1. fix a bug in pml_ob1_recvreq/sendreq.c, buffer was made defined where the request has already been released. 2. complete memchecker support for collective functions. 3. change the wrongly spelled function name of memchecker, i.e. '*_isaddressible' should be '*_isaddressable' This commit was SVN r20043.
