In the upstream tree ringbuffer.h includes the method implementations
in the header file which causes multiple definitions in the link for
other targets. Changed so ringbuffer.cpp is build separately for other
platforms and is included by ringbuffer.h on NuttX.
uORB changes do not link without uORBTest_UnitTest.cpp enabled for
the NuttX build.
px4_getopt was not exported and wasn't visible in NuttX build.
The makefiles were restored to be as close as possible to upstream
so the NuttX build builtin's work again. The code will have to be
refactored after the merge.

px4_read, px4_write, and px4_opctl were not returning the correct
value on error. They were returning -errno vs -1.

QuRT does not have a filesystem, so creating a virtual filesystem
that could be implemented as an in-memory file or a remote file
over fastRPC.

The debug message made it difficult to use the shell for the

sim.cpp was causing the posix shell to have continuous debug output.
Used debug macros to suppress output

The following should not have been defined:
PX4_DIOC_GETPRIV
PX4_DEVIOCSPUBBLOCK
PX4_DEVIOCGPUBBLOCK
PX4_DEVIOCGDEVICEID
The actual defines are in drv_device.h and are:
DEVIOCSPUBBLOCK
DEVIOCGPUBBLOCK
DEVIOCGDEVICEID
DIOC_GETPRIV is defined by Nuttx, so mapped to SIOCDEVPRIVATE for POSIX

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.

If simulate is not true, then a read I2C device is present.
The global scope ioctl should be called on _fd, not px4_ioctl.

The list_tasks and list_devices commands will show
lists of running px4 threads and created virtual device nodes.
The list_builtins command was removes and the list of commands
will be shown if return is pressed.

The MS5611_SIM class is supposed to simulate data from a real
ms5611. An externl simulator could provide an interface to
call to get data that would be returned from a transfer() call.

The simulator satisfies the dependencies for an accelerometer
being present.
The accel code compiles but is not fully functional.
Signed-off-by: Mark Charlebois <charlebm@gmail.com>
The simulated device satisfies the factory pattern used by
MS5611 to create a specific I2C or SPI device instance.
For now the functions just return true, but should/could
return simulated data.

If PX4_I2C_SIMULATE is set to 1, then the actual I2C device will
not be opened and all transfers will succeed.
If PX4_I2C_SIMULATE is false and transfer() is called, then the
appropriate ioctl is make on the actual device.
if I2C::ioctl is called via px4_ioctl() then the command fails and
a warning is printed to use I2C::transfer

I2C class derives from CDev class which requires a devname
but in at least some instances, a nullptr is passed for devname.

For now it uses the bus number as the id. Not sure how this should
actually be mapped.
Seems like the I2C devices come up in random order and have random
id but that a specific device can be found in the /sys/bus/i2c
interface.

Added more HRT functionality. uORB latency test
