perm, rperm, comb, rcomb: test generic sequences, bugfixes.

perm doesn't generate items of the right type. We need
to add the original sequence to the state vector and
use make_like.

The new generic sequence support in rperm is broken, too.

* combi.c (perm_while_fun, perm_gen_fun_common): Rename p
variable to vec.
(perm_init_common): Rename to perm_init. Take one more
argument and store in new fourth element of state vector.
(perm_vec, perm_list, perm_str): Pass nil to new parameter
of perm_init.
(perm_seq_gen_fun): Use perm_list_gen_fun to get list
permutations, and coerce each one to the same type as
the sequence with make_like.
(rcomb_seq_gen_fun): Remove redundant call to
rcomb_gen_fun_common. The rcomb_list_gen_fun function
is called, which does this already, so we lose every
other sequence element.

* tests/015/comb.tl: New tests.
