lower_bound is now directly added to the user pointer when the convertor
is created, instead of having to add it all over the places inside the
pack/unpack functions.

* Change the type of Fortan's MPI_STATUSES_IGNORE to double complex
so that it will never possibly be mistaken for a real status (i.e.,
integer(MPI_STATUS_SIZE)), particularly in the F90 bindings. See
comment in mpif-common.h explaining this (analogous argument to
MPI_ARGVS_NULL for MPI_COMM_SPAWN_MULTIPLE).
* Add second interfaces for the following functions that take a double
complex (i.e., MPI_STATUSES_IGNORE). This required adding the second
interface in mpi-f90-interfaces.h[.sh] and then generating new wrapper
functions to call the back-end F77 function for each of these four, so
we added 4 new files in ompi/mpi/f90/scripts/ and updated the various
Makefile.am's to match:
* MPI_TESTALL
* MPI_TESTSOME
* MPI_WAITALL
* MPI_WAITSOME
The XSL is now not in sync with the scripts. Although I suppose that
that is becoming less and less important (because it does not impact
the end user at all -- to be 100% explicit, no release should ever be
held up because the XSL is out of sync), but it will probably be
important when we go to fix the "large" interface; so it's still worth
fixing... for now...

btl_openib_ib_mtu and btl_mvapi_ib_mtu MCA params by showing the valid
values what what they represent (got a question about this from Cisco
testing engineers).

UD is the Unreliable Datagram transport for Infiniband, specifically OpenIB. This BTL is derived from the existing openib BTL, which is RC (Reliable Connection) based.
Still a work in progress, as there is a lot of work left to do. Specifically, performance, scalability, and flow control need to be addressed.
Currently I'm playing around with different methods for handling receive buffers, as well as profiling to figure out where the time is going.

the cases. Instead replace it with a better solution, which work even for
fragments received not in order. However, this solution work only on the
current supported modes in ompi (homogeneous & heterogeneous with endianess).
The method is tricky. We will rely on 2 partial unpacks. First we will find
a byte that is not on the data to unpack, and we will pad the data with this
byte. Once we have the full length as expected, we will unpack the data, and
all the bytes in the unpacked form which do not match the unused byte will be
copied into the user buffer. This way we will reconstruct the unpacked data
in 2 times, once for the begining and once for the end.

they will be contiguous even when a multiple of them are send. This is the difference
between the NO_GAPS and CONTIGUOUS flags: contiguous one suppose that the data might
have gaps in the begining and/or at the end but the content of the data is contiguous.

pack is if the data has the BASIC flag which means it is predefined and contiguous.
For the unpack the convertor has to be homogeneous plus the same requirements
as for the pack.

1) don't need tree if memory is just malloc'd
2) fix memory and free list leak..
3) deregister first and then free... doh..
This commit was SVN r10251.
Added a tree to track memory allocation from MPI_Alloc_mem, this allows us to
free the registrations in a sane fashion.. also should be faster..

user specify a count equal to zero it will get back a datatype with the size, lb, ub,
true_lb and true_ub set to zero (very similar to the MPI_DATATYPE_NULL except it can
be used for communications).
