Performance in the horizontal scenario seems worse than scalar. x86
SSE2 and AVX optimisations are s
Judging by the coefficients, the last round of add/sub can overflow
to 17 bits with a very small probability just as with the 8-point
transform. This is not observed under FATE, but better safe than sorry.

Performance is (unfortunately) the same as with non-MBAFF, since the
hardware under test does not short-circuit vector tail calculations.
(IMO, a generic solution or work-around should be agreed on, rather
than bespoke approaches all over the place.)

fd_dup is unused when fd and pipe have been disabled. This also

The code can be simplified by always creating mutex/cond. I'm not sure
it worth the overhead. Please note !HAVE_THREADS don't have the same
problem since it has mock implementation of ff_mutex_lock/unlock.
