libavcodec/libspeexdec.c:108: warning: passing argument 2 of ‘speex_bits_read_from’ discards qualifiers from pointer target type

libavcodec/libopenjpeg.c:100: warning: passing argument 2 of ‘opj_cio_open’ discards qualifiers from pointer target type
/usr/include/openjpeg.h:770: note: expected ‘unsigned char *’ but argument is of type ‘const uint8_t *’

User-provided data should never trigger an assert; return error instead.
Also fix an instance of get_bits where get_bits_long should have been used.

This eliminates the following warning:
libavcodec/vaapi_mpeg2.c:112:14: warning: variable 'start_code' set but not used

An official specification now exists and it is both more detailed and
easier to understand than the incomplete notes available here.

Fixes a crash when forcing libc to strictly adhere to malloc sizes.

Prevents overflows on very bright scenes when adding dither,
which may lead to black dots.

The file name is redundant and brittle across file renamings.

Without it, Doxygen cannot separate them into different sections.

libavformat/utils.c:599: warning: (near initialization for ‘ap.time_base’)

This doesn't access avcodec_opts, so it works with the new options
passing system.

Makes opt_bitrate() unneeded, so it's removed.

This fixes a bunch of related warnings where Doxygen assumed that the
documentation belonged to the macro and not the function.

This fixes a bunch of unused function warnings.
