math/metis. Because math/metis and math/metis-edf are conflicting, this means
that the ports which depend on SuiteSparse and on metis-edf became BROKEN.
To solve this problem, this revision adds the missings includes brought by
metis-edf to metis.
Note for myself: if everything goes well, do not forget to deprecate the port
math/metis-edf in a near future.
CONFLICTS, LATEST_LINK, and PORTSCOUT; adjust dependent ports; explicitly
note the restrictive license of the metis ports (while here, append the MPI port to
*DEPENDS in math/parmetis, rather than using an assignment)
