Patch from Scott McKellar:

This patch elinminates the use of the osrf_clearbuf macro in several
spots.  In each case, the buffer needs to be initialized to an empty
string, because the call to jid_get_* doesn't necessarily populate it
with anything else.  In debugging mode, osrf_clearbuf() will fill the
field with exclamation points, which is not helpful in this context.
