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.
