wm4 9b121dfc32 w32pthreads: always use Vista+ API, drop XP support
This removes the XP compatibility code, and switches entirely to SWR
locks, which are available starting at Windows Vista.

This removes CRITICAL_SECTION use, which allows us to add
PTHREAD_MUTEX_INITIALIZER, which will be useful later.

Windows XP is hereby not a supported build target anymore. It was
decided in a project vote that this is OK.

Muhammad Faiz a3d3cfa65c avutil: merge slice threading implementation from avcodec and avfilter
Rework it to improve performance. Now mutex is not shared by workers,
instead each worker has its own mutex and condition variable. This
reduces lock contention between workers. Also use atomic variable for
counter.

The interface also allows execute to run special function on main
thread, requested by Ronald.
