streamid does not work with newaudio, newvideo, newsubtitle

fixes issue2465.

The problem is that the ffmpeg (the app) -streamid option did not work
with -newaudio/-newvideo/-newsubtitle.

The cause was a conflict between the feature where streamid values were
reset to default for each output filename, and the implementation of
-new*, which requires that the -new* option be specified after the
target filename.

My patch changes the ffmpeg behavior so that user-specified streamid
values apply to all the following output files on the command line
(rather than just the next output filename.)

dca: consider a stream with XXCh/X96 in ExSS as DTS-HD HRA

DTS-HD HRA streams do not always have an XBR extension in the extension
substream. Instead they can have only XXCh and X96 extensions in
there and still be considered DTS-HD HRA.

This is also confirmed with Onkyo TX-SR607 receiver which recognizes
such a stream as HiRes Audio.

configure: better test for mktemp

Some variants of mktemp require a template, so provide one when
checking for the command.  We already supply a template in the
subsequent uses of mktemp.
