* Code cleanup and rationalization * Fixed: mca_pml_base_send/recv_request are now allocated before recreation by the PML-V * Fixed: pointer arithmetic bug in sender based that crashed * Changed: directory structure. This is one step forward using autogen.sh to build static-components.h (it needs to have the directory structure of a mca framework for this). This commit was SVN r15878.
