Lucas De Marchi f7b453359d AP_Baro: MS56XX: convert to threaded bus 
This converts MS56XX to use the thread started by SPI/I2C instead of
using the timer thread. This also fixes a possible starvation of the
main thread:

    1) INS driver registers itself to be sampled on timer thread
    2) MS56XX registers itself to be sampled on timer thread
    3) Main thread waits for a sample from INS with
       ins.wait_for_sample()
    4) timer thread is waiting on update from MS56XX and consequently
       the main thread is waiting on an I2C/SPI transfer

Besides this starvation there's another one due to reuse of the timer
lock in order to pump values from the timer thread to the main thread. A
call to the update() method when we have a sample available would need
to wait on any other driver holding the timer lock.

Now there's a lock just to pass the new values from the bus thread to
the main thread with a very tiny critical region, not waiting on any
bus transfers and/or syscalls.

How To Get Involved

The ArduPilot project is open source and we encourage participation and code contributions: guidelines for contributors to the ardupilot codebase

We have an active group of Beta Testers especially for ArduCopter to help us find bugs: release procedures

Desired Enhancements and Bugs can be posted to the issues list.

Helping other users with log analysis on http://discuss.ardupilot.org/ is always appreciated:

There is a group of wiki editors as well in case documentation is your thing: ardu-wiki-editors@googlegroups.com

Developer discussions occur on drones-discuss@google-groups.com
