vmdaudio: simplify vmdaudio_decode_frame() by handling block_type first, then making a single call to vmdaudio_loadsound().

This also adds output buffer size checks for AUDIO and SILENCE block types.

Map EAGAIN and EINTR from ff_neterrno to the normal AVERROR()
error codes. Provide fallback definitions of other errno.h network
errors, mapping them to the corresponding winsock errors.

This eases catching these error codes in common code, without having
to distinguish between FF_NETERRNO(EAGAIN) and AVERROR(EAGAIN).

This fixes roundup issue 2614, unbreaking blocking network IO on
windows.

It was doubled in size for the LTP implementation. This brings it back
down to its original size.

This adds the AAC codec to the list of audio codecs that results
in a PES stream_id of 0xc0 (audio stream).

GCC 4.3 and later are more particular about signedness matching
in vector operations.  The operations under if(rangered) were
missing assignments and thus had no effect.

Merging these functions allows merging some loops, which makes the
results (particularly after SIMD optimizations) much faster.

Advantage is that it allows us to combine several loops into a single
one, and these can eventually be merged into the IDCT itself. Also, it
allows us to remove vc1_put_block(), and makes CODEC_FLAG_GRAY faster.
