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.

Have no idea why this function always returns a failure. It should
always return SUCCESS (provided the status is value).

* 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.

This commit essentially caches the invoking comm/win/file on the
ompi_request_t. This, paired with the req_type field, allows us to
retrieve the invoking MPI object and invoke the proper errhandler.
The patch is missing most updates for the MPI-2 one-sided stuff (i.e.,
the patch mainly fixes comms and files); I didn't really understand
that code and didn't want to hazard trying to figure it out when Brian
can probably do it much more quickly.
So #250 will still stay open, pending MPI-2 one-sided updates for this
stuff.

* 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

allocation logic is completely done outside the data-type engine (in the PML) there is
no need for any special case inside the data-type engine. There is less arguments for
the ompi_convertor_pack and ompi_convertor_unpack as well (the last field free_after is
not required anymore as there is no memory allocated in the engine itself). This change
affect all components using datatypes. I test most of them, but it might happens that I
miss some ... If it's the case please let me know (don't shoot the pianist!!).

all platforms. The only exceptions (and I will not deal with them
anytime soon) are on Windows:
- the write functions which require the length to be an int when it's
a size_t on all UNIX variants.
- all iovec manipulation functions where the iov_len is again an int
when it's a size_t on most of the UNIXes.
As these only happens on Windows, so I think we're set for now :)

* Update comments in some MPI_FILE_* functions to reflect that the
MPI specs have different page numbers in the ps and pdf (woof!).
* Update comments to say "Retain" where we meant retain (not "return)
* Add a check in MPI_ERRHANDLER_FREE to raise an MPI exception if the
user attempts to free an intrinsic errhandler *and* the refcount is
1 (meaning that it would actually free the intrinsic). This
protects erroneous programs from segv'ing.
* Remove lengthy comment from comm_get_errhandler.c which is no
longer valid (because of the MPI-2 errata that says that users *do*
have to call MPI_ERRHANDLER_FREE).

an errhandler on a communicator, you must be able to FREE it, even
if it's an intrinsic).

to return the value on seconds not some other unit based on the resolution
of MPI_Wtick. Which I think it's the wrong solution, as instead of forcing
the user to do additional computations in order to convert when he needs
the result in seconds, force us to convert every time. Unfortunately,
converting requires a division with a double which is a costly
operation. But, MPI is a standard and we have to follow it ...

Only after the argument checking do we shortcut. Fixes trac:237, which
was caused by moving the MPI_PROC_NULL test in MPI_Bsend_init,
but not allowing for MPI_PROC_NULL when checking rank.

with the last one was that the resized function only set the soft lb and ub
markers without actually moving the usefull data up to the correct
displacement. Using a struct instead solve the problem. Anyway, as defined
in the MPI standard we have to set the lower bound and the upper bound
of the new type to the correct values too.
