Fix nasa#121, initial implementation of coverage test

Create a "ut-stubs" and "ut-coverage" subdirectory under each
of the submodules, and hook into the build system gated upon
the setting of BPLIB_ENABLE_UNIT_TESTS.

This is only the initial framework, most test cases are still not
implemented and need to be added.
