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.
Also move the declaration to internal.h, and add restrict qualifiers
to the declaration (as in the implementation).

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.

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
in two planes.
AVCodecContext release_buffer() shall be NULL for audio codecs using
get_buffer. The backward compatibility code hence have to check before
calling it.
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.

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.
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.
Avoids memleaks with audio when extended_data is nontrivial and the user
doesn't reset the frame.
Shouldn't have any effect for video for now, but might be useful in the
future.
Error out on init if a codec with CODEC_CAP_EXPERIMENTAL is requested
and strict_std_compliance is not FF_COMPLIANCE_EXPERIMENTAL.
Move the check from avconv to avcodec_open2() and return
AVERROR_EXPERIMENTAL accordingly.

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.
