libzfs: convert to -fvisibility=hidden

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
