px4_errx kills the process, so if possible we want to end the thread
but not the process. Using warnx and return exits gracefully.

The builtin commands all have _main suffix by convention so
no need to show _main. Also nsh calls the commmands without the
_main suffix.

If the topic has not been published, orb_copy returns a
negative number which causes update() to memset the data
contents to zero.
In some instances data is a null pointer. This causes a
segment violation crash.
Added a check for data != 0

When printing a uint64_t type using %llu, this works on a 32bit
system, but on a 64bit machine uint64_t is an unsigned long.
The compiler complains about unmatching types.
The time times in PX4 should likely have been unsigned long long
and not uint64_t as that type changes per architecture.

if termios.h is included before mathlib.h then BO is undefined.
Since mathlib.h is not needed it was removed but I still don't
know why this error occurs.
Also added -lrt to link flags for clock_gettime

Not yet functional. Full implementation will provide an IOCTL interface to
do bi-directional transfer. will model the interface after Linux.

Added more queue support to linux/px4_layer.
Use virt char devices for ms5611, and mavlink.
Added more HRT functionality. uORB latency test
now fails. Likely due to bad HRT impl for Linux.

The dataman module now works under linux using /tmp/dataman as the
file path. Two files from NuttX were added to the Linux impl for
single linked queue handling.

Modified uint32_t casts of pointers to unsigned long for portability.
It otherwise breaks on x86_64.
Added _PX4_IOC to handle the conflice between _IOC on Linux and NuttX.
Removed use of px4::ok() because it cannot be used in a thread based
implementation. Changed to use px4::AppMgr which uses ok() on ROS.
Removed up_cxxinitialize.c from Linux build.

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.
