successfully with maxixum number of priorities as 16 instead of 256.
This was done by temporarily modifying the score priority.h maximum.
This allowed testing of all API code to ensure that it worked
properly with a reduced number of priorities. Most modifications were
to switch from hard-coded maximum to using the API provided methods
to determine maximum number of priority levels.
* 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.
