Test suites for Dialyzer

This is a transcription of most of the cvs.srv.it.uu.se:/hipe repository
dialyzer_tests into test suites that use the test server framework.

See README for information on how to use the included scripts for
modifications and updates.

When testing Dialyzer it's important that several OTP modules
are included in the plt. The suites takes care of that too.
