Calling serial::write() in quick succession was blowing away the previous buffer, fsync does not guarantee that data is transmitted on serial lines. On the other hand tcdrain waits until the output buffer is empty.
* usb: Added parameter to enable always starting mavlink on USB.
Refactored cdcacm_init into a module and added a paramter to allow always starting mavlink on
USB, also added a paramter to choose the mode. The current default behavior is to wait and listen
for data on USB and auto-detect the protocol (mavlink, nsh, ublox). This results in the mavlink
stream not starting until something else on the mavlink network sends a packet first. The new
default behavior is to always start mavlink.
Added parameters
MAV_USB_ENABLE -- default 1 (always start mavlink on USB)
MAV_USE_MODE -- default 3 (onboard)
* added 3 retries for opening serial port in mavlink, removed sleep before sercon
* added DRIVERS_CDCACM_AUTOSTART to ark-v6x default.px4board
* added CONFIG_DRIVERS_CDCACM_AUTOSTART=y to default.px4board for boards with CONFIG_CDCACM in their nsh/defconfig
* format
* remove PGA460 from COMMON_DISTANCE_SENSOR to save flash
* remove LIS2MDL from COMMON_MAGNETOMETER to save flash
* disable CONFIG_DRIVERS_CDCACM_AUTOSTART for fmu-v5 protected.px4board
* moved and renamed parameters, removed mode logic in mavlink
* changed parameter names, added mode none
* remove parameters from mavlink
* Added parameter UXRCE_DDS_SYNCC to enable system clock synchronization. Refactored and cleaned up. Only set system time if it's off by more than 5 seconds (same as mavlink and gps).
- new sensors work item that subscribes to N x sensor_gps and publishes vehicle_gps_position
- blending is now configurable with SENS_GPS_MASK and SENS_GPS_TAU

* parameter and logic to commander for triggering failsafe from external automatic trigger system.
* logic to startup script for enabling ATS. Added uORB publishing to pwm_input module.
* Refactored out CDev usage from pwm_input and ll40ls. Refactored out ll40ls specifics from pwm_input and cleaned up dead code.
* removed bus options that were essentially duplicates, causing hardfaults if attempting to start an already running driver. Changed NULL to nullptr. Removed bus options that were unused
* removed condition from if statement that was unnecessary
* fixed style
* We have RAM problems and can't afford 4 mavlink instances. This only adds logic the rc.board for the fmu-v4 that only has an effect for SYS_AUTOSTART = 4250 (TealOne airframe).
* added a parameter for enabled the smart battery
* start tel1 and tel2 at 921600 and max rate
* turned up the max tx rate on mavlink streams for telem1 and telem2
* turned off mavlink stream for tel1 in 4250_teal. This is connected to TX1 FTDI UART and has issues.
* moved check to 4250 board ID to start mpu9250s for Teal airframe into fmuv4 rc.board.
