Display progress for individual mission items

[nexton-winjeel]

A proposed change in MAVLink adds mission item progress to the MISSION_CURRENT message: mavlink/mavlink#2029

This PR adds support for displaying this information on the FlyView map:

Associated ArduPilot PR: ArduPilot/ardupilot#25249

NOTE: This PR won't build as-is, because it doesn't include the changes to the MISSION_CURRENT message definition.

This is really cool, thanks.

I think we should wait until the correspondent commits in mavlink and Ardupilot are approved, so we can update mavlink right away and make it work.

I haven't taken a deep look, but I noticed a typo in src/MissionManager/SimpleMissionItem.cc, "altitide" instead of "altitude".

Would you mind pinging me again when the PRs get merged in mavlink and autopilot to look into this again? Thanks!

Agreed. The consensus on the ArduPilot side is that this capability applies to more than just mission items, so will require a new message rather than an extension to MISSION_CURRENT.

Yep, thanks for that. I've fixed it, I just haven't pushed it because I know the builds will fail.

Will do. Thanks!

Thanks! This is a great addition.

You can reopen this once it's dependent parts (mavlink, ...) get completed.
