Ticket 1435 --> https://svn.open-mpi.org/trac/ompi/ticket/1435
* Fix linux paffinity component to make a "best" guess when PLPA
can't find topology information in the Linux kernel. That is, if
PLPA can't tell us the max_processor_id, just assume that it's the
same as the number of processors. If you have a more complex
system than that (e.g., you have holes in your available processor
IDs), you'll likely be running a Linux kernel that supports the
topology information, and this problem won't happen.
* Make sure to conver the return codes from PLPA to OPAL_ERR* codes.

Any components not in the trunk, but in one of the effected frameworks *must* be
updated. Contact the list, look at the RFC, or look at the diff for how to do this.
Sorry for the early commit of this, but I wanted to get it in today (per RFC) and
didn't know if I would have a chance later today.

Changes paffinity interface to use a cpu mask for available/preferred cpus
rather than the current coarse grained paffinity that lets the OS choose
which processor.
Macros for setting and clearing masks are provided.
Solaris and windows changes have not been made. Solaris subdirectory has some
suggested changes - however the relevant man pages for the Solaris 10 APIs
have some ambiguity regarding order in which one create and sets a processor
set. As we did not have access to a solaris 10 machine we could not test to
see the correct way to do the work under solaris.

So define the constant if it isn't already defined. Something else
includes stdio.h, which has a bunch of declarations that really
confuse non-GNU compilers, so be sure to include that one before
setting __USE_GNU.

- 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)

all the different cases (curses to RedHat for continually changing
the glibc API!)
- Minor fixes for the Solaris paffinity component
This commit was SVN r6894.
- Simple components for getting and setting processor affinity of a
process; does *not* include scheduling decisions
- No one in the OMPI code base invokes the framework yet
- Added linux component for using sched_setaffinity()
- Added shell solaris component that will use processor_bind()
(currently .ompi_ignore'd)
