openmpi/ompi/mca/btl/mx/btl_mx_endpoint.h
Rainer Keller 9dea63d63a - Last of intrusive commits (promised)... err for now.
Anyway, this is blocking the move: do not include pml.h
   if not really needed, aka none of the following used:
     mca_pml
     MCA_PML_CALL
     OMPI_ANY_TAG
     OMPI_ANY_SOURCE
     OMPI_PROC_NULL

 - Notable exceptions (deleting in one header->adding):
   - ompi/mca/mtl/psm/
   - ompi/mca/osc/rdma/
   - ompi/mca/btl/openib/btl_openib_endpoint.c depended on
     pml_base_sendreq.h

 - Tested on Linux/x86-64, this time including make check
   (thanks Jeff and Ralph)
