This will allow us to avoid copying the packets in many cases.

This breaks ABI.

Upstream decided to split the paranoia interface and move the headers
accordingly.

Codec timebase is supposed to be set by decoders only.

v4l2_read_header() does no cleanup, so it can return directly, without
any need for goto.

The function find_things() in configure is confused by component
registration calls as part of multiline macros defining combined
component registration.  Coalesce those macros into one line to
work around the issue.

Also reorder some other #include when applicable.

DV1394_NTSC has a lower value than DV1394_PAL.

Anonymous structs cannot be forward declared and have no benefit.

We generally do not declare variables within for statements and
there are compilers that choke on such constructs.

Also remove one pointless zero initialization in rangecoder.c.

When using "-f x11grab -i :0.0" valgrind reports a definitely lost
memory block with this message:

==31544== 5 bytes in 1 blocks are definitely lost in loss record 1 of 2

The 5 bytes lost are the ones from param = av_strdup(":0.0"), so let's
free param in the exit path.

Also check the av_strdup() return value.

Note: calling av_free(param) even when av_strdup() fails and param is
NULL is OK and keeps the code simpler without adding another label to
skip av_free().
