236a550c3f Fix a typo in the x86 asm version of ff_vector_clip_int32()
Specifies the correct number of xmm registers used so that they can be saved
and restored on Win64 if necessary.

3c432631e9 pcmenc: Do not set avpkt->size.
It is already the correct size as set by ff_alloc_packet().

1a670973a7 ff_alloc_packet: modify the size of the packet to match the requested size
This will simplify encoders which use this function to request the exact
packet size rather than the maximum size.

e67e3a3f4a fate-golomb: extend golomb-test to get_ue_golomb_long()
get_ue_golomb_long() is only tested for values up to 2^15 - 2 since
we can not write larger values.
Silence the test on success and return a non-zero value on error.
Use an heap scratch buffer instead of large stack buffer.
Remove unneeded includes.

bc90199848 lavc: set AVCodecContext.codec in avcodec_get_context_defaults3().
This way, if the AVCodecContext is allocated for a specific codec, the
caller doesn't need to store this codec separately and then pass it
again to avcodec_open2().

It also allows to set codec private options using av_opt_set_* before
opening the codec.

af08d9aeea lavc: add avcodec_is_open().
It allows to check whether an AVCodecContext is open in a documented
way. Right now the undocumented way this check is done in lavf/lavc is
by checking whether AVCodecContext.codec is NULL. However it's desirable
to be able to set AVCodecContext.codec before avcodec_open2().
