NOTE: the code provided by PANASAS includes a "switch" that they left incomplete - it doesn't cover all possibilities. Since the value being switched is an enum, this causes problems for the compiler. I added the missing values, but - since Panasas felt they could be ignored - had the switch generate an error if those cases ever occurred.

* Include all the stuff that is necessary for running autogen.sh in a
distribution tarball.
* Remove from config/Makefile.am's EXTRA_DIST that which is
automatically included in the tarball in recent versions of
Automake (i.e., all the m4 files that are acincluded).
* Make ROMIO's configure script look for something that is actually
included in the tarball.
Fixes trac:1025.

idea at the time, but led to logistical difficulties in importing new
versions of ROMIO:
* We are effectively eliminating the ROMIO file prefix rule hacks in
the ROMIO component, which create symlinks from foo.c to
io_romio_foo.c. In reality, the file name conflict potential will
be small.
* Additionally, we are effectively eliminating the ROMIO function
prefix rule in the ROMIO component. This is another place where
there are generally problems with the merge up new versions of ROMIO
and/or patches from the user community (for their own local builds).
In reality, since other major MPI implementations provides the same
exact symbols, it won't cause any practical problems for users.
In return, we make it ''much'' simpler to apply ROMIO patches to Open
MPI. The problem right now is that any patch will have filenames such
as ad_panfs.c, but Open MPI will only have io_romio_ad_panfs.c, making
things extremely difficult for users. I believe, for example, that
this would make it possible for LANL to have applied their patches
without too much hassle on either their part or our part. It will
also make things easier for OMPI when we/they want to do the next
ROMIO upgrade (this was one of the sources of problems on each
upgrade).

single threaded builds. In its default configuration, all this does
is ensure that there's at least a good chance of threads building
based on non-threaded development (since the variable names will be
checked). There is also code to make sure that a "mutex" is never
"double locked" when using the conditional macro mutex operations.
This is off by default because there are a number of places in both
ORTE and OMPI where this alarm spews mega bytes of errors on a
simple test. So we have some work to do on our path towards
thread support.
Also removed the macro versions of the non-conditional thread locks,
as the only places they were used, the author of the code intended
to use the conditional thread locks. So now you have upper-case
macros for conditional thread locks and lowercase functions for
non-conditional locks. Simple, right? :).

Per default this feature is disabled, to enable it you need to
configure with --enable-visibility and obviously you need a compiler

same "restrict" check as the top-level OMPI configure.ac script so
that it will guarantee to always get the same result. Therefore, the
#define for restrict will always have the same value in both
opal_config.h and romioconf.h, and we get 7 less warnings (6 in the IO
ROMIO component, 1 in ROMIO itself) when compiling with icc on Linux
(because PAC_C_RESTRICT and AC_C_RESTRICT would get different values
for the "restrict" #define in this case).

Per discussions with Brian and Ralph, make a slight correction in
where components are installed. Use $pkglibdir, not $libdir/openmpi,
so that when compiled in the orte trunk, components are installed to
the right directory (because the component search patch is checking
$pkglibdir).

The top-level OMPI configure script already checks for "restrict" and
will issue a #define for it. PAC_C_RESTRICT would also check for
restrict, but sometimes come up with a different answer than the
top-level OMPI configure script, thereby resulting in conflicting
#define's for "restrict" (e.g., icc 9.0/9.1 on linux x86-64).
So it's easiest just to remove this test from ROMIO's configure.in
script.

* Ensure that the NOOP requests are OBJ_RELEASE'd when they are done

not, call the PML start() function
* MPI_STARTALL always pass the entire array of requests back to the PML

* Make the PMLs only process PML requests (i.e., ignore/skip anything
that isn't of type PML -- such as the NOOP requests)

things I found:
- Locking should prevent it from happening (I think), but there was a
race condition in the component progress -- a callback could be
triggered that would free the request before it was off the outstanding
requests list.
- When pulling a request off the component free list, make sure to
reinitialize the free_called state on the IO request. This was
what was causing Edgar's failures
- In the request cleanup code, pull the request out of the per-
component free list before returning to the free list. This
probably would cause asserts to fire, although it looks like
I wrote the loops such that it would have been memory safe if
the asserts didn't fire. Not really sure why I did that, but
let's try it again...
This should go to the v1.0 and v1.1 branches.

- We had a bad conditional choice, such that asking for pvfs2 would
result in pvfs trying to build as well, which was going to fail.
- We didn't try to link in the libray for PVFS2's adio component.
- We were clobbering romio_flags, so it was impossible to pass
flags to romio (like the selection of filesystems)
