If the hardware support RESET lockout that has nArmed ANDed with VBUS
vbus_sense may drop during a param save which uses
BOARD_INDICATE_EXTERNAL_LOCKOUT_STATE to prevent external resets
while writing the params. If we are not armed and nARMRED is low
we are in such a lock out so ignore changes on VBUS_SENSE during this
time.
The stackcheck build flash space overflows after adding hygrometers.
Also follow the naming convention of other similar config flags, and rename the
config.

This goes the other way around; arch_io_pins is using the pin
definitions from drivers_board, so the drivers_board needs to be linked
into arch_io_pins

This adds the env option PX4_FUZZ which runs the LLVM libFuzzer which
throws random bytes at mavlink_receiver using MAVLink messages over UDP.
The MAVLink messages that are being sent are valid, so the CRC is
calculated but the payload and msgid, etc. are generally garbage, unless
the fuzzing gets a msgid right by chance.
As I understand it, libFuzzer watches the test coverage and will try to
execute as much of the code as possible.
This enables flow control on CDCACM for the NuttX boards which fixes a
problem where HITL would stall.
The stall could happen if the hardware would be a bit too slow in
keeping up with the incoming messages. Often, this happened on arming
because the logger would take some time to log all parameters right at
the beginning.
The stall would then not recover due to NuttX bug where the rx interrupt
would not be restored correctly and instead only a slower watchdog would
release the next read. This watchdog takes 200ms which means it's hard
to impossible to get out of the situation without restarting sim and/or
PX4. For more information about the issue, see:
apache/incubator-nuttx#3633
As a workaround, until that bug is fixed, and because it makes sense
anyway, I propose to enable FLOWCONTROL for the serial via USB.
