this will hopefully fix the NO_GPS problems that have been regularly
happening in recent months. I will watch the logs carefully to see if
the problem recurs
we need to reset the idle timer only on good data, or a call to
init(). Otherwise we never use it.

This makes PSTR() type safe by using a 1 byte wrapper
structure. Attempts to use the wrong varient of a print function will
generate a compilation error.

- disable NMEA autodetection; false positives are still a risk
- trim down the console output to a minimum; we still need something to help users diagnose potential problems, but the old output was much too verbose
- rather than block forever, only do one autodetect pass for each ::read call. That's still too long (five seconds or so) but better than blocking forever.
- don't block forever if no GPS is attached.

Added an init string for SiRF receivers that will bring them back out of the binary mode configuration that AP_GPS_Auto sets them to.
Picked up the GPS logging format from the AP_GPS_Auto test.

Major new features:
- No RAM buffer for the NMEA message being parsed; saves 120 bytes of RAM.
- More robust parser, a little less likely to be confused by bad messages.
- Added configuration strings for SiRF, ublox and MediaTek GPS in NMEA mode to select just the messages of interest.
Note that the issue that TinyGPS has with co-ordinates with "different" numbers of decimal digits is addressed in this code.
Size is comparable to the old parser.

Otherwise, we can end up settling on NMEA as a mode just after switching a SiRF GPS to binary mode.

Increase the no-data timeout to slightly more than a second, so that GPS' with a 1Hz update rate don't cause problems.

This should obsolete AP_GPS_HIL as it's a little more versatile (and it will generate cheaper code).

Nuke AP_GPS_IMU, as nothing is using it anymore.
Simplify the handling of no GPS/no fix detection.
Fix prototypes for ::init and ::read.
Update AP_GPS_Auto and corresponding example, nearly ready for primetime.
Use uint8_t rather than byte.
Strip some _error() calls to save space. More could still go.
