This reverts commit 31572852.

Fix the firmware build rules so that we always know how to build all the firmwares and thus we can have dependencies between FMU and IO firmware handled a little more sensibly.

In order to save people from themselves, force a given FMU version to depend on the corresponding _default IO version. This avoids the risk of building a new FMU ROMFS with an old IO firmware, at the cost of the sanity of anyone reading this.

If there is an IO firmware image already built when we build the corresponding FMU ROMFS, copy it into the ROMFS. Note - due to there being no fixed build ordering, to be certain that you have the most current IO firmware, you must build the IO firmware explicitly first.

Fmuv2 bringup lsm303d config

Conflicts:

	Debug/openocd.gdbinit
	Debug/px4fmu-v1-board.cfg

Note: We now use the version of stm32f4x that comes with openocd 0.7.0 or later

the qualified names were not working with current versions of python

Fixed accel self test

Support for external mags with different rotation

Minimized nshterm flags, fixed some pretty stupid non-standard coding in top, now behaving with two shell instances as expected
