This merges the branch containing the revamped build system based around converting autogen from a bash script to a Perl program. Jeff has provided emails explaining the features contained in the change.
Please note that configure requirements on components HAVE CHANGED. For example. a configure.params file is no longer required in each component directory. See Jeff's emails for an explanation.

Sorry for the mid-day configure change folks; I meant to commit this
last night and forgot. :-(

Thanks to Jed Brown for noticing the issue. Fixes trac:2503.

* If < 0, it's an OPAL_ERR_* value
* If >= 0, it's the actual output value of the function
This is problematic for the OPAL_SOS stuff. This commit changes those
functions to always return OPAL_* statuses and send the output value
back through output parameters (like 95% of the rest of the code
base). This avoids the confusion with OPAL_SOS stuff and makes
paffinity work again (e.g., mpirun --bind-to-core ...).
I updated all paffinitiy modules for the new function signatures, and
bumped the paffinity API version up to 2.0.1. I don't think the
version change will matter, though, because we'll be introducing
support for hardware threads soon, which will either bump the
paffinity version again or we'll replace paffinity with
a new framework.

I forgot to mention one more thing in the r23152 commit message:
* Copy the fix for hwloc's m4 to disable the configure flag
--enable-debug when building in embedding mode, because it can be
hijacked by the outter-level application. In this case, if you
configured OMPI with --enable-debug (or have --enable-debug in a
platform file), you'd see all of hwloc's debug output. Ick. hwloc
1.0 will include this fix.

supports a wide variety of operating systems and platforms; see the
opal/mca/paffinity/hwloc/hwloc/README file for details.
This component includes an embedded copy of hwloc, currently based on
hwloc-1.0rc6. But note that hwloc is properly SVN imported into the
/vendor branch, so it will be easy to update when 1.0 GA is released.
Note that the hwloc tree embedded in opal/mca/paffinity/hwloc/hwloc is
identical to a hwloc distribution tarball, except that much of the
documentation was rm -rf'ed (because we don't need it for the embedded
case).
Since the paffinity framework currently does not understand hardware
threads, the hwloc component compensates for this by identifying cores
by the "first" hardware thread on that core. Hopefully we'll update
paffinity someday to understand hardware threads. :-)
configure grew a --with-hwloc option, analogous to what we do for many
other external libraries that OMPI supports. However, there's a new
feature: due to the request of several distros, OMPI can be configured
to build with its internal copy of hwloc or with an external copy of
hwloc (e.g., a system-installed hwloc).
1. If --with-hwloc is not specified, Open MPI will try to use its
internal copy (but silently fail/ignore hwloc if that fails).
1. If --with-hwloc=<dir> is supplied, Open MPI looks for hwloc
support in <dir> (and --with-hwloc-libdir=<dir>, if specified).
1. If --with-hwloc=external is supplied, Open MPI will look for hwloc
in a compiler/linker default external location.
1. If --with-hwloc=internal is supplied, Open MPI will use its
internal copy of hwloc.
Some of OMPI's main configury had to be slightly re-arranged in the
bootstrapping phase to accomodate hwloc's configry needs.
