avio: avio_ prefixes for get_* functions

In the name of consistency:
get_byte -> avio_r8
get_<type> -> avio_r<type>
get_buffer -> avio_read

get_partial_buffer will be made private later

get_strz is left out becase I want to change it later to return...

Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice.

This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.

Remove explicit filename from Doxygen @file commands.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

Define AVMediaType enum, and use it instead of enum CodecType, which
is deprecated and will be dropped at the next major bump.

Fix overflow check insufficiently improved in r19840.
It assumes that sizeof(vmd_frame) < 64k, otherwise an additional
check to ensure sound_buffers <= UINT_MAX / sizeof(vmd_frame) would be necessary.

Improve sierravmd probe. It is still quite weak, but further improvements
are non-obvious and probably need a large (about 1kB at least) probe buffer.

Extend check for integer overflow for malloc argument to take into account
also the addition of "sound_buffers" not only the multiplication.

Use full internal pathname in doxygen @file directives.
Otherwise doxygen complains about ambiguous filenames when files exist

VMD first chunk of audio is not coded as many separate chunks of block_align
size. Thus, make demuxer and decoder handle it as a whole.

The POSIX namespace shall be held sacrosanct. To that end,
continue eliminating _t from structure names in FFmpeg.

Remove offset_t typedef and use int64_t directly instead.
The name offset_t is easily confused with the standard off_t type and
*_t is POSIX reserved namespace if any POSIX header is included.
