and remove the px4_ prefix, except for px4_config.h.
command to update includes:

Transitional headers for submodules are added (px4_{defines,log,time}.h)
Script to update include paths:
for i in $(grep -rl 'include <px4_work_queue' src platforms); do sed -i 's/#include <px4_work_queue/#include <px4_platform_common\/px4_work_queue/' $i; done
The simulated timer interrupt always adds a new scheduled work task, which
is called from the work queue thread. Sending the signal creates measurable
overhead (~5% of the px4 CPU runtime) and is unnecessary, since the thread
is not sleeping anyway.
The POSIX and QURT platforms contain several duplicate files.
These files have been factored out into platforms/posix/work_queue.
The config files have been updated to include the
platforms/posix/work_queue module.

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.

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 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.

Changed "linux" target to "posix". Most of the changes are shared with
QuRT and with OSX. The Linux specific parts are in for i2c which uses
<linux/i2c.h> and <linux/i2c-dev.h>.
There is also a check for __PX4_LINUX in mavlink for a tty ioctl that is
not supported.

PX4 uses NuttX data structures throughout so those data structures
were preserved and used to implement high and low priority queues.
A unit test for the work queues was added.
The polling rate of the queues are set in px4_config.h in
CONFIG_SCHED_WORKPERIOD. The units are milliseconds.

Added more queue support to linux/px4_layer.
Use virt char devices for ms5611, and mavlink.
Added more HRT functionality. uORB latency test
now fails. Likely due to bad HRT impl for Linux.
