[TESTING] Rhod AGPS (XTRA) support

[mbellot]

Missed yesterday, but ran navigation this morning and everything was flawless (minus the accuracy issues).

I had booted with GPS off, gave the system about a minute to try and lock with no luck so I rebooted with GPS on. It had lock within 10 seconds of rebooting and getting Maps loaded. I've downloaded the injector app so I don't have to do that any more.

Only problem (possibly unrelated) is shortly after stopping navigation the phone had a full blown SOD. /proc/last_kmsg will be in the OMGB thread since that's my base distro, but I looked and didn't see anything obvious.
