e926bed69f Implement MPI_TYPE_CREATE_DARRAY function. Works with MPICH2 darray-pack
test, Sun's darray test, and an internal LANL test code.  I would not
assume it will work properly on other codes, as I'm still not sure I
completely understand what the standard says this function is supposed to
do.

9780a000ba Cleanup of generic reduce function and possible (low probability) bug fix.
- fixing line lengths and some of the comments
- possible bug fix (but I do not think we exposed it in any tests so far)
  temporary buffers were allocated as multiples of extent instead of 
  true_extent + (count -1) * extent.
Everything is still passing Intel tests over tcp and btl mx up to 64 nodes.

c000ee5328 Fixes trac:921
* Do not empty the list of in-flight frags during _close(); the OOB
   callback will still occur (_send_cb()) and try to remove the frag
   from the list, which will then result in an assert failure (debug
   builds).  
 * Add one more fix for a possible problem -- add an extra RETAIN /
   RELEASE pair on the endpoint to ensure that it is not actually
   freed before all in-flight frags have drained.

333357f4cc This fixes the initialization of the usable size of the shared memory.
The original code was not compensating for the space used by the header.  

When memory got tight, the allocator would return a pointer to memory that 
did not exist resulting in a SEGV for the application.  This is a partial 
fix for ticket #929.

4b63631535 Allow correct duplication for MPI_UB and MPI_LB. The problem is that we cannot
create a duplicate type, because any duplicate type lose the PREDEFINED flag.
An MPI_LB (respectively MPI_UB) without the PREDEFINED tag is useless, as it's
not the a marker anymore. The solution is to return the same pointer, but once
the reference count has been increased. In order for this to work, I allowed
the destruction to check for the reference count of an object before complaining
about destroying a predefined type.

This fixed ticket #317.

21f014f5f6 Apply a patch from Bert Wesarg.
This saves some memory for the constructors and destructors arrays of a
class by counting the constructors and destructors while we are counting
the cls_depth. And the reversion of the constructor array can now be done
without an extra loop.

8078ae5977 Optimize sm communication. Pass message type (MCA_BTL_SM_FRAG_ACK/
MCA_BTL_SM_FRAG_SEND) and status success/fail in low bits of pointers we
are passing through circular buffer. The rank that receives ACK doesn't need
to look into data it received and this is a big win since this data is not in
the cache of the rank's CPU. (Note that we can use low bits of pointers because
free_list always return pointers aligned at least to cache line size).

90fb58de4f When frags are allocated from mpool by free_list the frag structure is also
allocated from mpool memory (which is registered memory for RDMA transports)
This is not a problem for a small jobs, but for a big number of ranks an
amount of waisted memory is big.

0404444dbe * Added 2 new MCA parameters
- mca_base_param_file_prefix
     (Default: NULL)
     This is the fullname of the "-am" mpirun option. Used to specify a ':'
     separated list of AMCA parameter set files.
  - mca_base_param_file_path
     (Default: $SYSCONFDIR/amca-param-sets/:$CWD)
     The path to search for AMCA files with relative paths. A warning will be
     printed if the AMCA file cannot be found.

* Added a new function "mca_base_param_recache_files" the re-reads the file
configurations. This is used internally to help bootstrap the MCA system.

* Added a new orterun/mpirun command line option '-am' that aliases for the
mca_base_param_file_prefix MCA parameter

* Exposed the opal_path_access function as it is generally useful in other
places in the code.

* New function "opal_cmd_line_make_opt_mca" which will allow you to append a
new command line option with MCA parameter identifiers to set at the same
time. Previously this could only be done at command line declaration time.

* Added a new directory under the $pkgdatadir named "amca-param-sets" where all
the 'shipped with' Open MPI AMCA parameter sets are placed. This is the first
place to search for AMCA sets with relative paths.

* An example.conf AMCA parameter set file is located in
contrib/amca-param-sets/.

* Jeff Squyres contributed an OpenIB AMCA set for benchmarking.

Note: You will need to autogen with this commit as it adds a configure param.

2b6cbd6299 Separate frag lists for RDMA descriptors to two, one for src descriptors
and another for dst descriptors. This provide partial solution to OB1 protocol
deadlock problem. We can limit number of RDMA descriptors (by setting
btl_openib_free_list_max to something different from -1) and if we will be
lucky to hit this limit before we fail to register more memory the protocol
will not deadlock. When we had only one list for src/dst descriptors we
deadlocked when we reached max limit for the list.
