Jeff Squyres 0ba47105ed Merge the /tmp/jms-installdirs-trunk branch into the trunk. This
finally brings in functionality that is already on the 1.2 branch, and
was developed and tested in the v1.2ofed branch (and other places).

Short version of new features:

 * Support for ibv_fork_init() 
 * Automatically fill in the openib BTL bandwidth value by 
   querying the HCA port 
 * Installdirs functionality 
 * Fixes to always use -I in the Fortran wrapper compilers (#924) 
 * Gleb's mpool updates 
 * Remove some kruft in btl/openib/configure.m4, therefore 
   fixing the harmless warnings noted in #665 
 * Bunches of updates to the Linux RPM spec file 

I.e., effectively the same thing that r14411 brought to the v1.2
branch.

Also effectively brought in r14432 and r14433 (some fixes on top of
the original r14411 commit to v1.2).  Still need to bring in the moral
equivalent of r14445 after this commit (fixes to installdirs).

This commit was SVN r14449.
