Up until now, codec.h contains both public and private parts
of AVCodec. This exposes the internals of AVCodec to users
and leads them into the temptation of actually using them
and forces us to forward-declare structures and types that
users can't use at all.
This commit changes this by adding a new structure FFCodec to
codec_internal.h that extends AVCodec, i.e. contains the public
AVCodec as first member; the private fields of AVCodec are moved
to this structure, leaving codec.h clean.

Also move FF_CODEC_TAGS_END as well as struct AVCodecDefault.
This reduces the amount of files that have to include internal.h
(which comes with quite a lot of indirect inclusions), as e.g.
most encoders don't need it. It is furthemore in preparation
for moving the private part of AVCodec out of the public codec.h.

The only unorthodox thing that this codec's init function does
is calling ff_get_format(). Yet this is supposed to be save,
as any get_format callback already has to deal with the scenario
of different AVCodecContext's calling it simultaneously.

Given that the AVCodec.next pointer has now been removed, most of the
AVCodecs are not modified at all any more and can therefore be made
const (as this patch does); the only exceptions are the very few codecs
for external libraries that have a init_static_data callback.

Because the properties of frames returned from ff_get/reget_buffer
are not reset at all, lots of returned frames had palette_has_changed
wrongly set to 1. This has been changed, too.

This reverts commit 691dec6201.
The commit did not fix ticket #3215, it was fixed one commit earlier.
The revert may break other use-cases but they should be fixed differently,
the offending commit introduced too many problems.
Fixes ticket #3377.
Fixes ticket #3378.
This is required specifically for setting frame->format to -1,
otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading
the format from the output decoded frame will get misled.
In particular fix regressions occurring with the pending vsrc_buffer
patch.
None of these symbols should be accessed directly, so declare them as
hidden.

(cherry picked from commit d36beb3f69)
Other parts of FFmpeg use NE (native endian) rather than ME (machine).
This makes it consistent.

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.

AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

Also reset the minor version and fix the forgotton change to libfaad.
Note: The API/ABI should not be considered stable yet, there still may
be a change done here or there if some developer has some cleanup ideas and
patches!
