If __px4_log_level_current is unsigned then the runtime filter
comparison warns because an unsigned value can't be less than zero.
Changed typed to signed so compiler will not issue a warning.

px4_log.c was added to px4_platform library and the library was added
to unit tests that use the log macros.
There is also a dependency on hrt_absolute_time() as well which requires
px4_platform.

Added __attribute__ ((unused)) for variables used only for log
output and flagged as unused if the message log level is compiled out.

The device level debug will have to be removed and the debugging
can be based on this new logging structure which can tell where
an error (or debug output) occured whch the current implmentation
cannot.
The one limitation is the new macros cannot take a char* for the
format parameter. It must be an actual string literal because it
is concatenated with other strings.

APU requires the use of ?= for MK_DIR but the use of lastword was
causing MK_DIR to be a subdir of makefiles. Changed lastword to
firstword (which is always the path to firmware.mk) which fixed
the problem.

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

Changed rc.S to rcS.
Updated README.md to explain the require directory structure and
where to run mainapp from for SITL to work correctly.

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/

before an advertiser for multi_pub/subs.
This is achieved using
- A "published" flag for each uORB device node
- A check before increasing the instance count (basically, a node is
re-used if nothing has been published on it before which means that it
has been created by a subscriber.
Since the PX4 code uses both px4_task and pthread APIs,
px4_getpid() must be save to call from either context.
On posix, this means we have to always return the pthread ID.
Reverted simulator change of pthread to px4_task
There may have been side effects if this was build for a target that
has process/task scoped file descriptors. It is now safe to call
px4_getpid() from this pthread context with this change for the
posix build for px4_getpid().

In nuttx the mode parameter to open is not required but in Linux,
and per the POSIX spec, mode is required if the O_CREAT flag is
passed.
The mode flags are different for NuttX and Linux so a new set of
PX4 defines was added:
PX4_O_MODE_777 - read, write, execute for user, group and other
PX4_O_MODE_666 - read, and write for user, group and other
PX4_O_MODE_600 - read, and write for user

mcu_unique_id() reads registers at an invalid address in non-nuttx builds.
Added ifdef to return a dummy value for non-nuttx builds.

The simulator was using pthread APIs directly so calls to px4_getpid()
would fail since the task ID was not known. Changed simulator to use
px4_task_spawn_cmd.
