When switching into Hold mode establish a Loiter around current position,
even if we were before already loitering (eg in Mission mode).

5s is a more reasobale time for tailsitters, which rely differently on this param
than other VTOL types. Tailsitters will ramp the pitch up withing this time,
while for other VTOLS types its only the max transitiont time.

This is now using the advanced lift drag plugin.
The important step was to enable airmode for yaw, otherwise yaw gets
saturated at low throttle and we can barely roll.
The other trick was to raise airspeed a little bit to avoid operating
too much at the lower end of throttle where control authority is low.

Before this the ESC calibration aborts if battery detection doesn't work.
The problem is if the user still connects the battery as he gets instructed
and the calibration aborts then the ESCs are in calibration mode and
after abortion calibrate to the wrong value.
Also I realized there's no additional safety by aborting the calibration
if the battery cannot be detected during the timeout because a pixhawk
board without power module will report a battery status from the
ADC driverand in it that no battery is connected which is the best
it can do. In this situation the motors will still spin if the
ESCs are powered.
Some ESCs e.g. Gaui enter the menu relatively quickly if the
signal is high for too long. To solve that it's kept high shorter.
Also all tested ESCs detect the low signal within a shorter time
so no need to wait longer.
- Change timings for a more reliable calibration.
- Make sure there's an error message when battery measurement is not
available also when it gets disabled after system boot in the power
just above the calibration button.
- Safety check if measured electrical current goes up after issuing the
high calibration value for the case the user did not unplug power
and the detection either fails or is not enforced.
This adds support for the TI LP5562 RGB LED driver.
Things to note:
- The driver is initialized in simple PWM mode using its internal clock,
for R,G,B, but not for W(hite).
- The chip doesn't have a WHO_AM_I or DEVICE_ID register to check.
Instead we read the W_CURRENT register that we're generally not using
and therefore doesn't get changed.
- The current is left at the default 17.5 mA but could be changed using
the command line argument.

The entire logic did not work for the case when the throttle channel is
reversed because then QGC sets trim = max for that channel and
the result is only half the throttle range.
set_vtol_transition_item sets the params of the mission item directly
to values that make sense for NAV_CMD_DO_VTOL_TRANSITION, but don't
for other NAV_CMDs. So make sure that whenever we use it, we then in
the next step reset the touched mission_item fields.

Transitions in Stabilized mode are done manually, the pilot controls the pitch angle
and if it's above the threshold the transition is declared finished (plus airspeed
check for front transition). Thus we can't have fixed thresholds but need to link
them to the actual max pitch angle in Stabilized mode.

We currently fuse 0 as airspeed rate measurement, and thus simply low-pass
filter the airspeed measurements. Testing has shown that the current default
on the airspeed rate measurement noise is set to low, and thus the airspeed
mesurement is filtered too much.

A VTOL plane in MC mode has no yaw setpoint during takeoff because of
weather-vane. To align for the front transition, the yaw target jumps
and caused a step in the controller, making it reach saturation.
With this commit, the previous yaw setpoint is set to the current yaw
when no yaw setpoint is sent in order to create a smooth yaw trajectory
starting at the current orientation when yaw target is suddenly finite.
The yawspeed filter also now contains the yaw speed instead of dyaw in
order to prevent chattering due to dt jitter.
