Version 1.7.1vdr-1.7.1

- Adapted the tuning code to the new DVBFE_SET_DELSYS API (thanks to Reinhard Nissl).
  VDR now uses the driver from http://jusst.de/hg/multiproto_plus.
- Updated the Italian OSD texts (thanks to Diego Pierotto).
- Removed obsolete $(NCURSESLIB) from the Makefile.
- Implemented handling the standard component descriptor for AC3 (stream=4), as it
  will soon be used by the German ARD channels (thanks to Michael Pennewiß for
  advance information about this change). The previously used "Premiere pseudo
  standard" (stream=2, type=5) still works, but has apparently been wrongfully used
  by broadcasters from the beginning.
- Added missing description of the 'S' channel parameter to vdr.5 (reported by
  Reinhard Nissl).
- The SVDRP signon message now indicates the character encoding in use, as in
  "220 video SVDRP VideoDiskRecorder 1.7.1; Fri May  2 16:17:10 2008; ISO-8859-1".
  This may be useful for instance for external tools that provide EPG data, so that
  they can correctly encode the strings.
- No longer calling FcFini() to avoid problems with older (broken) versions of
  fontconfig (suggested by Edgar Toernig).
- Removed the compile time option VFAT to allow users of precompiled binary
  distributions to have full control over whether or not to use the --vfat option
  at runtime (suggested by Michael Nork).
- First step towards switching to TS (Transport Stream) as recording format:
  + The new function cDevice::PlayTs() is used to play TS packets.
  + The new functions cDevice::PlayTsVideo() and cDevice::PlayTsAudio()
    are used to play video and audio TS packets, respectively.
  + The new function cAudio::PlayTs() is used to play audio TS packets.
  + The new class cPatPmtGenerator is used to generate a PAT/PMT pair that precedes
    the TS data in Transfer Mode.
  + The new class cPatPmtParser is used by cDevice to parse the PAT/PMT data in a
    TS in order to find out which streams it contains.
  + The new class cTsToPes is used to convert TS packets to a PES packet.
  + cTransfer no longer uses cRemux, and doesn't run a separate thread any more.
    It just generates a PAT/PMT and sends all received TS packets to the primary
    device's PlayTs().
  + Live subtitle display no longer uses a ring buffer and separate thread.
  + cPesAssembler has been removed. Old VDR recordings only contain complete PES
    packets.
  + Since a TS needs to have a PAT/PMT, which requires the video stream type to
    be explicitly given, the format of the VPID field in the channels.conf file
    and the SVDRP commands NEWC/MODC/LSTC has been extended. The video stream type
    now follows the VPID and optional PPID, separated by an '=' sign.
- Updated the sources.conf file (thanks to Oleg Roitburd).
- Fixed a possible integer overflow in GetAbsTime() (thanks to Alexander Rieger).
- Fixed a problem with calling isyslog() from within the SignalHandler() (thanks
  to Udo Richter).
- Replaced the Finnish language code "smi" with "suo" (thanks to Rolf Ahrenberg).
- Fixed wrong value for TableIdBAT in libsi/si.h (thanks to Winfried Köhler).
- Errors in config files no longer keep VDR from starting.
- Removed unneeded include files <linux/dvb/dmx.h> und <time.h> from remux.h
  (reported by Tobias Grimm).
