This commit adds a access_flags argument to the mpool registration function. This flag indicates what kind of access is being requested: local write, remote read, remote write, and remote atomic. The values of the registration access flags in the btl are tied to the new flags in the mpool. All mpools have been updated to include the new argument but only the grdma and udreg mpools have been updated to make use of the access flags. In both mpools existing registrations are checked for sufficient access before being returned. If a registration does not contain sufficient access it is marked as invalid and a new registration is generated. Signed-off-by: Nathan Hjelm <hjelmn@lanl.gov>
