was that declaring the type of MPI_WTICK and MPI_TIME in mpif-common.h
would allow the F90 bindings to call through to the back end f77
function and have the right return type. But upon reflection, that's
silly -- we were just declaring the variables MPI_WTICK and MPI_WTIME
that were of type double precision. Duh.
So add some fixed (non-generated) wrapper F90 functions to call the
back-end *C* MPI_WTICK and MPI_TIME functions (vs. the back end *F77*
functions). We have to call the back-end C functions because there's
a name conflict if we try to call the back-end F77 functions -- for
the same reasons that we can't "implicitly" define MPI_WTIME and
MPI_WTICK in the f90 module, we can't call such an implicitly-defined
function. So we had to add new back-end C functions that are directly
callable from Fortran, the easiest implementation of which was to
provide 4 one-line functions for each (rather than muck around with
weak symbols).

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.

call to the _UNPACK macro, in the case where the length of the received data
is zero. This might happens on the PUT protocol.

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).

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.

correctly compute the final checksum. This is not a bug in the case where
both the sender and the receiver execute EXACTLY the same checksum
computations but is definitively a problem if not (such as the buffered case).

with the last one was that the resized function only set the soft lb and ub
markers without actually moving the usefull data up to the correct
displacement. Using a struct instead solve the problem. Anyway, as defined
in the MPI standard we have to set the lower bound and the upper bound
of the new type to the correct values too.

- add more comments on the pack and unpack functions.
- remove all pack/unpack versions that are not used anymore.
- other various cleanups.
- update the safeguard macro (which compute theboundaries of the
datatype in order to protect us from accessing memory locations
outside of the data).
- for the contiguous (with or without gaps) pack and unpack correctly
compute the starting point.
This commit was SVN r10327.
- Added some basic flow control to limit number of posted sends.
- Merged endpoint send/recv lock into single endpoint lock.
- Set the LMR triplet length in the send path, not at allocation time.
This has to be done because upper layers might send less than the
amount allocated.
- Alter the tie-breaker if statement protecting the second call
to dat_ep_connect(). The logic was reversed compared to the tie-
breaker for the first dat_ep_connect(), making it possible for
3 or more processes to form a deadlock loop.
- Some asserts were added for debugging purposes.. leaving them
in place for now.
