It makes more sense to set the optimization flags on a platform basis
instead of individually for each module. This allows for different
optimization options for SITL, NuttX, Snapdragon, etc.
- voting is now at a central place instead of duplicated within the
estimators
-> this also means that estimators that did not do voting so far,
now have voting, like ekf2
- estimators requiring more than that can still subscribe to the raw
sensors
- allows sensors_combined to be 3 times smaller
- reduces logger, memcpy (cache) & RAM overhead
- all modules requiring only 1 or 2 sensor values now automatically get
the voted result
- this also adds voting to baro
The existing orb_advert_t use thoughout the code sometimes tries
to treat it as a file descriptor and there are checks for < 0
and ::close calls on orb_advert_t types which is an invalid use
of an object pointer, which is what orb_advert_t really is.
Initially I had changed the -1 initializations to 0 but it was
suggested that this should be nullptr. That was a good recommendation
but the definition of orb_advert_t had to change to void * because
you cannot initialize a uintptr_t as nullptr.

The calls to orb_advertise were being mishandled throughout the code.
There were ::close() calls on memory pointers, there were checks
against < 0 when it is a pointer to a object and values larger than
0x7ffffffff are valid. Some places orb_advert_t variables were
being initialized as 0 other places as -1.
The orb_advert_t type was changed to uintptr_t so the pointer value
would not be wrapped as a negative number. This was causing a failure
on ARM.
Tests for < 0 were changed to == 0 since a null pointer is the valid
representation for error, or uninitialized.

The calls to task_spawn_cmd, kill_all, and systemreset were wrappers
around the px4_{task_spawn_cmd|kill_all|systemreset} implementations.
Removed the wrappers and changed all calls to the px4_ equivalents.
NuttX specific code was moved into px4_tasks.h

Keep existing API use in code. Bind the use of the OS independent
implementation in the systemlib layer.

Calls to task_delete and task_spawn_cmd are now
px4_task_delete and px4_task_spawn_cmd respectively.
The px4_tasks.h header was added to the affected files
and incusions of nuttx/config.h were removed.

Moved satellite info from vehicle_gps_position_s into a new uORB topic
satellite_info.
Renamed satellites_visible to satellites_used to reflect true content.
sdlog2 will log info for GPS satellites only for now.
