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.

Fixes Bugzilla #279.

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().

Remove some unneeded memsets.

Instead of busy waiting use poll();

Let pass the codec name to -pixel_format and introduce -input_format.

V4L2_FMT_FLAG_EMULATED was added in 2.6.32.

Make use of the experimental framesize enumeration ioctl if available.

Unbreak direct streamcopy.

Check capabilities directly in the function, further simplify the code.

Only mmap is supported.
