Pavel Kirienko 2b2c307eac Performance audit (intentionally duplicates #6829) (#6847) 
* UAVCAN ESC output: removing ESC output channels from published message that are always zero. This allows the UAVCAN stack to always transfer only the minimum number of output values, avoiding redundant zeroes and the associated increase in bus load and CPU time

* Added a separate mixer file for CAN quadrotor

* Sampling profiler improvements

* PMSP: Output more endpoints

* Matrix update

* libc usage workaround

* Removed UAVCAN perfcounters

* Matrix submodule update

px4dev d90345a166 Some early gdb/Python macros for working with NuttX. 
Note; only tested with gdb 7.6. Will definitely not work with the stock PX4 toolchain's gdb.
