Add support for AppleIR Remote as an input under Linux systems.
This requires Linux 2.6 with evdev and appleir drivers. The keymapping is done to mimics the one that was done for MacOSX. WARNING: Most distributions do not seems to bother and only let root access to the device. Modify udev rules accordingly if you want regular user to be able to use the remote. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@26795 b3059339-0415-0410-9bf9-f77b7e298cf2
