d1adf9e8d6 Allow skipping functions on top of call stack.
Note that this is on-client performance intensive and shouldn't be used,
except in special situations, like processing crashes.

b371003336 In case of manual shutdown, don't wait for lock.
All threads are freezed at this point, nothing will release it.

401ebd6f3d Use spin-lock in DequeueSerial.
A thread freezed during crash processing may hold the lock and never
release it. The old behavior would cause deadlock in such situation. The
new one can be modified to work. Also, we don't want to use timed mutex.

0258f4a7b4 Handle crashes on windows.
When a crash happens, put all threads (bar the profiler and crash
handling ones) into the freezer, send crash notification message,
request profiler shutdown and when it does, terminate process.

The list of ignored exceptions is sorta-kinda random at the moment and
may need further expansion.
