The "progress2" API in pthread_slice.c currently associates a progress
value with a thread rather than a job, relying on the broken assumption
that a job's thread number is equal to its job number modulo thread
count.
This removes this API entirely, and changes hevcdec to use a
ThreadProgress-based implementation that associates a
mutex/cond/progress value with every job.
Fixes races and deadlocks in hevdec with slice threading, e.g. some of
those mentioned in #11221.

(cherry picked from commit decc9e643c)
The arm/aarch64 horizontal filter reads one additional pixel beyond what
the filter uses. This can become an issue if the application does not
allocate larger buffers than what's required for the pixel data. If the
motion vector points to the bottom right edge of the picture this
becomes a read buffer overflow. This triggers segfaults in Firefox for
video resolutions which result in a page aligned picture size like
1280x640.
Prevent this by using emulated edge in this case.

(cherry picked from commit 060464105b)
This reduces the amount the horizontal filters read beyond the filter
width to a consistent 1 pixel. The data is not used so this is usually
not noticeable. It becomes a problem when the application allocates
frame buffers only for the aligned picture size and the end of it is at
a page boundary. This happens for picture sizes which are a multiple of
the page size like 1280x640. The frame buffer allocation is based on
its most likely done via mmap + MAP_ANONYMOUS so start and end of the
buffer are page aligned and the previous and next page are not
necessarily mapped.
This mirrors the aarch64 change.

Under these conditions like seen by Firefox a read beyond the end of the
buffer results in a segfault.
After the over-read is reduced to a single pixel it's reasonable to use
VP9's emulated edge motion compensation for this.
