BTLs will still be used for RDMA transfers for the PML and for
send/receive communication for the OSC component)

happens before digging for a PML, while the destruction just before
finalizing the component.

receive queues are shared among all PMLs, they are declared in the base PML,
and the selected PML is in charge of initializing and releasing them.
The CM PML is slightly different compared with OB1 or DR. Internally it use
2 different types of requests: light and heavy. However, now with this patch
both types of requests are stored in the same queue, and cast appropriately
on the allocation macro. This means we might use less memory than we allocate,
but in exchange we got full support for most of the parallel debuggers.
Another thing with this patch, is that now for all PML (CM included) the basic
PML requests start with the same fields, and they are declared in the same order
in the request structure. Moreover, the fields have been moved in such a way
that only one volatile/atomic will exist per line of cache (hopefully).

handles the situation where not all nodes register information for a given
node (rather than just spinning until that node sends information, like
we do today).

The problem is that in the case of threaded builds for every fifo
a head and tail lock will be allocated inside the shared memory
segment and the ptr is stored inside the fifo. In the case that the sm backend
file will be mapped in all processes at the same address (mostly the
case for non-thread builds) this is fine, but in the cases when the
processes map the file at different addresses this addresses cause big
trouble in other processes than the one that allocted the locks.
Therefore the send lock addresses have to be recalculated to match
the local mapping of the processes that use them.
