bd870519fd - modified convertor copy_and_prepare routines to accept an addition
flag, new flags to be included when convertor is initialized
- modified pml/btl module defs and added stub functions for diagnostic
  output routines to dump state of queues / endpoints
- updates to data reliability pml

566a050c23 Next step in the project split, mainly source code re-arranging
- move files out of toplevel include/ and etc/, moving it into the
    sub-projects
  - rather than including config headers with <project>/include, 
    have them as <project>
  - require all headers to be included with a project prefix, with
    the exception of the config headers ({opal,orte,ompi}_config.h
    mpi.h, and mpif.h)

068b9c72a2 Bunches of changes
- remove redundant OBJ_CONSTRUCT in bcast
- fix up some macros in coll_sm.h
- check to ensure that if there are too many processes in the
  communicator (i.e., if we couldn't fit a flag for each of them in
  the control segment), then fail selection
- setup the in_use flags properly
- adapt to new mpool API
- first working copy of reduce -- not tree-baed (but still
  NUMA-aware), and only processes in order from process 0 to process
  N-1 -- do not have a tree-based and/or commutative version yet
  (i.e., process the results in whatever order they arrive)

Reduce now passes the new ibm reduce_big.c test.  Woo hoo!  Time to
declare success for the evening (and run the intel test tomorrow).

9302f924ea simplify the bcast code by taking abstract actions and making them
macros -- will help with the other algorithms

7bab4ed269 bunches of updates
- finally added "in use" flags -- one flag protects a set of segments
- these flags now used in bcast to protect (for example) when a
  message is so long that the root loops around the segments and has
  to re-use old segments -- now it knows that it has to wait until the
  non-root processes have finished with that set of segments before it
  can start using them
- implement allreduce as a reduce followed by a bcast (per discussion
  with rich)
- removed some redundant data on various data structures
- implemented query MCA param ("coll_sm_shared_mem_used_data") that
  tells you how much shared memory will be used for a given set of MCA
  params (e.g., number of segments, etc.).  For example:

  ompi_info --mca coll_sm_info_num_procs 4 --param coll sm | \
	    grep shared_mem_used_data

  tells you that for the default MCA param values (as of r7172), for 4
  processes, sm will use 548864 bytes of shared memory for its data
  transfer section
- remove a bunch of .c files from the Makefile.am that aren't
  implemented yet (i.e., all they do is return ERR_NOT_IMPLEMENTED)

Now on to the big Altix to test that this stuff really works...

bc72a7722b Updates:
- bcast now works properly for root!=0 and multi-fragment messages
- destroy mpool when communicator is destroyed
Still need to implement:
- "in use" flags for groups of fragments so that "wrapping around" in
  the data segment doesn't overwrite not-yet-read data
- ensure that shared memory isn't removed before all processes have
  finished with it (e.g., during COMM_FREE)
