state, etc. would not be returned
at all, which we don't want. We could make a shim ... but that would be
a lot of code for little benefit. The prior solution makes more sense.
* Completely ignore "JobAborted" notices in pkgman. In fact, this is the
solution that virtually all other consumers of this API take (although
some of them seem to have TODOs about it), including package_daemon,
HaikuDepot, etc., and so it's the one I've taken here. If a "job aborted"
error is actually fatal, then it's the Package Kit's problem.

"Elementary streams" were introduced with MPEG-2, but did not find much use
outside of internal data interchange until now, which finds some HEVC
files being actually distributed in this format.
The first four bytes (00 00 00 01) are common to all (packetized?) elementary
streams, while the three following (40 01 0c) identify a HEVC stream. Actually
I could not find good data on these; all the HEVC files I saw (and some hex-
dumps on online mailing lists of more) contain these three bytes in common
while following ones appear to be the internal header. (I didn't dig deeply
enough into FFmpeg's source code to find out the "real deal.")
