patch: xbmc and lirc

[Juergen Lock]

Hi!

 So the xbmc port atm doesn't build its lirc client code because
that code uses inotify() which is a Linuxism.  Today I took a closer
look and found it actually only uses inotify() to find out when
lircd is stopped, which at least on FreeBSD it will also find out
by receiving an eof from the socket fd so we can actually just
disable the inotify() code.  Did that, added an autoconf check
for good measure, and that got lirc working. :)

 I've put the patch here:

	http://people.freebsd.org/~nox/dvb/xbmc/patch-xbmc-lirc.txt

(the first hunk is actually redundant, instead you should just
remove files/patch-guilib__common__Makefile.in - I'll add the
patch without it at the end.)

 The mceusb remote works as is then with webcamd, for dvb tuner
remotes supported by the Linux code webcamd uses you can start
with this ~/.xbmc/userdata/Lircmap.xml :

	http://people.freebsd.org/~nox/dvb/xbmc/Lircmap.xml

note the comments at the beginning, you may need to remap
important buttons for your particular remote.  Also see here:

	http://wiki.xbmc.org/index.php?title=HOW-TO_setup_Lirc_to_talk_to_XBMC

 And here comes the patch.  Enjoy, :)
