[Simpletest-support] "Deprecated" functions

[Edward Z. Y. <edw...@th...>]

Since one of the items on the TODO list is "remove deprecated
functions", I did a quick grep and found that the following functions
were marked deprecated:

SimpleTestCase->pass()
SimpleTest::setMockBaseClass()
SimpleTest::getMockBaseClass()

I commented them out and got fatal errors on the test suite. It seems to
me that the functionality these methods provide is necessary, and we'll
need suitable alternatives if we want to get rid of them.
SimpleTestCase->pass() being deprecated is especially surprising, since
this is the only we can render passes in our test suite, which can be
useful when implementing a --verbose mode to check for hanging, etc.

Cheers,
Edward
