we send our local addr_t OOB. Remote side then matches endpoints and calls dat_ep_connect(). Everything should be the same as before from here, except that client/server roles are reversed. - Properly set our buffer size when posting receives. When the frag used to transfer address information is recycled by the free list, the wrong buffer size was being used, which caused buffer overflow errors. - Finally put the uDAPL error handling stuff in the mpool component. - Remove a few more OPAL_OUTPUTs. This commit was SVN r9569.
