2eba9087f3 lavc: make up a fake frame channel layout when there is no real one. 
This should ensure that a valid channel layout is always set on a frame,
until a better solution is implemented.

1afddbe59e avpacket: use AVBuffer to allow refcounting the packets. 
This will allow us to avoid copying the packets in many cases.

This breaks ABI.

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.

d2a25c4032 get_buffer(): do not initialize the data. 
There may be more decoders that rely on this. Those should be found and
fixed.

bd255f9feb lavc: set frame parameters after decoding only if necessary 
Direct rendering capable decoders call get_buffer() which will set the
frame parameters.

Prevents frames with wrong parameters when a decoder outputs delayed
frames after a resolution or pixel format change.

0366664ef9 lavc: check channel count after decoder init 
Ensures the decoder did not set channel count to an insanely high value
during initialization, which could cause large memory usage when it tries to
get a buffer during decoding.

f75f4194d1 Restructure av_log_missing_feature message 
Some invocations include a verb in the log message, others do not.  Yet
av_log_missing_feature expects callers to provide a verb.  Change the
function to include a verb instead and update the callers accordingly.
The result is a more natural function API and correct English in the
function invocations.
