790be3125d avcodec/acelp_pitch_delay: Inline small functions only used once
ff_acelp_decode_8bit_to_1st_delay3, ff_acelp_decode_4bit_to_2nd_delay3
and ff_acelp_decode_5_6_bit_to_2nd_delay3 are all only used once (by
g729dec) whereas ff_acelp_decode_9bit_to_1st_delay6 and
ff_acelp_decode_6bit_to_2nd_delay6 are completely unused; with the
possible exception of ff_acelp_decode_4bit_to_2nd_delay3, these
functions are so small that inlining them is appropriate; and as long as
ff_acelp_decode_4bit_to_2nd_delay3 is only called once, this is also
true for it.

3bf07b1a2d avcodec/bitstream: Rewrite code to avoid triggering compiler warning
Clang infers from the existence of a default case that said case can be
taken. In case of libavcodec/bitstream.c said default case consisted of
an av_assert1 that evaluates to nothing in case of the ordinary assert
level. In this case (that doesn't happen) a variable wouldn't be
initialized, so Clang emitted Wsometimes-uninitialized warnings.
Solve this by making sure that the default path also initializes
the aforementioned variable.

The counter for the number of styles is written on two bytes, ergo

78d5e1c653 avformat/Makefile: Remove unnecessary dependencies on vocdec
Commit 0d1229f1d2 factored the main part
of the voc demuxer's read_packet function out; yet when this Libav
commit was merged in f99195d56f, the
dependency of the other users of this function on vocdec.o was
unnecessarily kept. This commit fixes this.

While just at it, also disable the data only used by the voc demuxer
and muxer in voc.c if both of them are disabled.

ad58113afe avcodec/tiff_data: Move data to its only user
tiff.c is the only user of the data from tiff_data.c (the dependency of
the tiff encoder of it is spurious). Therefore this commit moves all the
data from tiff_data.c to tiff_data.h (which is only included by tiff.c)
and makes the objects declared therein static.

bb9167dbde avformat/isom: Split movaudio/movvideo tags off into a separate file
The NUT and avi demuxers only need ff_codec_movvideo_tags and so this
removes a dependency on the rest of isom.c as well as on mpeg4audio.c
(which isom depends on); it is similar for the Matroska demuxer and
muxers, except that the mpeg4audio.c dependency can't be avoided.

215536ad0c avformat/Makefile: Remove outdated AIFF demuxer dependency on iso_media
This is a result of the mov channel parsing stuff being factored out
of mov.c twice: Once in 91b782720f
to isom.c and later in 3bab7cd128.

Also remove the isom.h header; and while just at it, remove an unused
mathematics.h inclusion.

(isom.c actually depends upon mpeg4audio from libavcodec for
avpriv_mpeg4audio_get_config2 and avpriv_mpa_freq_tab; yet there is
no configure dependency for iso_media which leads to failure of shared
builds.)

d26198ada3 avcodec/g2meet, mjpegdec: Factor out common VLC initialization code
While just at it, remove the nb_codes parameter: It is redundant
(the number of codes is implicitly contained in the array containing how
many entries of a specific size there are) and for this reason it might
even be wrong, so it is better to check what is actually used instead.

7bf2b76b41 configure, libavcodec/Makefile: Fix avrn dependencies
The avrn decoder actually only needs one thing: The MJPEG decoder.
Instead the Makefile made it compile mjpegdec and configure required
some of the prerequisites of the MJPEG decoder (exif and jpegtables).
Even if all the prerequisites of the MJPEG decoder were required, it
would still not make the MJPEG decoder usable, because for that
the MJPEG decoder needs to be in the list of codecs in codec_list.c.
