Portals
* Fix overuse of proc_pml pointer on the ompi_proc structuer,
splitting into proc_pml for pml data and proc_bml for
the BML endpoint data
* bug fixes in bsend init code, which wasn't being used by
the OB1 or DR PMLs...

Also changed some names like size to comsize so we know which sizes we are using where

order the BTL depending on the real latency for the eager protocol. Starting from now, the
latency one can specify for the devices will be in micro-second, while the bandwidth is in Mbs

mpi_leave_pinned when multiple OpenIB HCA ports are found.
Specifically, if mpi_leave_pinned == 1 and ultiple HCA ports are
found, the MCA parameter btl_openib_max_btls is set to 1. If the MCA
parameter btl_openib_warn_leave_pinned_multi_port is true, emit a
warning that this happened (having an MCA parameter to control the
warning allows users/sysadmins to turn it off instead of being nagged
for every run).

io_romio_enable_parallel_optimizations set to something non-zero.
This will enable some magic flags in Panasas if the user didn't
set them (either on or off) and do some slightly better things
with strided collective writes.

able to know how the message is fragmented between the network devices or inside
the communication protocol.

the GET function. At the end make sure that at least on communication protocol is
specified, otherwise force the send flag.

is just one network between the 2 peers. Unfortunately, this problem is present

time.
UD is connectionless, and as long as peers are statically assigned to QPs,
there is no reason to set up the adressing information lazily.
Lots of code was axed, as endpoints no longer have state. Removed a
number of other elements in the endpoint struct to make it as lightweight
as possible.
I was able to remove an entire function call/branch in the send path,
which I believe is the main contributor to a 2us drop in NetPIPE latency.
Some whitespace cleanups as well.
Passes IBM test suite, and all but certain intel tests that were failing
before the change, over ob1 PML.

1. ompi/mca/btl/udapl/btl_udapl_proc.c should be including
btl_udapl_endpoint.h for mca_btl_udapl_proc_insert function.
2. btl_udapl_endpoint.c it looks like you are using
&endpoint->endpoint_lock when you should use &ep->endpoint_lock in a
OPAL_THREAD_LOCK call.
3. btl_udapl_frag.h has a couple opal_list_item_t's that should be
ompi_free_list_item_t in the _FRAG_ALLOC_{EAGER,MAX} macros.

send/receive queues if there is something available in the short message
rdma queues, then we have to poll *ALL* the rdma queues before exiting,
or we aren't fair about frag reception and fall into degenerate matching
cases.

where to look for registrations that were used in the alloc/free code don't
work (because the memory returned from malloc() -- whowever gets around to
calling it) might actually be registered already. So just call malloc
and free directly and avoid the whole issue when leave pinned is on. After
all, you have to pay the registration cost sometime, and if leave pinned
is on, you only have to pay it once. It makes things much simpler to
have that once be at first use rather than during ALLOC_MEM, and as far
as I can read, we're still standards conformant this way.
