2017-12-26w32pthreads: always use Vista+ API, drop XP supportwm4
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.

2017-07-19avcodec/pthread_slice: use slice threading from avutilMuhammad Faiz
Also remove pthread_cond_broadcast(progress_cond) on uninit. Broadcasting it is not required because workers are always parked when they are not in thread_execute. So it is imposible that a worker is waiting on progress_cond when uninitialized.

2015-02-24lavc/pthread_slice: release entriesChristophe Gisquet
When calling ff_alloc_entries, a number of entries are created. They are never freed, as running fate with slice threading and several frames on e.g. fate-hevc-conformance-ENTP_A_Qualcomm_1 would show. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

2013-11-04pthread: store thread contexts in AVCodecInternal instead of AVCodecContextAnton Khirnov
It's a private field, it should not be visible to callers. Deprecate AVCodecContext.thread_opaque
2013-11-04pthread_slice: rename ThreadContext -> SliceThreadContextAnton Khirnov
This should prevent confusion with frame threading.
