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.

Compile Time - Conditional inclusion of the Node Allocation and FW Server

Makefile cleanup

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.

Added description of how to create required directories

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

add simulated gps driver to startup for SITL

SITL: changed posix_default to posix_sitl

This is a temporary hot fix for lost data

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.

test which fails because it does the subscription before the advertisement.

POSIX: px4_getpid() fix

Shifted the set() function for Matrix3x3, Vector2, Vector3, Vector4 to a...

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().
