e6bfb14223 avcodec/aptxdec: Process data in complete blocks only
The APTX (HD) decoder decodes blocks of four (six) bytes to four
output samples. It makes no sense to handle incomplete blocks:
They would just lead to synchronization errors, in which case
the complete frame is discarded. So only handle complete blocks.
This also avoids reading from the packet's padding and writing
into the frame's padding.

48286d4d98 avcodec/codec_internal: Add macro to set AVCodec.long_name
It reduces typing: Before this patch, there were 105 codecs
whose long_name-definition exceeded the 80 char line length
limit. Now there are only nine of them.

66b691f99f avcodec/internal: Move ff_get_buffer() to decode.h
Only used by decoders (encoders have ff_encode_alloc_frame()).

Also clean up the other headers a bit while removing now redundant
internal.h inclusions.

21b23ceab3 avcodec: Make init-threadsafety the default
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.

4243da4ff4 avcodec/codec_internal: Use union for FFCodec decode/encode callbacks
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.

ce7dbd0481 avcodec/codec_internal: Make FFCodec.decode use AVFrame*
This increases type-safety by avoiding conversions from/through void*.
It also avoids the boilerplate "AVFrame *frame = data;" line
for non-subtitle decoders.

20f9727018 avcodec/codec_internal: Add FFCodec, hide internal part of AVCodec
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.

a688f3c13c avcodec/internal: Move FF_CODEC_CAP_* to a new header codec_internal.h
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.

a78f136f3f configure: Use a separate config_components.h header for $ALL_COMPONENTS
This avoids unnecessary rebuilds of most source files if only the
list of enabled components has changed, but not the other properties
of the build, set in config.h.

a247ac640d avcodec: Constify AVCodecs
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.
