investivating #817:
* Remove use of legal_numbits member and always just use the full
size of the array. There was a corner case where legal_numbits was
not an even multiple of the number of bits in the array where bits
would not get freed properly, ususally causing wasted fortran
MPI handles, or, as in the case of #817, wasted attribute keyvals
(i.e., the user freed them, but the bitmap didn't reflect the
free).
* Re-order some error checks to ensure that we don't segv (we don't
currently trigger this problem anywhere; I just noticed it while
doing the other attribute keyval and legal_numbits work).
Since this change affects all Fortran MPI handles, I ran all the intel
and ibm tests and all still pass with this change.

- Set ompi-specific autoconf cache-variables
- Implement one function to check for availability of an
attribute with the possibility for a cross-check.
- Do cross-checks for
__attribute__(format)
__attribute__(nonnull)
__attribute__(sentinel)
__attribute__(warn_unused_result)
- Grep the compilers warnings for keywords regarding ignored
attributes.
- Include also the no_instrument_function

This change utilizes the new num_processors function. I also left the mods made to ompi_mpi_init and the bug fix for the default value of mpi_yield_when_idle. Note that the mods to mpi_init will not really take effect as the mca param will now *always* be set (either by user or odls). We will need those mods later, so no point in removing them now.

Add new function opal_get_num_processors() that will return the number
of processors on the local host. Does the Right thing in POSIX
environments (to include a special case for OS X), and will shortly do
the Right Thing for Windows (this commit includes a change to
configure, so I wanted to get that in before the US workday -- the
Windows code can some shortly because it won't involve configury
changes).

The following Trac tickets were found above:
Ticket 853 --> https://svn.open-mpi.org/trac/ompi/ticket/853
a protection against creating subarrays with MPI_LB and MPI_UB. But, I don't
think the MPI standard state anything about this.

go and have proper casting.
Tested with linux gcc-4, icc-9.0, pathcc-2.2.1 and pgi-6.2.5
(icc warns on several attributes, that they are ignored;
same for pathcc and pgi)
This commit was SVN r13485.
Check both the c and cpp compilers for support of attributes, and then check for support for each individual attribute with both compilers. Only if both compilers support a given attribute will we enable it.

remote nodes. It will also kill off rogue orteds and orterun
processes. The killing of processes is ifdef'ed out for Windows
since I do not know how to do it there. Note that this change
will requite an autogen.

* Separate out test clauses; don't have the same guarantees of
left-to-right evaluation in shell script that you do in other
languages (i.e., protect against the case of running "basename ''")

The step used to iterate through buffer was function of true_extent instead of extent.
This may or may not solve ticket #689 because I am still getting failures over btl mx,
but I cannot reproduce failures over mtl mx nor tcp.
