7644f5a807 lavc: replace avcodec_set_dimensions with ff_set_dimensions 
avcodec_set_dimensions() is supposed to be an internal utility function,
there is no reason whatsoever for it to be public. Therefore deprecate
it.

985f34b756 utils: fix avcodec_flush_buffers pre-reference counting compatibility 
The to_free AVframe must be freed just like the other ones.
Indeed, the calling application may expect all frames to be
released.

(This regression caused use-after-free in VLC with hwaccel.)

c24469e812 utils: add workaround for AVHWAccel in ff_get_buffer compat code 
Since c977039e58 plane count for
PIX_FMT_HWACCEL pixel formats is 0 instead of 1. The created dummy
AVBuffers are still bogus since AVFrame does not hold frame data when
AVHWAccels are used.

70762508ec lavc: Prettify printing of codec tags containing non alphanumeric characters 
Make av_get_codec_tag_string() show codec tag string characters in a more
intelligible ways. For example the ascii char "@" is used as a number, so
should be displayed like "[64]" rather than as a printable character.

Apart alphanumeric chars, only the characters ' ' and '.' are used
literally in codec tags, all the other characters represent numbers.

This also avoids relying on locale-dependent character class functions.
