Revert "HIL: Increased MAVLink link wait time based on previous experience that this is timing sensitive."

This reverts commit 78bf7ed9.

Reduce data manager SD card wear and tear

When the data manager was first designed each file record contained a 2
byte header and an 126 byte data section, resulting in a record length
of 128 bytes. Along the way it was decided to add 2 spare bytes to the
record header, but regrettably the data section was not correspondingly
reduced in size so we end up with a record length of 130 bytes. This is
bad since it does not align with SD card flash sectors and results in
more erase/write flash cycles than necessary thus reducing the SD cards
life.

This update reduced the data section of the data manager to 124,
resulting in an optimal record length of 128 bytes.

In order to avoid the reuse of data previously written data in the old
format, which could result in catastrophic misinterpretation, the data
manager file is checked at startup. If it is found to be in the old
format, it is deleted and recreated with in the new record length. In
this case previously stored data is lost, but that is far safer than the
unpredictable result of using the old file.

fix mission topic bug, clearer naming

Fixed blinkm state indication (was not properly reporting flight mode).  Added flashing orange safety disarmed state indicator and solid blue failsafe indicator. Changed safety on state to solid cyan.  Increased LiPo cellcount support to 6.

Hotfix to PX4IO uploader. There are no known mishaps due to it, but very clearly the IO firmware flashing process should be verified after an upload.

startup: cleanup of cox mixer files (Thanks Rune)

Added a -w option to mavlink, added vicon messages to stream.

Untangled local pos and distance messages, now sending distance messages only for actual distance measuring devices

mavlink: Change to size optimization

mavlink: Updated protocol files
