This makes the lavf tests depend on all codecs and formats they use.

This makes the vsynth tests run only if the required codecs and

The LAME API documentation for the required buffer size refers to the size for
a single encode call. However, we store multiple frames in the same output
buffer but only read 1 frame at a time out of it. As a result, the buffer size
given in lame_encode_buffer() is actually smaller than what it should be.
Since we do not know how many frames it will end up buffering, it is best to
just reallocate if needed.

Bitrate calculation is off since the bluray spec always specifies
an even number of coded channels. This was honored in the decoder,
but not for bitrate calculation.

Raw audio does not provide valid audio tags while rawvideo does.
The fate refs have to be updated because it undoes the previous tag
change.

This way avserver only depends on the data structures of the ffm
demuxer, which it already does, and not also on private functions
being exported by the library.

For a sample size of 32 bits, the shift would overflow producing
undefined results.  Incidentally, in the only test currently using
32-bit samples, the output matches the reference exactly on most
systems meaning the bad 'max' value is never used.

Some systems, e.g. Minix, have sys/mman.h defining MAP_ANONYMOUS without
providing (working) mmap and friends.  The mmx filter generation code
checks only for MAP_ANONYMOUS, not for availability of mmap itself which
leads to build errors on aforementioned systems.

This changes the conditional compilation to use mmap only if all the
required functions are available.
