Fix a multiple include. The += adds a new item to the list, whereas *= only
adds it if it is not already present.
Replace all INCLUDEPATH += $$PWD by INCLUDEPATH *= $$PWD
Added another INCLUDEPATH that was being pulled in multiple times in the
plugins.
Changed all remaining INCLUDEPATH += to INCLUDEPATH *=
Tells the doxygen preprocessor to ignore __attribute__() strings.
Convert board to body rotation to a proper inverse Tait-Bryan.
Changed Rbs-->Rsb in order to reflect the fact that the orientation matrix
has changed sense.
Add calibration class support for computing yaw orientation.
Connected yaw orientation UI elements to calibration class.
Indoor INS: do not perform correction at 500 hz

Indoor mode right now is a CPU beast because it performs the
correction step every cycle.  This changes it to run as frequently
as it would if the GPS were available.
Some windows wget are having trouble with --trust-server-name, so
removing from gtest as is not necessary.
Improved GUI layout, text, and tooltips.
Added support for M25P16 flash chip

posix: bump up telemetry rx/tx buffer sizes to work around deadlock

pios_tcp.c performs all transmits synchronously in the tx_start
handler.  This can lead to deadlocks on the telemetry connection->lock.

Rx thread takes connection lock, calls tx path in response to a get
request.  Blocks on full tx queue.  Tx thread blocks on connection
lock.  Deadlock.

This change does not actually fix the issue.  It simply works around
this deadlock by making the tx buffers larger.
