* config/atof-vax.c (md_atof): Return null on success instead of
empty string.
* config/atof-tahoe.c (md_atof): Ditto.
* read.c (float_cons): Expect a null pointer for success, not an
empty string.
* hash.c (hash_insert, hash_jam, hash_grow): Return null pointer
on success, instead of empty string. All callers changed.
* config/tc-vax.c: Use PARAMS in declarations.
(vip_op): Use NULL instead of empty string for success in error
and warning fields.
