valgrind-1.0pre3-dvb.patch enables checking correct usage
of the the Linux DVB API ioctls with valgrind
(http://developer.kde.org/~sewardj/). Or, more to the point,
it allows you to check your DVB software with valgrind
without getting all those "unknown ioctl" warnings.

Notes:
- only frontend and demux ioctls are currently implemented
- some ioctls take structs as arguments; due to padding, valgrind
  will complain about uninitialized data passed to the ioctl unless
  you memset() the whole struct to some defined value
