This was done with the help of callcatcher [1]. Only functions which
are statically known to be unused are removed.
Some unused functions are not removed yet, because they might be needed
in the near future (such as open_output_stream for the encode branch).
There is one user visible change: the --subcc option did nothing, and is
removed with this commit.

Including <malloc.h>, especially if all you want is malloc(), has no
legitimate uses (on sane platforms at least). Remove the check for it,
and remove all uses in the code.
Remove unused check for alloca().
Most of these demuxers and decoders are provided in better form by
libav, while the mplayer builtin ones are essentially unmaintained. The
only legimitate use case for not using the libav ones was working around
libav bugs or bugs related to the way mplayer uses libav. Instead of
trying to keep dead code alive, development effort should go into
improving libav or the mplayer libav glue code.
Note that the libav demuxer have been preferred over the mplayer builtin
ones for a while in mplayer2. There were some exceptions: playing DVDs
with dvdnav or playing network sources. (That's because some stream
modules and network.c requested explicit file formats, such as
DEMUXER_TYPE_MPEG_PS, which mapped to builtin demuxers.) With this
commit, they are switched to use libav. One caveat is that the requested
format is not passed to libavformat, instead we rely on the auto probing
to select the correct libav demuxer (see code in demux_open_stream()).
There was some confusion about the "flags" field in demuxer packets.
Demuxers set it to either 1 or 0x10 to indicate a keyframe (and the
field was not used to indicate anything else). This didn't cause
visible problems because nothing read the value. Replace the "flags"
field with a boolean "keyframe" field. Set AV_PKT_FLAG_KEY based on
this field in packets fed to libavcodec video decoders (looks like PNG
and ZeroCodec are the only ones which depend on values from demuxer;
previously this was hardcoded to true for PNG).
Make demux_mf set the keyframe field in every packet. This matters for
PNG files now that the demuxer flag is forwarded to libavcodec.
Fix logic setting the field in demux_mkv. It had probably not been
updated when adding SimpleBlock support. This probably makes no
difference for any current practical use.
Disable compilation of demux_ty_osd.c because of its GPL v2-only
license. This only affects TiVo files with -subcc. After this no
v2-only code should get compiled (yuv4mpeg_intern.h has a v2-only
license, but the contents of the header look like they're not
copyrightable).
Do not pointlessly cast the return value of memalign().
memalign() returns void*, which is compatible with any pointer in C.
