6b6f7db819 avcodec: add AVCodecContext.frame_num as 64 bit variant to frame_number
Frame counters can overflow relatively easily (INT_MAX number of frames is
slightly more than 1 year for 60 fps content), so make sure we use 64 bit
values for them.

Also deprecate the old 32 bit frame_number attribute.

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.

a499b4345b avcodec: Make ff_alloc_packet() based encoders accept user buffers
Up until now, these encoders received non-refcounted packets
(whose data was owned by the corresponding AVCodecContext)
from ff_alloc_packet(); these packets were made refcounted lateron
by av_packet_make_refcounted() generically.
This commit makes these encoders accept user-supplied buffers by
replacing av_packet_make_refcounted() with an equivalent function
that is based upon get_encode_buffer().

(I am pretty certain that one can also set the flag for mpegvideo-
based encoders, but I want to double-check this later. What is certain
is that it reallocates the buffer owned by the AVCodecContext
which should maybe be moved to encode.c, so that proresenc_kostya.c
and ttaenc.c can make use of it, too.)

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.

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.

40cf317d09 avcodec/smcenc: Move PutByteContext to stack
This context is transient, so putting it on the stack is more natural.
Also reduces codesize: 24E6->2296 B with GCC 10 and -O3.
