means this task only needs 800 bytes (of which only 120 is for the WMM). Free
heap is now 9k.

enough memory. Increase task memory a little. I'm not sure that it's possible
to make the WMM memory usage less.

This creates a new UAVObject called GPSSatellites to hold
information about which satellites the GPS receiver can see
and the quality of their signals.
NMEA GSV sentences are now parsed. The full set of GSV data
may be split across multiple GSV sentences, each containing
info for at most 4 satellites. Once an entire set of GSV
records has been collected, the GPSSatellites UAVObject is
updated.

Remove asserts on bad data, only assert on coding errors.
Remove unnecessary inline qualifier to reduce code size.
Handle more lat/lon precisions in conversion to fixed-point.

GPS module now updates GPSPosition UAVObject
rather than the PositionActual object. The
GPSPosition object is intended to be consumed
only by the AHRS. The AHRS will use this (and
other inputs) to compute a filtered version of
the position in the PositionActual object.
This commit will cause temporary breakage of the
GPS functionality in the GCS until the PositionActual
object is properly updated by the AHRS. Most of the
GCS should continue to use PositionActual. The only
exception to this might be any tool for specifically
visualizing the raw GPS state.
GPS.c is now only responsible for receiving a
complete NMEA sentence from the COM interface.
NMEA parsing is now factored out into NMEA.[ch]
which is where GPSPosition is now updated based
on the complete NMEA sentences obtained from the
GPS.
Latitude and Longitude are now encoded in a
fixed-point notation in units of degrees x 10^-7
to prevent truncation of precision due to encoding
into a float.

1. Added reenumeration function and call it on USB init (device will appear after reprogramming now)
2. Moved buffer.c to general flight/Libraries location
3. Removed the 62 byte transmission limitation by adding a transmission buffer
4. Sped up USB communication by increasing endpoint polling frequency
Note, that the nonblocking and blocking USB send functions are not blocking entirely correcting. The blocking calls the nonblocking, and the nonblocking blocks until the last chunk has started tranmission if it's a big transmission. The buffering I added would generalize to non-blocking nicely, but would require using the EP1(IN) callback to handle most of the tranmission. This creates a lot of issues if one function is pushing data onto the buffer and the interrupt is sending.

- Created a pluggable COM layer
- Converted COM + USART init into static initializers
rather than typedefs
- Generalized the USB HID COM API to match the USART
API.
- Changed USART and COM layers to be data driven rather
than #ifdef'ing/switching on the specifics of each port

nmeaProcess was attempting to null-terminate the
NMEA sentence but was not considering that the
preceeding loop may have looped beyond the end
of the packet buffer.
