* Added Create_errhandler for MPI::File
* Make errors_throw_exceptions a first-class predefined exception
handler, and make it work for Comm, File, and Win
* Deal with error handlers and attributes for Files, Types, and Wins
like we do with Comms - can't just cast the callbacks from C++
signatures to C signatures. Callbacks will then fire with the
C object, not the C++ object. That's bad.

add_error_class and add_error_code files. Also fixed the update of the
lastusedcode attribute, all of work according to my tests pretty fine.
Please note: the testcode attached to the bug 683 still reports some bugs. I
am however pretty sure that the testcode is wrong at that points:
- the standard says that the attribute MPI_LASTUSEDCODE has to be updated for
a new error_class or a new error_code. The test currently assumes, that only
the add_error_code call changes the attribute value.
- you have to comment out the two lines 73 and 74 in order to make the
test finish, since these lines check for the error string of non-existent
codes.
- line 126 the error-string of MPI_ERR_ARG is not "invalid argument" but a
little bit more, so the test thinks the output is wrong. So probably the test
has to be update to match the according error string of MPI_ERR_ARG.

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).

- we have to be able to attach a string to an error class, not just to an
error code
- according to MPI-2 the attribute MPI_LASTUSEDCODE has to be updated
everytime you add a new code or a new class. Thus, you have to have single
list for both.
Thus, we got rid of the error_class structure. In the error-code structure, we
can distinguish whether we are dealing with an error code or an error class by
looking at the err->code element of the structure. In case its value is
MPI_UNDEFINED, the according entry is a class, else it is an error code. All
predefined error codes have the code and the class field set to the same
value.
The test MPI_Add_error_class1 passes now.

* 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.

* 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

"this is bogus" kind of answer. Passing in bad error codes should
only happen in erroneous sections of the OMPI code base, but still,
it's far more social to print a message saying, "hey, you messed up!"
rather than seg faulting.

- 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)

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

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)

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.
