This fixes standalone compilation of the msmpeg4v2, msmpeg4v3
and wmv2 encoders, that previously failed to link due to the
decoder codepaths requiring error_resilience.

Revert "removing lowres support"
...
There have been multiple user complaints about loosing this feature
while its not clear the 3% speedloss claims where real or fabricated.
My own testing indicates no statistically significant speed difference
both with mpeg2 and mpeg4, and if at all the code with lowres support
is a tiny bit faster than without.
This reverts commit 92ef4be4ab

msmpeg4v1: fix undefined behaviour in msmpeg4_decode_picture_header()
...
Because the order of evaluation of subexpressions is undefined, two
get_bits() calls may not be part of the same expression. In this
specific case, using get_bits_long() is simpler.
This fixes msmpeg4v1 decoding with armcc.
