avcodec/snow: Move decoder parts out of ff_snow_common_init_after_header

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt(a)outlook.com> | Mon Sep 25 18:57:47 2023 +0200| [00ba78cd6fb8fb7cbd20a36e840ddde3eda0dca0] | committer: Andreas Rheinhardt avcodec/snow: Move decoder parts out of ff_snow_common_init_after_header They are not common. Furthermore, this file is pulled in when linking checkasm and up until now, the calls to ff_get_buffer() and av_codec_is_decoder() caused all of libavcodec to be pulled in as well. Besides being bad size-wise this also has the downside that it pulls in avpriv_(cga|vga16)_font from libavutil which are marked as being imported from another library when building libavcodec as a DLL; this breaks checkasm because it links both lavc and lavu statically.

avcodec/snow: Split ff_snow_get_buffer()
by Andreas Rheinhardt 28 Sep '23

28 Sep '23

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt(a)outlook.com> | Mon Sep 25 18:21:55 2023 +0200| [418332e01ce99d43f218504e4e4e1b4ea89c9a49] | committer: Andreas Rheinhardt avcodec/snow: Split ff_snow_get_buffer() The part of said function that is common to both encoder and decoder is negligible since c954cf1e1b766a0d1992d5be0a8be0055a8e1a6a and more than offset by the costs of "Am I an encoder?" checks. So move allocating the frames to the encoder and decoder directly. Also rename ff_snow_frame_start() to ff_snow_frames_prepare(), because a frame without a buffer has not been properly started.
