Previously long URI/URLs (> 1024 characters) would cause a stack corruption and crash Wine. After this MR, Wine will no longer crash but the URL is not opened either primarily due to `SHELL_Argify` limitations.

v3: shell32: Increase timeout for long URLs

Using a dedicated exit jmpbuf and removing the need for assembly
routines.
When Wine handles an exception in unix code, we return to user mode by
jumping to the last syscall frame. This can leave some pthread cancel
cleanups registered, in the pthread internal linked list, and at the
same time later overwrite the stack frame they were registered for.
In the same way, jumping to the exit frame on thread exit or abort, can
also leave some cleanup handlers registered for invalid stack frames.
Depending on the implementation, calling pthread_exit will cause all the
registered pthread cleanup handlers to be called, possibly jumping back
to now overwritten stack frames and causing segmentation faults.
Exiting a pthread normally, by returning from its procedure, or calling
exit(0) for the main thread doesn't run pthread_exit and doesn't call
cleanup handlers, avoiding that situation.

### Additional note:
For robustness, we should probably try to execute these cleanup handlers
when unwinding the stack frames, as we would otherwise leave pthread
objects in a potential problematic state (like a mutex locked, etc).
It is however hard to do so when the handlers are registered from some C
code: pthread C implementation is done by calling some internal pthread
functions to register the handlers, and they aren't registered as
standard unwind handlers.
Only pthread_cancel and pthread_exit can unwind and call / unregister
the C handlers, but interrupting that procedure, for instance calling
setjmp / longjmp from withing our own handler isn't supported.
From C++ code, pthread cleanup handlers are registered through C++ class
constructors / destructors, and it would then be possible to partially
unwind and call them at the same time.

Windows gives this content special protection from being painted over, by some means that I have not investigated yet.
Emulate this protection for the trivial case of an InvalidateRect(...); call on the parent window.

This avoids stalling the pipeline when upstream nodes have not given enough samples for processing. If there are multiple upstream nodes, request samples in a round-robin fashion.
This fixes an issue where the intro audio of the game Airborne Kingdom stops playing after a few seconds.
