This commit changes the underlying opal complex datatypes to match the
C99 types: float _Complex, double _Complex, and long double _Complex. The
fortran and C++ types now are aliases to these basic types instead of
structure types. The operators in ompi/mca/op/base now work on only the
C99 types and the fortran types use these operators if the fortran type
matches a C complex type (this should almost always be the case.)
C99 is not is use in both the datatype and operator code and should make
the code both cleaner and much less fragile.

- add support for MPI_IN_PLACE in the self collective component.
- fix the extent usage in the tuned collective component.
- correctly use the peer counts instead of local - add support for MPI_IN_PLACE in the self collective component.

Thanks to Fujitsu for the patch.

MSGDEBUG2 now means "print a one-liner for all PML calls into BTL, and
also when BTL calls PML with a recv completion (not send completions)"
MSGDEBUG1 means print more internal gory detail
MSGDEBUG is gone, replaced by MSGDEBUG1
In the process also found that PUT_DEST style fragments could
potentially be leaked in usnic_free() since send_fragment tests were
being applied to see if it was eligible to be freed.

changes required to support MPI_Bsend(). Introduces concept of
attaching a buffer to a large segment that the PML can scribble into and
we will send from. The reason we don't use a pinned buffer and send
directly from that is that usnic_verbs does not (yes) support num_sge>1
for regular sends. This means the data gets copied twice, but that is
unavoidable.
changed the logic in handle_large_send to be more sensible

Do not assume that the "size" passed to alloc_send() will be the same as
the size of the message the resulting fragment will hold when
usnic_send() is called. This means usnic_send()/usnic_put() can never
trust any pre-computed size values, and are only allowed to look at the
lengths and pointers of the elements in the desc SG list.

- tag needs to be sent in *our* header, not the PML header
- usnic_alloc() should return smaller value if too much data requested
- be careful about callbacks vs removing items from lists
(we need to remove from outr lists *before* the callback)
- improve send callback handling
- add some more MSGDEBUG2 logging and cleanup

child stdout and falls back to plain pipe if openpty fails. Child uses
the 'usepty' flag to decide whether to treat this descriptor as a pty
or as a pipe.
Set 'usepty' flag to 0 upon openpty failure to inform the child that
it isn't dealing with a pty even though pty has been requested.

The intercomm "merge" function can create a linkage between procs that was not reflected anywhere in a modex, and so at least some of the procs in the resulting communicator don't know how to talk to some of the new communicator's peers.
For example, consider the case where:
1. parent job A comm_spawns a process (job B) - these processes exchange modex and can communicate
2. parent job A now comm_spawns another process (job C) - again, these can communicate, but the proc in C knows nothing of B
3. do an intercomm merge across the communicators created by the two comm_spawns. This puts B and C into the same communicator, but they know nothing about how to talk to each other as they were not involved in any exchange of contact info. Hence, collectives on that communicator now fail.
This fix adds an API to the ompi/dpm framework that (a) exchanges the modex info across the procs in the merge to ensure all procs know how to communicate, and (b) calls add_procs to give the btl's a chance to select transports to any new procs.

renamed all "f77" and "f90" directory/file names to "fortran"
(including removing shmemf77 / shmemf90 wrapper compilers and
replacing them with "shmemfort").
2. Fixed several Fortran coding errors.
3. Removed lots of old/stale comments that were clearly the result of
copying from the OMPI layer and then not cleaning up afterwards (i.e.,
the comments were wholly inaccurate in the oshmem layer).
4. Removed both redundant and harmful code from oshmem_config.h.in.
5. Temporarily slave building the oshmem Fortran bindings to
--enable-mpi-fortran. This doesn't seem like a good long-term
solution, but at least you can now build all Fortran bindings (MPI +
oshmem) or not. *** SEE MY NOTE IN config/oshmem_configure_options.m4

The FREE_LIST_*_MT stuff was introduced on the SVN trunk in r28722
(2013-07-04), but so far, has not been merged into the v1.7 branch yet
(2013-09-06). So put it in its own #ifdef, rather than defining it
based on OMPI_MAJOR_VERSION/OMPI_MINOR_VERSION.

The Cisco-maintained v1.6 port of the usnic BTL has diverged from the
upstream trunk and v1.7 branches. This commit adjusts the trunk to more
closely match the v1.6 branch to simplify future merging and
cherry-picking.
The usnic MCA parameters also need work on this side.

The fix for the HPL SEGV was incorrect because it assumed the
prepare_src() routine was always allowed to return "bytes processed"
less than the requested "bytes to send". It turns out this is only true
if the convertor is what limits the size, we are not allowed to limit
the data sent for our own reasons, else we break login in the upper
layers.
This means we need to learn the number of bytes out of the size
requested the convertor will give us, no matter how big the size is.
Unfortunately, this is a destructive test, and (currently) the only way to
learn that number is to actually have the convertor copy the data out into
buffers.
This change implements this, copying the entire data out into a chain of
send segments which are attached to the large send fragment. Now we can
always return the proper size value to the PML.
