Klaus Schmidinger 7e4b4d2905 Version 0.64
- NOTE: If you are using DVB driver version 0.7 you need to load the dvb.o
  module with option outstream=0, so your insmod statement should read
  'insmod dvb.o outstream=0'. This is currently necessary because 'vdr'
  still works with AV_PES data.
- Video files now have the 'group read' bit set.
- Fixed handling errors in 'readstring()'.
- Handling SIGPIPE and re-establishing handler after intercepting a signal.
- The configuration files are now by default read from the video directory.
  This can be changed by using the new '-c' option. Make sure you copy your
  current '*.conf' files to your video directory ('/video' by default), or
  use "-c ." to get the old behaviour of loading the configuration files
  from the current directory.
- Waiting for input is now handled by a common function, which improves
  response time on user actions. As a consequence the EIT data may sometimes
  not be displayed, but this will change later when cEIT runs as a separate
  thread.
- The new SVDRP command 'HITK' (thanks to Guido Fiala!) can be used to 'hit'
  a remote control key.  Establish an SVDRP connection and enter HITK without
  a parameter for a list of all valid key names.
- The new SVDRP command 'GRAB' (thanks to Guido Fiala!) can be used to grab
  the current frame and save it to a file.
- The new SVDRP commands 'OVL*' can be used to control video overlays (thanks
  to Guido Fiala!). This is mainly for use in the 'kvdr' tool (see the 'kvdr'
  page at http://www.s.netic.de/gfiala).
- If the name of the video directory used with the '-v' option had trailing
  slashes, the recording file names have been damaged. Trailing slashes are
  now silently removed.
- Fixed a buffer overflow in EIT parsing.
- Added a security warning regarding SVDRP to the INSTALL file.
- Fixed 'confirm' dialog.
- The daemon mode (option '-d') now no longer works with REMOTE=KBD (there
  is no stdin in daemon mode, so KBD makes no sense - plus it sometimes
  crashed).
