Not much got tested that wasn't already - I've uncovered a connection establishment deadlock and wanted to get these changes committed before I attack it. The big changes: - Moved much of the connection code from btl_udapl_component.c to btl_udapl_endpoint.c. - Cleaned up initialization of various fragment members. - MCA_BTL_UDAPL_ERROR macro, which is compiled in/out appropriately. This commit was SVN r9496.
