Untangle eamad from the mpeg12.h header and speed up rebuilding.

Having this macro in an header only facilitates the use of such header.
The code increase is minimal and files have one less dependency
on mpegvideo.h.

Mark it as static.

It is only used in one place, and it is small enough that it might be
called directly.

display_matrix_size is only initialized when av_stream_get_side_data()
returns a side data pointer. The code is safe since the only effect this
has is setting the display_matrix pointer to NULL which it was already
anyway.

It is necessary to avoid circular header dependencies.

The main ff_alloc_picture() function is made more generic with all the
parameters necessary as arguments. This will allows to move most of the
related functions to a separate file later.

Right now wrappers are provided to try and minimize the number of
changes in the code.

Use more generic arguments and remove its static attribute since it will
be moved to a separate file.

The C runtime C99 compatibility had been improved a lot and it now
rejects some of the compatibility defines provided for the older
versions.

Many thanks to Ray for the time spent testing.

The channel configuration can be delivered only by the PCE,
try to parse it first and not try to decode until a channel
configuration is set.

These are defined in ISO/IEC 14496-3:2009/PDAM 4 for 6.1 and 7.1.
It also defines another 7.1 layout with configuration 14, that one
is not added here for now.

FDK AAC encoder outputs SCE(front)+CPE(front)+CPE(back)+CPE(back) on
MODE_7_1_REAR_SURROUND configuration.
Since decoder couldn't properly map 4 back channels, decoding failed
unless -request_channel_layout 0x8000000000000000 has been specified.
Now we treat first CPE(back) as CPE(side) on channel mapping.

Support only streams with Content-Length.

The decoder assigns channels using default channel configuration
for 5.1ch when it parses an ADTS frame header using consecutive
channel ids.

When a PCE comes, it reassigns channels using PCE configuration
using directly the ids provided. They can be arbitrary.

Always use consecutive channel ids to avoid decoding glitches due
spurious reconfigurations due the channel ids mismatch between the
two otherwise-identical channel maps.

And make sure to check INTER_BLOCK as had been fixed by Michael

These are only necessary once/if avconv gets support for this hwaccel.
While that obviously is desireable, we don't have it yet, and they
currently only are a distraction.
