fix the streams used in opal_output in the sharedfp components.
Add option to disable building the OSHMEM interface.  This isn't perfect, but should work for the v1.7 timeframe
Changes to VT/OTF:
Fixed warnings about the need of the 'subdir-objects' option when using Automake v1.14.
Due to a bug in Automake (see http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13928) the 'subdir-objects' option cannot be enabled.
To get around this problem external sources files are sym linked in the current build directory (as done in ompi/mpi/c/profile) to lead Automake to believe that all source files are in the same directory.
add support for --without-oshmem in configure
Corrected svn:ignores
