Such buffers are not malloced thus freeing would be bad.
Note though this condition never could have happened so this
is more for correctness sake and not a true bugfix

This performs the start code search which was previously part of
h264_find_frame_end() - the most CPU intensive part of the function.
By itself, this results in a performance regression:

but this can more than be made up for by platform-optimised

Each AVStream struct for an H.264 elementary stream actually has two
copies of the H264DSPContext struct (and in fact all the other members
of H264Context as well):
((H264Context *) ((AVStream *)st)->codec->priv_data)->h264dsp
((H264Context *) ((AVStream *)st)->parser->priv_data)->h264dsp
but only the first of these was actually being initialised. This
prevented the addition of platform-specific implementations of
parser-related functions.

rtsp: Don't include the listen flag in the SDP demuxer flags

This provides at least some protection against potential accidental
corruption of AVIO buffer workspace.

Fixes commandline parsing on Cygwin (on 64 bit, and on very recent
32 bit), where the configure check does find the CommandLineToArgvW
function (since it exists in the link libraries and in the headers),
but whose GetCommandLineW() only returns the application's path.
(This is due to a cygwin internal optimization, see
http://cygwin.com/ml/cygwin/2013-07/msg00538.html for details.)
Arguments are only given through main's argc/argv, and they're already
UTF-8.

* cigaes/master:
ffmpeg: remove obsolete workaround in trim insertion.
lavu/log: do not skip overwritten lines.
Merged-by: Michael Niedermayer <michaelni@gmx.at>
The bug it was working seems to have been fixed.
This change causes ffmpeg to use the trim filter to implement
the -t option.
FATE tests are updated due to the more accurate handling of
the last packets.
It's only relevant for the RTSP demuxer. Similarly, the custom_io
flag is only present in the SDP demuxer options list.
