Subject: gps: gpsd: Adding gpsd_iface to interface with gpsd.

The gpsd_iface class might be useful for more than just e3x0,
it therefore belongs into lib/usrp instead of lib/usrp/e300.

A new UHD component is being registered, to cope with the additional
dependency. If libgps is not found, UHD and E300 will be compiled
without GPS support.

This has several consequences:
- The E310 GPSDO should now work transparently over network
- Users can use the GPS through gpsd for other applications
  *while* running UHD applications
- We now have a dependency on libgps

We need currently at least version 3.11 (while running 3.14),
on the device. Older versions do work if 3.10 runs on both
sides e.g
