Some invocations include a verb in the log message, others do not.  Yet
av_log_missing_feature expects callers to provide a verb.  Change the
function to include a verb instead and update the callers accordingly.
The result is a more natural function API and correct English in the
function invocations.

The vec_splat() intrinsic requires a constant argument for the
element number, and the code relies on the compiler unrolling
the loop to provide this.  Manually unrolling the loop avoids
this reliance and works with all compilers.

Enable dead store elimination.  The last few releases work no worse
with this flag than without.  Older versions failed to build some
source files when using this flag.

Tested to work with the gstreamer depacketizer.

Not all details are implemented, but it's enough for proper
playback as long as there is no packet loss.

Tested to work with the packetizer in gstreamer (which although
uses a different codec name, to clarify that it is still a spec
draft).

Rename the called dsp init functions to *_init_x86.

The tag @table expects @item to mark entries.

avconv provides an option to set it externally and there isn't a way for
the outer demuxer to report the inner demuxer flag.

Solves a bad interaction between mpegts and x264, but requires
additional setting for the user.

When there is only 1 channel, the planar and interleaved formats of the same
data type should be treated as identical.

Should fix fate-acodec-adpcm-ima_wav with several compilers.

It is used for multiple codecs.

An alpha specifier outside the valid range results in a conversion from
double to long with undefined result.  Range-checking the double and
only converting it after it passes avoids this.

Fixes fate-parseutils errors on some systems.

We don't need to return an error if the directory already existed.
We make sure that the directory actually is properly writeable later
within ism_write_header by writing a manifest anyway.
