grn_normalizer_register() registers a normalizer to the database
which is associated with `ctx'. `name_ptr' and `name_length' specify
the normalizer name. `name_length' can be `-1'. `-1' means that
`name_ptr` is NULL-terminated. Alphabetic letters ('A'-'Z' and
'a'-'z'), digits ('0'-'9') and an underscore ('_') are capable
characters. `init', `next' and `fin' specify the normalizer
functions. `init' is called for initializing a tokenizer for a
document or query. `next' is called for extracting tokens one by
one. `fin' is called for finalizing a
tokenizer. grn_tokenizer_register() returns GRN_SUCCESS on success,
an error code on failure. See "groonga.h" for more details of
grn_proc_func and grn_user_data, that is used as an argument of
grn_proc_func.
