The variable is copied to subsequent threads at the same time, so this
may cause wrong ref_count[] values to be copied to subsequent threads.

This bug was found using TSAN and Helgrind.

Original patch by Ronald, adapted with a local_ref_count by Clément,
following the suggestion of Michael Niedermayer.

seekability probing prevents the header from being added.

This only adds a subset of the frame rates that can be stored, a full list
would be more than 500 entries. Such full list could (and should) be added
if it has a usecase but the number of users of even the now added rates
seem rather small.

Discontinuous transmission is an addition to VAD/VBR operation, that
allows to greatly reduce bitrate for silent chunks or stationary
noises.

The value used in allocation is based on a estimate of the
maximum size of the spectral coefficients multiplied with 2
and rounded up. The exact or a tighter limit should be
found and used instead. But this issue shouldnt be left
open until someone works on that.

ff_get_cpu_flags_x86() requires cpuid(), which is conditionally defined
elsewhere in the file.  Surrounding the function body with ifdefs allows
building even when cpuid is not defined.  An empty cpuflags mask is
returned in this case.

Now that there is CPU detection in YASM, there will always be one of
inline or external assembly enabled, which obviates the need to fall
back on CPU detection through compiler intrinsics.

This allows detecting CPU features with builds that have neither
gcc inline assembly nor the right compiler intrinsics enabled.

This works with gcc.  Other compilers might need to have a flag
mapping added.
