and remove FF_CODEC_CAP_INIT_THREADSAFE
All our native codecs are already init-threadsafe
(only wrappers for external libraries and hwaccels
are typically not marked as init-threadsafe yet),
so it is only natural for this to also be the default state.

This is possible, because every given FFCodec has to implement
exactly one of these. Doing so decreases sizeof(FFCodec) and
therefore decreases the size of the binary.
Notice that in case of position-independent code the decrease
is in .data.rel.ro, so that this translates to decreased
memory consumption.

This increases type-safety by avoiding conversions from/through void*.
It also avoids the boilerplate "AVFrame *frame = data;" line
for non-subtitle decoders.

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.

Also include channel_layout.h directly wherever used.

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.

Set the sample rate when parsing the header instead and only copy the
value in the decoder and the parser.

convert_input, a nontrivial auxiliary function used by both the general
parsing code as well as the decoder itself, has been duplicated in
c7016e35a624a75bb5b82bee932ddfe28d013b3f; this commit removes said
duplication.

These two functions are always called after another; after all, what
ff_dolby_e_parse_init does is obviously part of parsing the frame header.
Also move the DolbyEHeaderInfo into DBEContext so that parsing the frame
header only needs one struct (both users used a DBEContext immediately
followed by a separate DolbyEHeaderInfo).

Neither module should depend on the other.
Move shared functions to its own file for this purpose, and ensure
source files are compiled only when the required modules are enabled.

Avoid undefined behavior in skip_input() by checking that enough data is
available before incrementing input pointer.
Check return values of parse_key() and skip_input() and exit early with
error if there is not enough data.
