Remove coverity settings since that's in its own branch
Remove old CMake PPA (Trusty has a more recent version)
Remove ccache from APT install since we build it from source
Disable caching ccache DB between builds
Don't run jobs on cron that won't do Make builds
This makes param parse failures much more obvious in the CI logs, as
well as ensuring that both Semaphore and Travis will fail on bad
parameter data (which should reduce user confusion when one service
passes and the other fails).
the param_parse Python script has bugs when trying to parse all vehicles at once, so make each one at a time
use the new option so that only validation is performed
Travis has fixed the bug affecting cache's names so we don't need custom compiler names anymore
Change and reorder jobs
Also add fast finish, so that when a job fails, the build fails immediately
Update ccache to 3.2.5
Set ccache size
Display ccache statistics for each build
Disable ccache for configure phase
Export ccache bin path
travis: remove ccache stats before saving cache
PX4 isn't supported at the moment and sitltest always use GCC, so we include the only ones that build
Travis has old LLVM installed and old Clang in a strange path (not a package) which interfere with the use of clang-3.7
Now that we are build every linux board twice (one with make and one
with waf) and additionally building all examples and tests, it's taking
a long time to leave all linux boards in the same thread. Let's move
some of them to the other thread.
This currently removes around 25s from compilation time while also being
more resilient to network outages. The drawback is that when changing
the compiler we may need to clean the caches.
In order to use the container infrastructure we can't use sudo to
install packages. Now Travis has a way to install packages by specifying
them in the .travis.yml. This greatly simplifies how we install the
packages and there's no need for a separate script anymore.
This also removes several outdated packages that aren't needed anymore.
