This is a fairly intrusive change, but outside of the moving of opal/event to opal/mca/event, the only changes involved (a) changing all calls to opal_event functions to reflect the new framework instead, and (b) ensuring that all opal_event_t objects are properly constructed since they are now true opal_objects.
Note: Shiqing has just returned from vacation and has not yet had a chance to complete the Windows integration. Thus, this commit almost certainly breaks Windows support on the trunk. However, I want this to have a chance to soak for as long as possible before I become less available a week from today (going to be at a class for 5 days, and thus will only be sparingly available) so we can find and fix any problems.
Biggest change is moving the libevent code from opal/event to a new opal/mca/event framework. This was done to make it much easier to update libevent in the future. New versions can be inserted as a new component and tested in parallel with the current version until validated, then we can remove the earlier version if we so choose. This is a statically built framework ala installdirs, so only one component will build at a time. There is no selection logic - the sole compiled component simply loads its function pointers into the opal_event struct.
I have gone thru the code base and converted all the libevent calls I could find. However, I cannot compile nor test every environment. It is therefore quite likely that errors remain in the system. Please keep an eye open for two things:
1. compile-time errors: these will be obvious as calls to the old functions (e.g., opal_evtimer_new) must be replaced by the new framework APIs (e.g., opal_event.evtimer_new)
2. run-time errors: these will likely show up as segfaults due to missing constructors on opal_event_t objects. It appears that it became a typical practice for people to "init" an opal_event_t by simply using memset to zero it out. This will no longer work - you must either OBJ_NEW or OBJ_CONSTRUCT an opal_event_t. I tried to catch these cases, but may have missed some. Believe me, you'll know when you hit it.
There is also the issue of the new libevent "no recursion" behavior. As I described on a recent email, we will have to discuss this and figure out what, if anything, we need to do.

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.

sure the compilers could handle it.

instead of using the pre-processor in the header files.
A functional change is (re-) specifying __opal_attribute_noreturn__
on orte_errmgr_base_abort(): All modules in the errmgr framework
either use this function, or define their own abort function,
which sets __opal_attribute_noreturn__.
This attributes was taken out with the errmgr overhaul in r22872.

#define CACHE_LINE_SIZE to 128. This name has a conflict on NetBSD,
and it seems kinda odd to have a header file that ''only'' defines a
single value. Also, we'll soon be raising hwloc to be a first-class
item, so having this file around seemed kinda weird.
Therefore, I replaced CACHE_LINE_SIZE with opal_cache_line_size, an
int (in opal/runtime/opal_init.c and opal/runtime/opal.h) on the
rationale that we can fill this in at runtime with hwloc info (trunk
and v1.5/beyond, only). The only place we ''needed'' a compile-time
CACHE_LINE_SIZE was in the BTL SM (for struct padding), so I made a
new BTL_SM_ preprocessor macro with the old CACHE_LINE_SIZE value
(128). That use isn't suitable for run-time hwloc information,
anyway.

* Remove OPAL_ERR_PAFFINITY_NOT_SUPPORTED; fit it into the generic
OPAL_ERR_NOT_SUPPORTED case.
* When odls_default detects that processor affinity is not supported,
it prints a specific message about it, and then it suppressed a
generic HNP help message that would normally follow it (i.e., it's
easier to have the "processor affinity is not supported" show_help
message last).
* Use some symbolic names in odls_default instead of fixed int's,
just for slight readability improvements in the code.
* Introduce orte_show_help_suppress(), which gives the ability to
suppress any future showings of any arbitrary show_help() message.
This is useful if you display message X and want to suppress
message Y. This suppression *only* works in environments where
orte_show_help() does coalescing.

It is okay to not have a paffinity module IF you aren't using paffinity anyway. So don't error out of MPI_Init because a paffinity module wasn't selected.
Cleanup error reporting in the odls default module to (once and for all!) eliminate messages originating in the fork'd process. Create some new error codes to allow us to pass enough info back to the parent process to provide useful error messages.

Remove the --enable-progress-threads option as this is no longer functional, and hardcode OPAL_ENABLE_PROGRESS_THREADS to 0.
Replace the --enable-mpi-threads option with --enable-mpi-thread-multiple as this is clearer as to meaning. This option automatically turns "on" opal thread support if it wasn't already so specified. If the user specifies --disable-opal-multi-threads --enable-mpi-thread-multiple, we will error out with a message
Add a new --enable-opal-multi-threads option that turns "on" opal thread support without doing anything wrt mpi-thread-multiple

C++ compiler in configure. If we have a C++ compiler, then the MPI
C++ bindings are built by default. If we don't have a C++ compiler,
then the MPI C++ bindings are not built by default.
--enable-mpi-cxx will now force an error if there is no C++ compiler
available. --disable-mpi-cxx (or the lack of a C++ compiler) will now
disable many of the C++ compiler checks in configure.
Note that there are a few items to clean up regarding the difference
between C's _Bool type and C++'s bool type. Right now, we assume that
they are the same. But they aren't, and they shouldn't be treated as
such. This cleanup will be forced in MPI-2.2 with the introduction of
the MPI_C_BOOL MPI datatype.

Studio compilers again. It has been broken since
1/14/2009 when some changes exposed a bug in autoconf
and how it handles support for the restrict keyword.
Basically, Sun Studio C supports the restrict keyword
but Sun Studio C++ does not.
I am also pursuing a fix with the autoconf folks, but
this change was needed to get things building again.

* The opal_sys_timer_get_cycles() call was implemented for
Sparc v9 using inline assembly, but not in the assembly files.
This would only currently matter on Linux Sparc systems using
a compiler that didn't support inline assembly (not many of
those), but it should be there for completion.
* The linux timer component would always build on non-Alpha
platforms, rather than only building on platforms where
opal_sys_timer_get_cycles() was implemented. This would
only matter on a very narrow set of platforms that we don't
really support, but still, it could be more right. We now
only build the component on platforms where we have the
assembly call to get the cycle counter.
* Added a comment to opal/sys/timer.h to note that the linux
timer component needed to be updated if another platform was
added.
This should be harmless to commit. It will only really change
behaviors on platforms we don't have assembly support for, which
currently won't make it through configure. It really only matters
when (if?) we support atomic operations through libatomic_ops.
