Remove boost::asio from plugin code (UAS breaking)

[vooon]

After removing asio from mavconn (#54) need to remove it from UAS and plugins.

[vooon]

List of plugins that use TimerService:

• sys_status
• param
• waypoint

[vooon]

Sys_status and waypoint done. Param require some refactoring.

[TSC21]

As said in #1041 from PX4 Firmware, CON goes down immediately when it enters position lock. Meaning that when it (the PX4) receives the first vision_estimate, the connection is lost. Till then it works ok!

@vooon OK, Libev seems to cause a slowdown too :(

I am streaming a message a 200Hz from PX4. On boost::asio I got the full 200 Hz rate, but with libev, it seems to get limited at ~160Hz

@mhkabir Can you show system load produced by ev_default_loop thread.

Use htop, F2 → Display Options → Show custom thread names.

@mhkabir does the connection is also lost when your Pixhawk enters position lock?

[mhkabir]

No, but I am not using tf messages, just PoseWithCovarianceStamped @ 200Hz
update.

Where the hell do you get a pose estimation at that rate? :D

Semi-direct visual odometry fused with IMU correction.

Using PTAM?
