* make tests use px4 instead of mainapp

* commander_tests ALTCTL - not rotary requires altitude

sitl CI is having some issue cloning, but I have verified it locally for various configs

The reason for this change is that RPi2 and RPi3 are compatible, and
hopefully all differences coming up can be resolved without ifdefs but
at runtime.

We currently only support Navio2, so let's fuse the two configurations.

For replay with the new logger, we want a separate build dir so that the
parameters file and orb rules don't get mixed up.

* move gcc 4.9 build to circleci

* travis-ci update to xcode 7.3

* travis-ci limit git fetching for OSX

* Makefile split firmware targets for CI

* OSX ccache

* Add parrot bebop build structure

* Add upload functionality to bebop build

* Add modules and commands to bebop build

* Insupport merging Spread the checks multiline lists

* Removed long line of checks

* Removed release configs for eagle

These configs are only built for internal testing

-can't sync after deinit

Adding new CMake config files which will be used to generate a build which uses the legacy sensor drivers.  This is only temporary until integration with the corresponding PX4 DriverFramework drivers is complete.
