multi-completion calls. Therefore reorder tests where appropriate.
- Always check for NULL-pointers (flag, index, completed) (yes, we
use them in the underlying ompi_request_* functions.
- Break early, if a NULL-request is found

development trees since last year (had to wait for some intel tests to
run yesterday, so I finally took the time to finish this work):
* Improve MPI API argument checking by also checking for NULL values
(especially helps when invalid Fortran MPI handles are passed,
because the various MPI_*f2c functions are supposed to return an
"invalid" MPI handle [meaning NULL] when this happens). So now
OMPI will generate an MPI exception rather than a segv.
* Removed a few redundant DATATYPE_NULL checks.
* Also check for some other forms of "invalid" handles (e.g., already
been freed, etc.) in some cases. We could probably be a bit more
stringent in this regard if we really wanted to.
* Change MPI_Get_processor_name to zero out the string up to
MPI_MAX_PROCESSOR_NAME characters, because the MPI spec says that
the string must be at least that long. We were already passing
that length to gethostname(), anyway.

This merge adds Checkpoint/Restart support to Open MPI. The initial
frameworks and components support a LAM/MPI-like implementation.
This commit follows the risk assessment presented to the Open MPI core
development group on Feb. 22, 2007.
This commit closes trac:158

This commit fixes several aspects regarding MPI conformance of requests.
* Eliminate the last argument of ompi_errhandler_request_invoke(); we
''always'' want to invoke the back-end exception handler with the
real error code.
* Make it clear in comments that we only invoke the ''first''
exception in a given array of requests, even if there's more than
one request with a non-MPI_SUCCESS value for MPI_ERROR.
* Defer the freeing of requests upon exception in the back-end
functions to MPI_WAIT* and MPI_TEST* until later; the requests are
kept so that we know what handler to invoke when we actually invoke
the exception. After figuring that out, ''then'' we free requests
with pending exceptions on them.
* Clean up return codes from the back-end MPI_TEST* and MPI_WAIT*
functions.
* Slightly modify ompi_errcode_get_mpi_code() to return unity if it
receives an MPI error code (vs. an OMPI error code).

Had group discussion about this on the weekly call. The decision was
that we should pass the real error code to the back-end exception
handler because it's pretty useless to pass MPI_ERR_IN_STATUS to the
back-end exception handler (because exception handlers don't have
access to the request or the status - this has potential issues for
fault tolerance kinds of scenarios). So in TESTALL, TESTSOME,
WAITALL, and WAITSOME, we examine the error code and if it's not
MPI_SUCCESS, return MPI_ERR_IN_STATUS.

* For MPI_TEST, MPI_TESTANY, MPI_WAIT, and MPI_WAITANY (i.e., the
TEST/WAIT functions that return up to exactly one completed
request), return the actual error code.
* For MPI_TESTALL, MPI_TESTSOME, MPI_WAITALL, MPI_WAITSOME, (i.e.,
the TEST/WAIT functions that can return more than one completed
request), return MPI_ERR_IN_STATUS.

The following Trac tickets were found above:
Ticket 549 --> https://svn.open-mpi.org/trac/ompi/ticket/549
* Create a new request type: NOOP (described below)
* For all MPI_*_INIT functions, OBJ_NEW an ompi_request_t and set its
type to NOOP
* Ensure that the NOOP requests are OBJ_RELEASE'd when they are done
* MPI_START looks at the request type; if NOOP, just return success. If
not, call the PML start() function
* MPI_STARTALL always pass the entire array of requests back to the PML
(see next point)
* Make the PMLs only process PML requests (i.e., ignore/skip anything
that isn't of type PML -- such as the NOOP requests)
* Add a little more param error checking in STARTALL

follow the statement from the standard that make the most sense to me. In this
particular case this statement is:
If there is no active handle in the list it returns outcount = MPI_UNDEFINED.

- 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)
