* Fix potential race condition with starting a new lock epoch if we
were releasing a lock
* Increment the shared counter if we start a shared lock session during
the unlock code
This commit was SVN r15186.
a WIN_FREE
* Fix race condition in threaded builds with pending unlocks and
finishing an epoch
* Fix memory leak due to use of OBJ_DESTRUCT instead of OBJ_RELEASE
* Fix race condition between releasing multiple shared locks and
starting a new lock
* Need to incremement the shared count if starting a new shared
lock once an exclusive lock finishes
This commit was SVN r15185.
OBJ_NEW
* Need to single when the passive unlock has left an expose epoch for
the win_free case
* Clean up some debugging output
* fix missing variable initialization

- adding linear algorithm with synchronization for gather.
This algorithm prevents congestion at root process, but introduces
synchronization (serializes non-root processes, but allows messages
to arrive from two processes at the same time).
It performed better than binomial and linear algorithms for large message,
and intermediate and large communicator sizes.
- Updating MPI_Gather decision function to reflect performance results
from MX. I will perform more measurements though - so this one can
change.

to make checks for MPI-implementations fail in the right way ,-]
- check in configure.ac
- BINARY INCOMPATIBLE change to mpif-common.h
(if implemented the *right* way)
Actually OMPI_F90_CHECK takes two arguments, not three.
- Only have corresponding C-Type, if the opt. Fortran
type is really supported,
Otherwise pass ompi_mpi_unavailable to DECLARE_MPI_SYNONYM_DDT;

interface:
- Fix the handling of MPI_BOTTOM in various places
Update of r15030
- While being at it, handle MPI_IN_PLACE in the same way.
Convert OMPI_ADDR -> OMPI_F2C_BOTTOM
Convert OMPI_IN_PLACE -> OMPI_F2C_IN_PLACE
and have them converted before the actual call.
- Approved by George and tested with icc and simple f77 mpi-program and
with program by Daniel.

reason it's that we don't have the nice configure stuff, so detecting
when to enable the CR PML it's kind of hard. Keep it defined and at
least it compile smoothly.

* Support btl_openib_if_include and btl_openib_if_exclude MCA
parameters, similar to those supported by other BTLs. Each take a
comma-delimited lists of identifiers. Identifiers can be HCA
interface names (e.g., ipath0, mthca1, etc.) or an HCA interface
name and port numbers (e.g., ipath0:1, mthca1:2, etc.). It is an
error to specify both _include and _exclude. If you specify a
non-existant (or non-ACTIVE) HCA and/or port, you'll get a warning
unless you disable the warning by setting the MCA parameter
btl_openib_warn_nonexistent_if to 0.
* Start updating to use BEGIN_C_DECLS and END_C_DECLS
* A few other minor fixes that were picked up along the way.

single threaded builds. In its default configuration, all this does
is ensure that there's at least a good chance of threads building
based on non-threaded development (since the variable names will be
checked). There is also code to make sure that a "mutex" is never
"double locked" when using the conditional macro mutex operations.
This is off by default because there are a number of places in both
ORTE and OMPI where this alarm spews mega bytes of errors on a
simple test. So we have some work to do on our path towards
thread support.
Also removed the macro versions of the non-conditional thread locks,
as the only places they were used, the author of the code intended
to use the conditional thread locks. So now you have upper-case
macros for conditional thread locks and lowercase functions for
non-conditional locks. Simple, right? :).
