Also mark all printf-like funxions in libzfs_impl.h as printf-like and add --no-show-locs to storeabi, in hopes diffs will make more sense in future This removes these symbols from libzfs: D nfs_only T SHA256Init T SHA2Final T SHA2Init T SHA2Update T SHA384Init T SHA512Init D share_all_proto D smb_only T zfs_is_shared_proto W zpool_mount_datasets W zpool_unmount_datasets Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Reviewed-by: Matthew Ahrens <mahrens@delphix.com> Reviewed-by: John Kennedy <john.kennedy@delphix.com> Signed-off-by: Ahelenia Ziemiańska <nabijaczleweli@nabijaczleweli.xyz> Closes #12048
