Now a variable belonging to a group can safely be constructed before the group it belongs to, and the group can be destroyed before its member variables. This greatly simplifies the AP_Var constructor(s).
Remove the lookup-by-index and lookup-by-key interfaces to AP_Var and replace them with first/next interfaces for all variables, and for variables belonging to a specific group. Document their usage. Add an accessor for the key associated with a variable so that search-by-key can be performed by a consumer. Throw away the lookup cache implementation, as it's not required anymore.
Re-layout the EEPROM variable header and tweak the EEPROM space allocator so that it's more resistant to interruptions during variable save.
Fix the global constants so that they work.
Add an interface for erasing all variables in EEPROM (only writes one byte).
Fix unit tests so that they work with the changed interfaces. Also tweak the unit test framework so that it doesn't inline all its code. This is a WIP - many more tests need to be written still.

Fix the comments around AP_Meta_class::meta_cast; they were leftovers from an earlier implementation and entirely not helpful.

Rather than implementing empty default constructors, make sure that AP_Var and friends have useful default constructors instead. This works around AP_Meta_class::meta_cast requiring a default constructor without having empty ctors scattered around.
Add accessors to AP_Var so that the global variable list can be traversed and the group/variable relationship comprehended by outsiders.

The format is a simple TLV format; a tag identifying the variable, a length for the variable, and then the actual data. This format could ultimately be extended to include waypoint/commands as well.
This allows us to load and save groups of variables to EEPROM without having to have a static EEPROM map.
Still needs unit tests and (probably) bugfixing.

Trim is now called again on pitch and roll, now that trimming can be done with adc_offsets. Fixed setup::motors for x frame.

no roll and pitch input means no change. Flicking will still update the throttle cruise value. Please check I have the signs correct!!!

This makes it possible to move one resistor on the APM board and feed it PPM directly from a receiver emitting a PPM stream.

- 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.

This can make re-opening a port faster (as the free/malloc pair can be avoided) and possibly more robust (in the case where e.g. the heap has been corrupted).
