2e66590993 Fix mistakes in the basic component.. can't call collectives on the communicator and always pass the basic module.. have to give them the module off the communicator.

af4e86c25f Update collectives selection logic to allow for multiple components to be
used at nce (up to one unique collective module per collective function).

74d3946342 Remove the call to set_args. This is only required for the MPI level,
because there we have to be able to return to the user the description
of the data.

427c20af0d Use a new algorithm for allgatherv. The old algorithm essentially did
N gatherv's:

  for (i = 0 ... size)
    MPI_Gatherv(..., root = i, ...)

The new algorithm simply does (effectively):

  MPI_Gatherv(..., root = 0, ...)
  MPI_Bcast(..., root = 0, ...)

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)

2c1186cd19 Fix up the offsets for the non-root gatherv in the IN_PLACE case.

0fcd682c4c MPI-2 7.3.3 description of MPI_Allgatherv is wrong -- can't just have
all processes call MPI_Gatherv(MPI_IN_PLACE...) because IN_PLACE is
only allowed to be used at the root.  Non-root processes must use
their receive buf as the send buf.

5dca18f903 First cut of handling MPI_IN_PLACE:
- added relevant logic for everything except
  mca_coll_basic_reduce_log_intra() -- need some help from George /
  Edgar on this one...
- replaced ompi_ddt_sndrcv() with ompi_ddt_copy_content_same_ddt()
  where relevant
- removed some "if (size > 1)" conditionals, because the self coll
  module will always be chosen for collectives where size==1

Waiting for BA's tests to check the validity of this IN_PLACE stuff.
We'll see how it goes!

51de13bb97 Arrgh -- re-indenting this morning accidentally used real tabs instead
of spaces (curses!  indent(1) had been updated with a new option that
I did not use).  This commit simply converts tabs to real spaces.

988f70edd8 Correct gatherv and allgatherv collective communications. Always do any internal send even if the count
is zero as the receive is always posted.

a8fa19c5c1 Patch simply to re-indent all of the basic coll component to 4 space
tabs (Jeff takes the blame for originally writing it with 2 space
tabs).  Changes to fix the PMB coming soon.
