libfshelp: Use node instead of name as key.

Previously, libfshelp used the name of an translator as key in the
hash table.  This however is flawed, because a translator is bound to
a node, and a node can have zero or more links in the file system.
Use the nodes address (or rather, the address of the transbox embedded
in the node) as key instead.

* libfshelp/fshelp.h (fshelp_set_active_translator): Instead of the
control port, hand the whole transbox to the function.
* libfshelp/translator-list.c (struct translator): New field 'locp'.
(hash): Hash pointer.
(compare): Compare pointer.
(translator_ihash): Use an location pointer.
(fshelp_set_active_translator): Use the address of the transbox as key.
(fshelp_remove_active_translator): Remove using the location pointer.
* libdiskfs/dir-lookup.c (diskfs_S_dir_lookup): Fix callsite.
* libdiskfs/file-set-trans.c (diskfs_S_file_set_translator): Likewise.
* libnetfs/dir-lookup.c (netfs_S_dir_lookup): Likewise.
* libnetfs/file-set-translator.c (netfs_S_file_set_translator):
Likewise.
