Fixed CMakeLists.txt to be consistent with module.mk
Converted PX4_TICKS_PER_SEC to define for QURT to get around relocation error
Added stubs for QURT so building a full executable can be tested. This will
enable CI testing without the full Hexagon SDK.

Created a dummy build_git_version.h so I did not have to figure out
how to generate it.

Commented out topic_listener.cpp from src/systemcmds/CMakeLists.txt
because it depends on a generated cpp file.

Link doesn't work mut many modules build

-uORB, sdlog2, vtol_att_control, ekf_att_pos_estimator

-add -Qunused-arguments for clang
-update to a recent cmake
-comment unused variables

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.

Added launchfile to launch gazebo iris and mavros bridge. Added sitl_gazebo to makefile and new init rc file for gazebo iris apps and params

Moved nuttx specific make rules to files in makefiles/nuttx.

All target specific makefiles are in their target sub directories.

To minimize file duplication, targets that share rules include a
common file. For example the posix and posix-arm targets both use
makefiles/posix/posix_elf.mk

The SITL build is now the default posix build.

The linker script for posix was moved to makefiles/posix.
The rc.S file was moved to posix-configs/SITL/init/
The POSIXTEST board definition is now SITL

To run the SITL test run:

make sitlrun

This replaces the make posixrun target.

The build directory is now Build/posix_sitl.build/

The toolchain_* files are target OS specific so they were moved to
the target OS subdir.

The gcc_version.* files are only cleared once per make instantiation so
a build that creates multiple HW targets will try to link with an
incompatible .o file (i.e. x86 build linking ARM .o).  I created
posix-arm as a separate target to fix this problem.

The Build/git_version.d and Build/git_version.o files need to be
removed on each make to prevent confusion from a previously
generated dependency file for a different target.

The Build/git_version.* files need to be removed on make clean.

When make is invoked as "make posix posix_default"
it will build the posix_default target twice. The Makefile was
fixed to correct this.

If "make posix" is run, the Makefile still calls "make PX4_TARGET_OS=posix".

If "make posix posix_default" is run, the posix target just exports
PX4_TARGET_OS=posix and then make evaluates the next goal (posix_default).

NuttX is still the default target and all NuttX configs can still
be built with:

make

Individual NuttX, POSIX, and QuRT configs can now be built more
easily by specifying the target and configs:

make posix posix_default
make qurt qurt_hello
make nuttx aerocore_default

Running make with just the target will make all the configs for
that target:

make nuttx
make qurt
make posix

The help is also target specific:
make nuttx help
make qurt help
make posix help

"make help" will still assume you want help for the NuttX target

Added a new QuRT config called qurt_hello as a sample config to
test buiding in different commands for separate configs.
