Currently, there is a mismatch of allowed string sizes in UnitTestLib. The UT_LOG_* macros allow a string size of 512, but failure messages are constrained to 120 characters and some other string lengths are similarly constrained. 120 characters is too few for some longer error messages, particularly the ones that print out the path to the failing line. This can result in the actual error not getting printed in the log. This patch updates all UnitTestLib allowed string lengths to be 512 characters.

generally called from within a test case prior to quitting or rebooting.
