itrontask03/init.c, itrontask04/init.c, itrontime01/init.c: Change
TEST_INIT to CONFIGURE_INIT. Make tmacros.h available to all POSIX
tests. Add a clock_settime case for < 1988.
* Per PR47 add support for buffered test output. This involved
adding defines to redirect output to a buffer and dump it when
full, at "test pause", and at exit. To avoid problems when redefining
exit(), all tests were modified to call rtems_test_exit().
Some tests, notable psxtests, had to be modified to include
the standard test macro .h file (pmacros.h or tmacros.h) to
enable this support.

adjustments so test output matches screens more reliably.
