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.

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.

This does the same thing and also fixes the trapping in
some (possibly broken) shells.

name and provider_name were set but since the muxer uses service_provider
and service_name use them.

Apparently some broken taggers prepend a new ID3v2 tag leaving the
existing one intact. Our parser currently reads all tags and overwrites
existing values with supposedly outdated ones.

libavcodec minor version is > 99 so when printing the library versions
the output is a little bit broken:

  libavutil    50. 36. 0 / 50.36. 0
  libavcore     0. 16. 1 /  0.16. 1
  libavcodec   52.108. 0 / 52.108. 0
  libavformat  52. 94. 0 / 52.94. 0
  libavdevice  52.  2. 3 / 52. 2. 3
  libavfilter   1. 74. 0 /  1.74. 0
  libswscale    0. 12. 0 /  0.12. 0

Change the formating to look like this:

  libavutil    50. 36. 0 / 50. 36. 0
  libavcore     0. 16. 1 /  0. 16. 1
  libavcodec   52.108. 0 / 52.108. 0

This patch adds support in mpegts muxer for using service_provider and
service_name metadata to set service_provider_name and service_name
fields in SDT.

Example usage:
   ffmpeg -i file.ts -f mpegts -re -acodec copy -vcodec copy -f mpegts \
       -metadata service_provider="Some provider" \
       -metadata service_name="Some Channel" \
       "udp://239.0.70.2:5000?pkt_size=1316&ttl=1"

The original functions did not work correctly for edge pixels, e.g.
when CODEC_FLAG_EMU_EDGE is set, leading to corrupt output in e.g. VLC.

Recent gcc versions define __ARM_PCS or __ARM_PCS_VFP to indicate the
VFP ABI in use, and ARM RVCT defines __SOFTFP__ when using this ABI.
If none of these are defined, check $cross_prefix and $cc for the
substring "hardfloat", and finally fall back to a linker test.  This
gives the correct result in most configurations.
