Ralph Castain 9ea2b196ce Convert the opal_event framework to use direct function calls instead of hiding functions behind function pointers. Eliminate the opal_object_t abstraction of libevent's event struct so it can be directly passed to the libevent functions.
Note: the ompi_check_libfca.m4 file had to be modified to avoid it stomping on global CPPFLAGS and the like. The file was also relocated to the ompi/config directory as it pertains solely to an ompi-layer component.

Forgive the mid-day configure change, but I know Shiqing is working the windows issues and don't want to cause him unnecessary redo work.

This commit was SVN r23966.
