Andrew Tridgell 79acaeaef1 AP_Scheduler: cope with high CPU load by stretching loop times 
this adds an extra budget of time per loop when we are not achieving
scheduled tasks at a rate of at least 1/8 of the desired rate. This
fixes an issue where a vehicle can become uncontrollable if the user
asks for a SCHED_LOOP_RATE which is not achievable. As these events
happen we add extra loop budget until we are able to run all tasks. We
drop the extra time when the CPU pressure eases.

Andrew Tridgell b3ed8fd3f9 AP_Scheduler: scale perf_info with loop rate

Andrew Tridgell 8b0e9bcff4 AP_Scheduler: use pre-computed loop constants 
this prevents changing the loop rate without a reboot. Too many
subsystems rely on a consistent loop rate to allow it to be changed

Andrew Tridgell 44dd079cb9 AP_Scheduler: allow for loop rates above 400Hz 
with ChibiOS we can run copter at 1KHz with no scheduling misses. This
small PR allows that to be configured.

Andrew Tridgell 580af4a69a AP_Scheduler: removed create() method for objects 
See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach

Thanks to assistance from Lucas, Peter and Francisco
