Added a verbose option to the generated test suites which can list the
dependencies not met for skipped test cases.
Also clarifies internal interfaces between the main_test.function and test code,
and fixed a bug on calculating available tests in run-test-suites.pl.
Following fixes:
* In the test script, 'basic-build-test.sh', the total number of functions had
a broken RE, and was picking up the number of tested functions.
* Titles of tests was misleading
* The 'run-test-suites.pl' script was mistaking dSYM directories as test
suites to be executed.
