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().

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.

- wait for first message from jMAVSim
before sending data
- publish raw rc data coming from PIXHAWK (temporary)
- send some interesting messages to jMAVSim
- prepare sensor data for sim drivers to read
The use of a non-static function without a declaration generates a
warning for gcc 4.8.
Clang-3.4 does not work when compiling for gprof. The executable always
generates a segv.

The existing orb_advert_t use thoughout the code sometimes tries
to treat it as a file descriptor and there are checks for < 0
and ::close calls on orb_advert_t types which is an invalid use
of an object pointer, which is what orb_advert_t really is.
Initially I had changed the -1 initializations to 0 but it was
suggested that this should be nullptr. That was a good recommendation
but the definition of orb_advert_t had to change to void * because
you cannot initialize a uintptr_t as nullptr.

The calls to orb_advertise were being mishandled throughout the code.
There were ::close() calls on memory pointers, there were checks
against < 0 when it is a pointer to a object and values larger than
0x7ffffffff are valid. Some places orb_advert_t variables were
being initialized as 0 other places as -1.
The orb_advert_t type was changed to uintptr_t so the pointer value
would not be wrapped as a negative number. This was causing a failure
on ARM.
Tests for < 0 were changed to == 0 since a null pointer is the valid
representation for error, or uninitialized.

The warnx and warn calls map to PX4_WARN.
Calls to errx or err genrtate a compile error.
The px4_log.h file implements a new log format:
For DEBUG and INFO:
<level> <msg>
For ERROR and WARN:
<level> <msg> (file filepath line linenum)
The verbosity can be changed by setting the macro to use
either linux_log or linux_log_verbose in px4_log.h

QuRT does not support UDP so moved the mavlink specific code
to a new file that is not built for the qurt target
