Pauli 3791646202 Add output routines to allow consistent formatting of memory, strings 
and bignums.  These have been refactored into their own file, along with
their error displays.  The formatting follows the output format used
on error, except that bignums of sixty four bits or less are displayed
in a more compact one line form.

Added a TEST_note function for producing output without file and line
information.

Update the three tests that call BN_print so they use the new test
infrastructure instead.
