The list_tasks and list_devices commands will show
lists of running px4 threads and created virtual device nodes.
The list_builtins command was removes and the list of commands
will be shown if return is pressed.

The getopt command uses global variables and is not thread safe.
Created a minimal px4_getopt version that supports options with
or without an arg, and random placement of options on the command line.
This version modifies the order of the args in argv as does the
POSIX version of getopt.
This assumes that argv[0] is the program name. Nuttx may not support
that properly in task_spawn.

The simulator satisfies the dependencies for an accelerometer
being present.
The accel code compiles but is not fully functional.

The simulated device satisfies the factory pattern used by
MS5611 to create a specific I2C or SPI device instance.
For now the functions just return true, but should/could
return simulated data.

Added PX4_ISFINITE(x) to px4_defines.h to handle the differences on
NuttX and Linux.
This change also picked up some file renaming for virtual character devices

Disabled gcc warnings that are tripped by Eigen.
Removed signal code that is not needed in Linux port and was
causing gcc warnings.

PX4 uses NuttX data structures throughout so those data structures
were preserved and used to implement high and low priority queues.
A unit test for the work queues was added.
The polling rate of the queues are set in px4_config.h in
CONFIG_SCHED_WORKPERIOD. The units are milliseconds.

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.

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

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.

Uncomment the following line in setup.mk and comment out the line above
to enable the Linux build.
export PX4_TARGET_OS = linux
The build uses the clang compiler by default. The final bundled executable
is mainapp located in:
Build/linux_default.build/mainapp
When you run mainapp it will provide a list of the built-in apps. You can
type in the commands to run such as:
hello_main start
Because the Linux build is threaded and does not support tasks or processes,
it cannot call errx, exit() _exit(), etc. It also requires unique scoped
variables to test if a thread is running or if an application should exit.
The px4::AppMgr class was added in px4_app.h for this purpose. The
hello sample app demonstrates how this is used.
