lavd/v4l2: do not fail when VIDIOC_ENUMSTD returns EINVAL without a valid match

With some (buggy) drivers, the VIDIOC_G_STD ioctl returns a std_id that cannot
be matched with any of the enumerated v4l2_standard structures (for example
std_id = 0 or std_id = 0xffffff). Do not fail when we reach the end of the
enumeration without a valid match.

Fixes ticket #2370

lavf: Make probe_codec return an error code

x86: Add an xmm clobbering wrapper for avcodec_encode_video2

This is required since 187105ff8 when we started trying to
wrap this function as well.

lavf: Don't explicitly flush after each written packet in muxers

Since 596e5d4783, this is not necessary anymore. It also allows to
actually disable the flushing, improving write performance (but
possibly giving worse latency in real-time streaming).

Signed-off-by: Martin Storsjö <martin@martin.st>

lavf: Add a flag to enable/disable per-packet flushing

This is enabled by default and can be disabled with
"-fflags -flush_packets".

Inspired by a patch from Nicolas George <nicolas.george@normalesup.org>.
