This allows oe-selftest to take a -j option which specifies how much test
parallelisation to use. Currently this is "module" based with each module
being split and run in a separate build directory. Further splitting could
be done but this seems a good compromise between test setup and parallelism.
You need python-testtools and python-subunit installed to use this but only
when the -j option is specified.
See notes posted to the openedmbedded-architecture list for more details
about the design choices here.
Some of this functionality may make more sense in the oeqa core ultimately.
