Add missing multiple inclusion guards; clean up #endif comments;
add missing library prefixes; keep guard names consistent.

If done before, some parameters aren't known yet.

With svq3/rtp, initializing before some parameters are known
can lead to calling av_malloc(0), which on OS X currently returns
broken pointers.

libavformat/riff.c has been writing channel_layout for as long as
the field exists.

* ffmpeg-mt/master:
      Update todo.
      h264: add an assert that copied pictures are valid picture pointers
      valgrind-check: run with 1 and 3 threads
      h264: When decoding a packet with multiple PPS/SPS, don't start the next thread until all of them have been read
      Allow some pictures to be released earlier after 51ead6d2c4
      h264: fix slice threading MC reading uninitialized frame edges.

    Please see ffmpeg-mt for a list of authors of these changes.

    Conflicts:

Fixes compilation with mp3lame enabled.

Fixes memory leaks which are the result of overwriting already-initialized
MDCT contexts during context reinitialization, e.g. in valgrind
fate-aac-latm_000000001180bc60.

When backing up the top-left border, check that the top-left
(rather than left) MB indeed does belong to our slice. If it
doesn't, backing up has no positive effect but may accidentally
interfere with other threads writing in the same space.

Fixes occasional one-off effects when enabling slice-MT.

The prototype should use the same typedefs as the definition, or it
will fail where int32_t is not int (DOS apparently).

This is consistent with how all other table generation programs are named.
Moreover this ensures that the cos table generation program is correctly
deleted when cleaning the tree.

tableprint.c serves little purpose on its own and removing it allows building
the table generator programs with the normal HOSTPROGS Makefile rules.

This collapses the make rules for the trig tables into a pattern
rule.  Based on a patch by Diego, modified to avoid using fragile
make constructs and allow future addition of fixed-point sin tables.

These structs are only used in mpegaudiodec.c, so move them there
and remove no longer needed #include lines from mpegaudio.h.

This separation allows these functions to be used in a cleaner
fashion from other codecs (e.g. qdm2) and simplifies creating
optimised versions of them.

This will allow audio decoders to support output of different sample formats
