A high rate workqueue is required that acts like an interrupt handler
for a HW timer.

The baro was not fully initialized when the sensors module tried to
open it. Added a sleep command and a sleep 2 to rc.S so the baro
is initialized by the time the sensors module tried to read it.

Fixed other noisy errors

When px4_getpid() was called from the shell, there was no opaque
thread ID to return. Added a special thread ID for the shell
context. This ID only works for px4_getpid() and cannot be used
for other px4_task_*() calls.

Nuttx complains about an unresolved _impure_ptr at link time.
This is a known issue when using STL templates in NuttX on ARM.

Created new ORBMap and ORBSet classes for NuttX.

Needed to ifdef SITL functionality not supoprted in NuttX build.

clean up mavlink network capability

The posix build only has one process so calling getpid() will not
provide the expected result.

QuRT doesn't support unlink and does not provide getpid().
The DSPAL layer provides access to usleep so an implementation is
no longer needed.

- subscribe to actuator controls after topic has been advertised

The toolchain_* files are target OS specific so they were moved to
the target OS subdir.

The gcc_version.* files are only cleared once per make instantiation so
a build that creates multiple HW targets will try to link with an
incompatible .o file (i.e. x86 build linking ARM .o).  I created
posix-arm as a separate target to fix this problem.

Use:

    mavlink start -u portnum

to set the UDP port.

Signed-off-by: Mark Charlebois <charlebm@gmail.com>

Usage is: -d udp[:<port>] If no port is specified, default port is
set to 14556. If -d isn’t specified then default is serial.

This adds support for a dynamic build for QuRT and initial
Multi-uORB changes to enable communication between the DSP and
the application processor.

This part of the changes do not affect the POSIX build. This is
enablement for the QuRT build using Multi-uORB. The second part
of the changes will be added in a new module under src/modules.

Some changes were needed to use the simulator and the UART for rc control.

Signed-off-by: Mark Charlebois <charlebm@gmail.com>

- added option to stream messages over udp
- still hardcoded stuff (port)

- wait for first message from jMAVSim
  before sending data
- publish raw rc data coming from PIXHAWK (temporary)
- send some interesting messages to jMAVSim
- prepare sensor data for sim drivers to read

Removed extra carriage returns in output strings
