Nathan Hjelm c954f457d9 mca/base: update the way dynamic components are handled
This commit is a rework of the component repository. The changes
included in this commit are:

 - Remove the component dependency code based off .ompi_info
   files. This code is legacy code dating back 10 years that and is no
   longer used.

 - Move the plugin scanning code to the component repository. New
   calls have been added to add new scanning paths, query available
   components, and dlopen/load components.

 - Pass the framework down to mca_base_component_find/filter. Eventually
   the framework structure will be used to further validate components
   before they are used.

 - Add support to the MCA framework system to disable scanning for
   dlopened components on open (support already existed in
   register). This is really only relevant to installdirs as it has no
   register function and no DSO components.
