Notwithstanding the return value the frame should be freed if
is not going to be used.

e036bb7899 lavc: clear AVBuffers on decoded frames if refcounted_frames is not set 
Otherwise some code might mistakenly think it is allowed to unref those
buffers, which would lead to double unref.

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.

75644335b9 lavc: Move start code finding to utils.c 
This allows dropping the mpegvideo dependency from a number of
components.

This also fixes standalone building of the h264 parser, which
was broken in 64e438697.

c977039e58 lavc, lavfi: fix counting number of planes in AVBufferRef wrappers 
Number of planes is not always equal to the number of components even
for formats marked with PIX_FMT_PLANAR -- e.g. NV12 has three components

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.
