Raspbmc patches



Hi,

this is a forward port of the relevant XBMC patches that http://svn.stmlabs.com/svn/raspbmc/patches/XBMC-hardfp/patch_xbmc.sh applies.

The following could be sent upstream:

- the Lircmap.xml part of remote.patch (I'm making a pull request soon)

- perhaps the fixCPU.patch, but I don't understand xbmc enough to really see what's going on.
