than $(LN_S). This causes problems with with Windows and probably
elsewhere (re: #200). So use a slightly different trick to get the
right header selected for the MEMCPY and TIMER components.
* Using the same trick used to solve the AC_CONFIG_LINKS problem,
stop using a separate header file for direct calling in the
PML and MTL. This lets me remove some icky code in ompi_mca.m4
that was more fragile than I really liked.

Keeping the cache misses as low as possible is always a good approach.
The opal_list_t is widely used, it should be a highly optimized class.
The same functionality can be reached with one one sentinel instead
of 2 currently used.
I don't have anything against the STL version, but so far nothing can
compare with the Knuth algorithm. I replace the current implementation
with a modified version of the Knuth algorithm (the one described in
The Art of Computer Programming). As expected, the latency went down.

- orte-clean.c : check to see if the base session directory is empty
and delete it if it is.
- orte_universe_exists.c : Fix a down stread problem resulting from
George's r10718 commit. Don't use the 'fulldirpath' since
that is no longer guarenteed to be the absolute path
to the session directory. Construct this value outside of that
function from the prefix and frontend vars.

After seeing the uglyness that is removing directories in the
codebase I decided to push down this to the OPAL by extending the
opal/os_create_dirpath.(c|h) to contain some more functionality.
In this process I renamed 'os_create_dirpath' to 'os_dirpath' since it
is a bit more general now.
Added a few functions to:
- check if an directory is empty
- check to see if the access permissions are set correctly
- destroy the directory at the end of the dirpath
- By using a caller callback function (a la Perl, I believe)
for every file, the caller can have fine grained control over
whether a specific file is deleted or not.
This simplifies things a bit for orte_session_dir_(finalize|cleanup)
as it should no longer contain any of this functionality, but uses
these functions to do the work.
From the external perspective nothing has changed, from the
developer point of view we have some cleaner, more generic code.

opal_free_list_item_t and everyone was just treating them as
opal_list_itme_t structures, which meant that they were overwriting the
user_data memory anyway. So make an opal_free_lsit_item_t be just a
opal_list_item_t.
Also, opal_free_list_item_t wasn't a proper class, which made it slightly
less than nice to use, so fix that part up. Also update the
opal_free_list_t to use the class macros, so that it is more obvious we
actually do the right thing.

reentrant for free(), so we can't call free() from inside an sbrk() handler.
The solution is never call sbrk() with a negative number. The mmap() allocator
used for large allocations does not have this problem and continues to give
memory back to the OS as soon as possible.
This should go to both the v1.1 and v1.0 branches.

therefore people interested in using the high performance memcpy
should use directly opal_memcpy instead. Notice, that there are 2
other versions of memcpy available, which use a destination or a source

Previous rev. maintained state on the communicator used for acking duplicate
fragments, but the communicator may be destroyed prior to successfull
delivery of an ack to the peer. We must therefore maintain this state
globally on a per peer, not a per peer, per communicator basis.
This requires that we use a global rank on the wire and translate this as
appropriate to a local rank within the communicator.
