Version 1.1.7

- Adapted VDR to the NEWSTRUCT driver. To use the new driver, compile VDR with
  'make NEWSTRUCT=1' (thanks to Holger Wächtler for some valuable advice).
  By default it currently still uses the old driver.
- Added some missing #includes (thanks to Martin Hammerschmid).
- Changed the log error message "can't record MPEG1!" to "error in data stream!",
  since the mentioning of MPEG1 has irritated many people.
- Consistently using malloc/free and new/delete (thanks to Andreas Schultz).
- Temporarily made cDevice::ProvidesCa() virtual (Andreas Schultz needs this
  in his DXR3 plugin).
- cDevice no longer exposes a file handle to cPlayer. A derived cPlayer class
  can now call DevicePoll() to see whether the replay device is ready for
  further data. A derived cDevice class must implement Poll() and shall
  check if any of its file handles is ready for data.
- Implemented several replay modes to allow players that play only audio (thanks
  to Stefan Huelswitt).
- Improved cCondVar::Wait() and implemented cCondVar::TimedWait() (thanks to
  Stefan Huelswitt).
- VDR no longer gives up if there is no DVB device. It continues to work if
  there is at least one device, either a DVB device found by the core VDR code
  itself, or a device implemented by a plugin.
