The posix layer implementations should work on QuRT.
QuRT needs to provide a way for getting the current time.

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.

px4_read, px4_write, and px4_opctl were not returning the correct
value on error. They were returning -errno vs -1.

this runs the mpu6000 200usec faster than requested then detects and
disccards duplicates by comparing accel values. This avoids a nasty
aliasing issue due to clock drift between the stm32 and mpu6000
this runs the sampling of the accelerometer 200usec faster than
requested and then throw away duplicates using the accelerometer
status register data ready bit. This avoids aliasing due to drift in
the stm32 clock compared to the lsm303d clock
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.

ld.gold does not support the -Ur flags and it seems some people have
ld as a link to ld.gold.
Made LD = ld.bfd to avoid confusion.

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.

The initialization functions were called after the script
commands were run causing a deadlock waiting for an

The build fails when modules override this flag with a larger value,
and this lower value is still checked. The new flag seems to be in
addition to the old flag, not a replacement.

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.
