We need to make the find_veriexec_file() function available publicly, so rename it to mac_veriexec_metadata_find_file_info() and make it non-static. Bump the version of the veriexec device interface so user space will know the labelized version of fingerprint loading is available. Approved by: sjg Obtained from: Juniper Networks, Inc.
