The size-32 DCT_II has a special implementation which doesn't use
the normal tables.  Skipping allocation of these in this case saves
some memory.

The header is a part of an MP3 encoder that never saw the light of day.

This fixes the warning:
libavcodec/dfa.c:189: warning: unused variable ‘frame_end’

046f081b reorganized the CPPFLAGS to no
longer add -D_POSIX_C_SOURCE unconditionally, but only on systems (e.g.,
glibc based ones) that require it.  As kFreeBSD uses glibc, it needs to
be treated similar.

Additionally, _BSD_SOURCE is turned on to enable some additional types
such as caddr_t, which are normally enabled on BSD but not with glibc.

Also remove code that overwrites the C versions of functions in
sws_init_swScale_altivec(), so that it uses the C functions of files
if no altivec-optimized version exists.

Surround memset and ff_vp8_dct_cat_prob by X() in order to fix iOS build

SIGINT for quitting should be enough for everybody.

The later parsing of payload data depends on the configuration

parsing a data packet may lead to a crash.

In the main loop, stream_number is incremented after checking the stream type,
so the search usually will not find the wanted stream.

This patch eliminates the useless stream_number variable and introduces a new
one, called real_stream_index to store the real stream index of the current
stream, no matter if we are looping through all the streams or only the streams
of a program.
