mov: always check avio_read return value
...
If avio_read fails, the buffer can contain uninitialized data.
This fixes 'Conditional jump or move depends on uninitialised value(s)'
valgrind warnings, and addresses a few memleaks.

pixfmt: remove misleading and broken documentation
...
This was probably broken some time ago. The breakage is now part of the
ABI. For example, we have:
AV_PIX_FMT_XYZ12BE
AV_PIX_FMT_NV16
AV_PIX_FMT_NV20LE
AV_PIX_FMT_NV20LE is wrong. It has the value 113, but as little-endian
format it should be even. This must have been quite obvious when these
formats were added (because of the AV_PIX_FMT_XYZ12BE entry), but
nobody cared or knew about this.
The future libavutil major bump will also break this additionally,
because disabling FF_API_VDPAU will remove an odd number of entries from
the middle of the enum.
