a09bb3ba5e lavc: avoid invalid memcpy() in avcodec_default_release_buffer()
When the buf and last pointers are equal, the FFSWAP() results
in an invalid call to memcpy() with same source and destination
on some targets.  Although assigning a struct to itself is valid
C99, gcc does not check for this before calling memcpy().
See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32667

f32fd31858 g722: Change bits per sample to 4
Earlier, bits per sample was defined as 8, since
bits_per_coded_sample was used to indicate whether to ignore
the lower bits of the codeword, having values 6, 7 or 8.

g722 encodes 2 samples into one byte codeword, therefore the
bits per sample is 4. By changing this, the generated timestamps
for streams encoded with g722 become correct.

This makes timestamp generation for g722 data correct (both when
encoding and when demuxing from raw g722 files).

560f773c7d avcodec: change number of plane pointers from 4 to 8 at next major bump.
Add AV_NUM_DATA_POINTERS to simplify the bump transition.
This will allow for supporting more planar audio channels without having to
allocate separate pointer arrays.

f3a29b750a avcodec: move some AVCodecContext fields to an internal struct.
A new field, AVCodecContext.internal is used to hold a new struct
AVCodecInternal, which has private fields that are not codec-specific and are
used by general libavcodec functions.

Moved internal_buffer, internal_buffer_count, and is_copy.

6326afd5e9 avcodec: reject audio packets with NULL data and non-zero size
There is no valid reason the user should ever send such packets in the
first place, but the documentation for CODEC_CAP_DELAY states that the
codec is guaranteed not to get a NULL packet unless that capability is
set. That isn't true without preventing this case.

6e3ef511d7 Add the notion of pixel size in h264 related functions.
In high bit depth the pixels will not be stored in uint8_t like in the
normal case, but in uint16_t. The pixel size is thus 1 in normal bit
depth and 2 in high bit depth.

Preparatory patch for high bit depth h264 decoding support.

31d76ec288 In avcodec_open(), set return code to an error value only when an error occurs
instead of unconditionally at the start of the function.

This fixes a bug where a successful call to ff_thread_init() masks errors that
occur after that point in the function.  It also makes future bugs like this
less likely since the error code is now set near to the point in the code
where the error is found.
