Enabled PDA GUI again, use --enable-pda. Question why was it disabled without notifying the maintainer? ????

- Fixed a compiler warning

* configure.ac: check for the xmlTextReader extension if libxml2 (required for skins2).

* configure.ac, NEWS: added mod and pva plugins.

- Make sure that lnb-lof1 and lnb-lof2 can be overriden by the commandline syntax frequency=xx:lnb-lof1=xx:lnb-lof2=xx
- Added value {A,a} to polarization=xx to force INVERSION_AUTO
- Sanatized a few error messages

    + No longer build a local libmpeg2 since it entered sid.
    + Build the livedotcom plugin.
  * toolbox:
    + No longer remove flac, speex and matroska from the woody build; I will
      provide clean backports.

    + Allow to use --enable-livedotcom without --with-livedotcom-tree so that
      we can use an installed version of libliveMedia et al.

    + Only activate the Matroska plugin if -lebml_pic or -lebml were found.

  duration for subs is stored in byte1 of the data packet and who
  directed me to the mkvtoolnix code.

           follow soon).

   (patch by Christof Baumgaertner)

* modules/gui/skins2/Modules.am: added missing file for make dist.

* ALL: I am a morron.

* modules/codec/ffmpeg/video.c: another fix for switching postproc on the fly.

* configure.ac: forgot one version number and added the aiff demux.

* ALL: bumped version number to 0.7.1 in preparation for the release.

Fail ./configure when ffmpeg/avcodec.h or postproc/postproc.h are not found and --disable-ffmpeg is not used.

- Always have a space between ";then" the configure script does not like this. It should be "; then" or better put "then" on the next line.
- Add a AC_ARG_ENABLE for cdda

  Though this still remains a hack. People should just use 'Open Disc' menu.
  I see no way to retrieve the original (non parition version) /dev entry,
  from the mounted drive.

 * pass bit per pixel info on to decoder

 * add 1 as fourcc for msrle

 * pass bit per pixel info to libavcodec (needed for msrle)

* modules/gui/wxwindows/open.cpp: cleanup.

 auto-detection.

* modules/demux/dts.c: more fixes.

* modules/audio_filter/converter/dtstospdif.c: cough cough.
