This allows for some simplifications like removing some outer loops
and gives much better performance for thread_count > number of idle CPUs.

processing with jobs > threads without wasting too much memory.
It also avoids needing a separate int array when the only additional data
the jobs needs is a single int running from 0 to count-1.

A certain rotten fruit operating system doesn't provide the 8-byte stack
alignment required by the standard ARM ABI, so align it manually.

Recent versions of gcc generate movw/movt pairs, and the linkers fail
to handle the associated relocations properly.  Those responsible at
Codesourcery have refused to consider fixing this.  Blame them for
making shared libraries slower than they need to be.

This is not correct, but libtheora does not seem to provide a way
to get the correct value, and this is necessary to make encoding
produce sensible time stamps when encoded content is variable
FPS or the time base is simply different from FPS.
Somewhat fixes issue 1197.
