Also add no-op fallbacks when threading is disabled.

This helps keeping the code clean if Libav is compiled for targets
without threading. Since we assume that no threads of any kind are used
in such configurations, doing nothing is ok by definition.

Based on a patch by wm4 <nfxjfg@googlemail.com>.

The Xvid IDCT is not MMX-specific.

This fixes cases where the scantable permuation would get overwritten by
the general idctdsp initialization.

The Xvid IDCT is only required to decode some Xvid-encoded MPEG-4 files,
so there is no point in having it as an unconditional part of idctdsp.

From the ARMv7 NEON version. 16 times faster as the C version, overall
more than 12% faster vorbis decoding on Apple's A7.

Conveniently (together with Justin's earlier patches), this makes
our vorbis decoder entirely independent of dsputil.
