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)

b1d2424013 Merge in present work on the MPI-2 onesided chapter. The current code is not
complete, but stable enough that it will have no impact on general development,
so into the trunk it goes.  Changes in this commit include:

 - Remove the --with option for disabling MPI-2 onesided support.  It
   complicated code, and has no real reason for existing
 - add a framework osc (OneSided Communication) for encapsulating
   all the MPI-2 onesided functionality
 - Modify the MPI interface functions for the MPI-2 onesided chapter
   to properly call the underlying framework and do the required
   error checking
 - Created an osc component pt2pt, which is layered over the BML/BTL
   for communication (although it also uses the PML for long message
   transfers).  Currently, all support functions, all communication
   functions (Put, Get, Accumulate), and the Fence synchronization
   function are implemented.  The PWSC active synchronization
   functions and Lock/Unlock passive synchronization functions are
   still not implemented

e8ae5d0047 Performance improvements. Remove all useless functions call (like when we already
know that the request is inactive we don't have to call fini). Remove if's from
the critical path. Change a do in while to make sure we do the minimum in all cases.
All in all it decrease the latency for mvapi by something between 0.15 and 0.20
micro-seconds. But it's just a first step ...

398457fc2a One possible deadlock less. This one was in req_wait_all with a threaded build. If another
thread finish a request between the moment when we check the request status and the moment
when we acquire the lock, and if there are no more pending request on the pipe we will be
stuck foreverr as nobody have any reason to broadcast the request condition. I check the
req_any and it doesn't contain the same bug.

inside (like MPI_Wait* functions).

d1a5bacc5f - Only whitespace, no functional changes, except:
- Test for MPI_REQUEST_NULL within the often executed loop not
    necessary, but left as a comment
  - The req_fini may potentially return an error, do check for it in
    req_wait.

20eebeaa14 MPI_TESTANY is described in MPI-1 p46. The last 2 full paragraphs of
the page address three situations:

1. if the array of requests are all REQUEST_NULL, set flag=true and
   index=MPI_UNDEFINED
2. if the array of requests are not all REQUEST_NULL, if any of them
   finished, set flag=true and index=whatever_the_index_was
3. if the array of requests are not all REQUEST_NULL, if none of them
   finished, set flag=false and index=MPI_UNDEFINED

With regards to the index value, we are currently doing 1 and 2, but
not 3.  More specifically, index should be set to MPI_UNDEFINED if no
requests are found to have completed (regardless of whether they are
REQUEST_NULL or not).

This patch fixes this problem.

note that any code that sets a request to a completed state must
now increment a counter for every completed request

1302cb4072 The next in a long line of crazed build system changes from Brian. This was
originally suggested by Ralf Wildenhues, to try to speed autogen, configure,
and make (and possibly even make install).  Use automake's include directive
to drastically reduce the number of Makefile files (although the number of
Makefile.am files is the same - most are just included in a top-level
Makefile.am).  Also use an Automake SUBDIRs feature to eliminate the
dynamic-mca tree, which was no longer really needed.  This makes adding
a framework easier (since you don't have to remember the dynamic-mca
tree) and makes building faster (as make doesn't have to recurse through
the dynamic-mca tree)

ed56e743b7 * update configure.ac to use the modern version of AC_INIT and
AM_INIT_AUTOMAKE, instead of the deprecated version.
* Work around dumbness in modern AC_INIT that requires the version
  number to be set at autoconf time (instead of at configure time, as
  it was before).  Set the version number, minus the subversion r number,
  at autoconf time.  Override the internal variables to include the r
  number (if needed) at configure time.  Basically, the right thing
  should always happen.  The only place it might not is the version
  reported as part of configure --help will not have an r number.
* Since AM_INIT_AUTOMAKE taks a list of options, no need to specify
  them in all the Makefile.am files.
* Addes support for subdir-objects, meaning that object files are put
  in the directory containing source files, even if the Makefile.am is
  in another directory.  This should start making it feasible to
  reduce the number of Makefile.am files we have in the tree, which
  will greatly reduce the time to run autogen and configure.

15c4ae3391 Fix for buglet #1423.
Any non-blocking P2P function should set the request to something else
then MPI_REQUEST_NULL, when passed a source/dest of MPI_PROC_NULL.

Introduce a new ompi_request_empty, which returns the
MPI_SOURCE=MPI_PROC_NULL, MPI_TAG=MPI_ANY_TAG, count=0 as specified by
the MPI-standard.
