Major reorganization:

Removed all Main.cpp files, use the macro in testMain.h instead and
defaulted all argc/argv parameters.
Converted all real test programs to use epicsUnitTest.h.
Moved performance measurements from epicsThreadTest to epicsThreadPerform.
Moved epicsOkToBlockTest tests into epicsThreadTest.
On a host arch,  make test  inside the O.arch directory runs all tests.
