Added missing functions that were added for other targets but not for qurt.

Added workaround for missing sem_timedwait(). This may have a performance
impact until a sem_timedwait is supported.

std::to_string is not supported by the hexagon compiler

Workaround required Eigen downgrade to 3.2. Hexagon toolchain does
not support C++11 features of newest version of Eigen.

Running make qurt_fixup will downgrade and patch Eigen for qurt.
Running make restore will revert the patch and do a git submodule update
to restore the expected Eigen version.

Added a "restore" target to undo qurt_fixup

Before doing a qurt build run:

    make qurt_fixup

That will downgrade Eigen to 3.2 and apply the require patch.
To build another target after downgrading:

    make restore

Them make the desired target (other than qurt).

Fixed type used in orb_priority to be consistent with the code
(int* was used in declaration but int32_t* used in code)

Removed unused class member variable in sensors.cpp

Added cmake fix for unit tests. The location of px4_log.c changed.

Fixed the qurt drv_hrt.c implementation to use us instead of ms for time resolution

Added px4_led.c to nuttx platform layer
Use the posix version of px4_led.c for nuttx so we don't end up with
duplicate files. It was moved out of common because it is not used by qurt.

Changed PX4_DEBUG to PX4_WARN when checking for the error condition for store_poll_waiter in vdev.cpp

Updated the px4_log.h file to make calls to the qurt_log functions.
The qurt_log function is defined in the platforms/qurt layer.

Added an option to control starting the commander module in HIL mode.

Moved the flight specific drivers to the configuration file instead of adding them
to the common tool chain file because HIL mode does not need them.

Added the uorb Subscriber and Publisher classes

Call PX4_ISFINITE macro instead of isfinite().

Added px4_led.c to nuttx platform layer
Use the posix version of px4_led.c for nuttx so we don't end up with duplicate files.
It was moved out of common because it is not used by qurt.

Changes to support QuRT intrgration with DSPAL and
move from simulator to real HW.

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

QuRT's pthread_cancel implementation is lacking, and causes px4_poll to
always wait for the maximumn timeout. A cleaner implementation is provided
that uses the HRT work queue for posix targets.

In the future the posix code should be rtefactiored so that qurt (and other)
implementations that are duplicated, use the posix implementation.

There is a race condition for the accel and mag polling rates.
Whichever one gets set first, the other will be uninitialized.

Set the mag polling rate to 1ms if uninitilized.

The workqueues measure time in ticks  which is typically 10ms.
Some interrupt events in Nuttx occur at about 1ms so a more
granular workqueue is needed for POSIX.

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 HRT call processing normally happens via HW timer interrupt
handler. Since the POSIX port has no ISR handling, the HP work
queue is used.

Instead of irq_save() and irq_restore() calls to disable/enable
interrupts, a mutex is used to protect each queue.

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.

this keeps it small enough to fit in a float, which makes it possible

this device ID identifies a specific device via the tuple of (bus, bus
type, address, devtype). This allows device specific configuration
data to be stored along with a device ID, so the code can know when
the user has changed device configuration (such as removing an
external compass), and either invalidate the device configuration or
force the user to re-calibrate

this allows drivers to register generic device names for a device
class, with automatic class instance handling

Add direct-access methods to the base Device class, so that there's a common way of talking to drivers regardless of which of the specialised classes they derive from.

Make the Device destructor public and virtual, so that arbitrary devices can be deleted. Likewise for classes that derive from it.

Make Device::init public so that arbitrary devices can be initialised after being returned by factories.

Make it possible to run fmu and px4io simultaneously with full control over both sets of possible PWM outputs.  First started wins.
