Simon Dawson 6b6255bf94 gpsd: backport upstream patches pending 3.11 release
The 3.11 release of gpsd is imminent; in the meantime, backport some patches
from upstream to fix some of the autobuild failures.

Also bump to the most recent Git snapshot.

When nmea is False and ncurses support is enabled, the build fails as
follows.
gpsmon.o: In function `gpsmon_hook':
gpsmon.c:(.text+0x974): undefined reference to `driver_nmea0183'
collect2: error: ld returned 1 exit status
scons: *** [gpsmon] Error 1
scons: building terminated because of errors.
The problem appears to be a failure to protect use of the driver_nmea0183
variable with appropriate #ifdef guards.
