LL_APPEND is called just before the loop spins up but various error conditions can cause the task to exit before then.
When that happens Mavlink::start_helper calls delete on the instance which tries to prune it from the global list.
If this is the first Mavlink instance to attempt starting the list head is null and we hardfault in the Mavlink dtor.
Only call LL_DELETE after checking the list head for a null pointer.
QuRT does not support UDP so moved the mavlink specific code
to a new file that is not built for the qurt target

The inclusion of px4.h requires C++ features not supported in the
Hexagon toolchain. The features are not required so the required
headers are used instead.

Most of the current POSIX builds will not use the UART and it
is just a unnecessary dependency to satisfy when running in a
test environment.

QuRT does not have a filesystem, so creating a virtual filesystem
that could be implemented as an in-memory file or a remote file
over fastRPC.

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

The latency_test used to pass an object pointer as argv which
won't work in the posix port because it expects argv to be a
null terminated array of character pointers (which it makes a
copy of).
The test was refactored to use a singleton pattern and avoid
having to pass the object pointer to the thread.

GCC was more picky about prototypes for inlines being required.
The generate_listener.py script used incorrect printf formats and
was casting %f params to float, but printf casts all %f params to
double per the spec.

There were some missed calls to open and ioctl that need to be
px4_open and px4_ioctl.
QuRT also does not provide usleep() so px4_time.h has to be included
in files calling usleep.

The unit test was not passing a null pointer terminated argv.
The posix port depends on argv being null terminated to
determine how may args were passed since PX4 API doesn't
pass argc when spawning a new task.

uORB was refactored in order to support the MuORB changes required
for QURT. Those changes wil be added in a subsequent commit.
The files are split out by posix and nuttx so the changes are visible.
When this has been tested, the files can be re-merged and re-tested.
