e47f3e366b avcodec/g723_1enc: Remove unnecessary av_clipl_int32()
partial_corr is an int16_t and so the av_clipl_int32()
never clips and can be removed. This also avoids
undefined left-shifts of negative numbers.

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.

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.

5aabb2596f avcodec/codec_internal: Rename AVCodecDefault->FFCodecDefault
This structure is no longer declared in a public header,
so using an FF-prefix is more appropriate.

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.

f471caaf90 avcodec/g723_1enc: Avoid copying packet data, allow user-supplied buffers
When the packet size is known in advance like here, one can avoid
an intermediate buffer for the packet data by using
ff_get_encode_buffer() and also set AV_CODEC_CAP_DR1 at the same time.

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.

15ef16dce8 avcodec/g723_1enc: Avoid skip_put_bits()
If a bit is reserved, it matters very much what value it has, because
otherwise a decoder conforming to a future version of the standard might
interpret the output file in an unintended manner. This implies that
one must not use skip_put_bits() for it (which does not give any
guarantees wrt what ends up in the output (in case of a little-endian
bitstream writer (as here) it writes a 0 bit)); given that the reference
encoder as well as the earlier code write a zero bit at this place, the
new code does, too.
