Rename compreensive test suite to test-dev

The regression test suite is important for development but for end user
tests a simpler check is sufficient.

Add simple library test

To check whether the library was built properly we'll load and play a
test module. This should make sure that a depacker, a loader, the player,
the mixer and a portion of the API are working correctly. To check for
regressions a set of comprehensive tests (the old test suite) is executed
by the developer before publishing the tarball.

This also addresses issues related to shipping binary data with unclear
licensing terms in the distribution package.

[test] Update development test coverage target

The new makefile in test-dev has hardcoded compiler data, perhaps we
should add a new configure script in this directory too.
