This should be faster, is less code and fixes issue 2524
(allocation error would lead to crash).

The key string is supposed to contain the equals character,
too.  Since the checked string was wrong, and the return value
check was wrong too, it incorrectly seemed to work right before.

If audio_sync_method is >1 the resampler is used for audio drift
compensation, and do_audio_out() was causing an assert failure because
audio_resample was not set.

Fix issue 2516, which was introduced by SVN r25939.

With the removal of the libmpeg2 bitstream reader, MIN_CACHE_BITS
is always >= 25, so tests against smaller values can be removed.

These whitespace changes improve the readability of the get_bits
macros.
Signed-off-by: Mans Rullgard <mans@mansr.com>

Some of the macros in get_bits.h include a final semicolon,
some do not.  This removes these or adds do {} while(0) around
the macros as appropriate and adds semicolons where needed in
calling code.

Using the libmpeg2 reader causes errors in a multitude of places,
including MPEG and H264 codecs.  As the advantage of this reader
is questionable, removing it seems the sensible course of action,
especially considering the simplifications this allows elsewhere
with the bit cache size increasing from 17 to 25 bits as minimum.

Don't free RBSP tables (containing decoded NAL units) on resolution

C99 variadic macros require more arguments than there are named
parameters in the definition.  This means we must use an extra
indirection to avoid having two different macros for arrays with
one resp more than one dimension.
