Add begin write and end write hints. If implemented by the serial
driver, then the driver can buffer up data sent via serialWrite() and
flush it when serialEndWrite() is called.
Implemented at the buffer level as it requires the least change to how
serial_msp and serial_cli are architected.
Also tidy up the visibility in the VCP driver.

This bulks up the writes and lets the USB VCP driver send one 20 byte
frame instead of 20 one byte frames. This speeds up the blackbox
download and makes VCP much more reliable when running under a virtual
machine.

Implement G-Tune for all PID controllers

during copter is disarmed.
Update PID controller and G-Tune documentation
- Added failsafe flightmode and rc control box.
To make failsafe procedure a separate flight mode and make it possible
to trigger failsafe with an AUX switch.
- Failsafe mode is activated when failsafe is active.
RC link lost is simulated with the failsafe AUX switch.
When NOT armed: failsafe switch to failsafe mode is shown in GUI (mode
tab).
- Activate failsafe mode with AUX switch.
- Prevent arming when failsafe via AUX switch is active (safety issue).
- Make failsafe disarm if motors armed and throttle was LOW (2D & 3D)
for `failsafe_throttle_low_delay` time (__JustDisarmEvent__).
Applied code changes to effectively add pull request: Make failsafe
disarm if motors armed and throttle low #717.
- Use failsafeIsMonitoring() to actually start monitoring.
- Added `failsafe_kill_switch` to code.
When set to 1 (0 is default), the failsafe switch will instantly disarm
(__KillswitchEvent__) instead of executing the landings procedure.
Arming is NOT locked after
this, so the craft could be re-armed if needed.
This is intended for racing quads where damage and danger must be
minimized in case of a pilot error.
- Added `failsafe_throttle_low_delay`, adapted documentation.
Used to adjust the time throttle level must have been LOW
to _only disarm_ instead of _full failsafe procedure_
(__JustDisarmEvent__).
- Updated the failsafe documentation.
- Re-enable arming at end of failsafe procedure.
At the end of a handled failsafe event, that means: auto-landing,
__JustDisarmEvent__ or __KillswitchEvent__, the RX link is monitored for
valid data.
Monitoring is a part of the failsafe handling, which means the craft is
still in failsafe mode while this is done.
Arming is re-enabled (allowed) when there is a valid RX link for more
then XX seconds, where XX depends on the handled event like this:
1. XX = 30 seconds after auto landing.
2. XX = 3 seconds after __JustDisarmEvent__.
3. XX = 0 seconds after __KillswitchEvent__.
NOTE: When armed via an AUX switch, you will have to switch to the
disarmed position at the very end to be able to re-arm.
The failsafe mode will not end until you do.
- __KillswitchEvent__ has now priority over __JustDisarmEvent__
- Apply rxfail values instantly when failsafe switch is ON
- Added missing cases to display.c
Show M when failsafe is monitoring for RX recovery (AND disarming when
armed with a switch).
===
Reworked the code from counter-based to time-based.
- AUX failsafe switch now has identical behavior to RX loss.
- Added RX failure and RX recovery timing.
- __KillswitchEvent__ skips RX failure detection delay (direct disarm).
===
[UNIT TESTS]
Adapted failsafe related unittests from counter-based to time-based
- Added failsafeOnValidDataFailed() to some tests
- Removed duplicate test setup from rc_controls_unittest.cc
- Removed magic numbers from rx_ranges_unittest.cc and rx_rx_unittest.cc
- Reworked all test-cases for flight_failsafe_unittest.cc
On bad (out-of-range) pulses; ROLL, PITCH, YAW will go to `mid_rc` and
THROTTLE will go to `rx_min_usec` (to `mid_rc` for 3D mode). So these
channels will no longer be set by the user directly.
Fallback values for the aux switches (0 .. max) can be set with this
version. Since these switches may trigger all kind of things, the user
needs control over them in case of a RX failsafe event.
A single flight control channel failure (first 4) when using parallel
PWM is interpreted as a failure for all flight control channels (first
4), since the craft may be uncontrollable when one channel is down. (+4
