This saves time when building on Travis CI: unconditionally fetching all
submodules takes about 40 seconds, but not all are needed for any given
port, so only fetch as necessary.
This change brings the following benefits:
- all existing tests and test behaviour is be retained
- can now use Travis parallel build mechanism
- total time for tests is about 5 mins 30 secs, down from around 10 mins
- two additional test suites are now run: standard (non coverage) unix
build and nanbox unix build
- much easier to see what is failing: if you click through to the Travis CI
details each parallel build job is displayed with pass/fail
- scales much better when adding new test targets
Coveralls requires a "recent" version of urllib3, whereas requests requires
a "not so recent" version, less than 1.23. So force urllib3 v1.22 to get
it all working.
Previously, testing of stackless build happened (manually) in
travis-stackless branch. However, stackless offers important
featureset, so it's worth to test it as a part of the main
CI. Strict stackless is used because it's the "real" stackless
build, which avoids using C stack as much as possible (non-strict
just prefers heap over C stack, but may end up using the latter).
This allows to test the PYBV11 target as well as the network drivers
without adding another rule. It also removes the need to use -B,
side-stepping the issue of whether or not -B works with qstr auto
generation.
The STM32 F7 and L4 boards use significantly different code to the F4
boards so it's important to test them with CI. To keep CI build times
within a reasonable limit the STM32F4DISC board is no longer built, it's
anyway very similar to the standard F4 build for PYBv1.0.
This is actually long overdue: the README in the windows directory has been
updated once to indicate mingw32 is abandoned and not ok to use with uPy,
but we forgot travis builds were still using it.
As a bonus the travis build will succeed again since moduerrno.c now compiles.

There appears to be issue signature problem with the PPA package we use,
so workaround it this way for now. Warning: with broken signature, there's
always a possibility that PPA was hacked and ships trojaned binaries.
