patch

_cairo_hash_table_insert can use key_unique = TRUE when calling
_cairo_hash_table_lookup_internal because the rules don't permit inserting an
entry with an existing key.

This saves on having to search through dead entries (as the first dead can be
used), and means that the cairo_hash_keys_equal_func_t need not be called on
live entries.
