Old versions of libxcb do not provide xcb_shape_rectangles().
The issue can be fixed differently but this small change fixes
some fate platforms and a user reported compilation problem.
Reported and tested by trac user kevmitch.
Fixes ticket #4067.

Similarly to the omit_tfhd_offset flag added in e7bf085b, this
avoids writing absolute byte positions to the file, making them
more easily streamable.
This is a new feature from 14496-12:2012, so application support
isn't necessarily too widespread yet (support for it in libav was
added in 20f95f21f in July 2014).

The custom IO flag actually never is set for muxers, only for
demuxers, so the check was pointless (unless a user intentionally
would set the flag to signal using custom IO).

If one track doesn't have any samples within a moof, no traf/trun
is written for it. When the omit_tfhd_offset flag is set, none
of the tfhd atoms have any base_data_offset set, and the implicit
offset (end of previous track fragment data, or start of the moof
for the first trun) is used.

__sync built-ins are considered legacy and will be deprecated.
These new memory model aware built-ins have been available since GCC 4.7.0
Use them by default when available except for __atomic_compare_exchange_n(),
which is slower, and is instead implemented as a fallback for when and if gcc
removes the legacy __sync built-ins.

To keep h264 parsing simple and fast, I used the framesize for selecting the right Panasonic codec label. The framesize is fixed for Panasonic AVC Intra.
This patch only supports AVCI50/100. But in all flavours, i.e. with no SPS/PPS in header.

The fieldmatch filter has no problem with mixed telecined and
progressive content but the decimate filter does not detect the
changing framerate and drops progressive frames.
* cehoyos/master:
Mention in the documentation that fieldmatch needs cfr input.
Use v4l2 input format automatically if filename starts with "/dev/video"
Print a warning if a subtitle demuxer changes utf16 to utf8.
Do not set the lame quality if the user didn't request it.
Merged-by: Michael Niedermayer <michaelni@gmx.at>
This can be improved in the decimate filter but for the moment
explicitely mentioning that mixed telecined and progressive
content is unsupported is an improvement.
Fixes ticket #3968.
