This commit adds an owner file in each of the component directories
for each framework. This allows for a simple script to parse
the contents of the files and generate, among other things, tables
to be used on the project's wiki page. Currently there are two
"fields" in the file, an owner and a status. A tool to parse
the files and generate tables for the wiki page will be added
in a subsequent commit.
As pointed out by @ggouaillardet, we were adding some unnecessary -I
flags to CPPFLAFGS when --without-hwloc was being used. This commit
slightly updates the hwloc191 component configury to only add such
things when the component is, in fact, going to be
compiled/installed.
