The PCM_DVD encoder would be left unused, as allcodecs.c properly declared
it as being decoder-only, but it would still be built into the object file.

Since there is no block of code to properly encode this PCM format, it's
not a full codec.

The dprintf macro is no-op when DEBUG is unset, so there is no need to
put it conditional to DEBUG.

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
change, because we actually need this data to decode the frame after
reiniting (with new resolution). Fixed issue 2393.

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.

DTS-HD HRA streams do not always have an XBR extension in the extension
substream. Instead they can have only XXCh and X96 extensions in
there and still be considered DTS-HD HRA.

This is also confirmed with Onkyo TX-SR607 receiver which recognizes
such a stream as HiRes Audio.
