Adds a new exit/save menu that can be displayed at any time using the yaw-right stick command. Yaw-left still functions as "back".
Allows the user to save their settings even while nested deep in multiple menus. Previously the user was required to back up all the way to the top level menu to save or exit.
The logic did not support the switched 3D modes and would always set the throttle to `mid_rc`. This is appropriate for normal 3D mode, but for switched 3D modes this would lead to 50% throttle (either positive or negative depending on the switched mode settings).
Adds support to persist the RTC (if set) across the reboot if entering mass storage mode for on-board flash. The value is then used as the timestamp for the files exposed in the virtual FAT32 filesystem. The files will then have reasonable creation dates when copied to the host computer.
If the RTC is not set (or supported), then the default timestamp of 2018-01-01 will be used (unchanged from previous).
Included some improvements to the RTC functions and exposed the `tz_offsetMinutes` in the `timeConfig` PG. Support already existed for timezone offsets but the parameter wasn't exposed to the user and couldn't be set.
Move timezone offset up a layer as a parameter to systemResetToMsc()
Adds support for specifying a custom timezone offset from both the CLI and MSP calls to enter mass storage mode.
Added an option timezone offset minutes to the CLI `msc` command. If no parameter is specified then the default as specified by `timezone_offset_minutes` will be used. So to reboot into mass storage mode and force the file timestamps to be in UTC, use `msc 0`.
Added reboot message `MSP_REBOOT_MSC_UTC` to support rebooting into mass storage mode and forcing the timestamps to use UTC time (0 offset). The Configurator will need to be modified to use this message for operating systems that expect UTC times for FAT file systems (like Linux).
Previously the Throttle Position element calculation was based solely on the raw rcCommand value and didn't take into account the min_check deadzone so the resulting displayed percentage was incorrect. Also 3D trottle handling was not considered.
Corrected the calculation and added support for 3D throttle modes. Reversed thrust will be represented with negative throttle percentages.
The OSD stats provide no meaningful information and are just an annoyance when exiting these special states.
For Launch Control the stats will be displayed if the launch is triggered and normal flight occurrred.
If the quad is in an extreme orientation (like upside down) the transition to self-level modes can cause enough motion to trigger crash recovery. Added a 1 second delay during which crash recovery detection is blocked immediately after entering a self-level mode.
This also addresses an issue with GPS Rescue as when it activates it enables self-level. If in the above scenario this triggered a crash recovery detection then GPS Rescue would interpret this as a crash and immediately disarm.
