8b720093a8 wipe out tty buffer contents after read, to avoid keeping possibly 
sensitive information in memory longer than necessary
(We could make this depend on ~ECHO or so, but this would be an API
change and I don't think it is worth the effort.)

7db1d33cba Modify the licences of code written by Theo De Raadt from a 4-clause 
to a 2-clause licence (retaining UCB clauses (1) and (2)), per PR
22409 from Joel Baker, approved by Theo de Raadt, and ratified by
myself - the only discrepancy being the handling of the original
clause 3 in src/usr.sbin/yppoll/yppoll.c.

b193480908 Add extensible malloc types, adapted from FreeBSD. This turns 
malloc types into a structure, a pointer to which is passed around,
instead of an int constant.  Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.

ef6504281a remove duplicate prototypes from tty_subr.c (ndqb, putc, b_to_q), and 
make the first arg of b_to_q (the u_char * that points to data to be
stuffed into the queue) const, since it's not modified.

a0a7429482 lots of changes: prototype migration, move lots of variables, definitions, 
and structure elements around.  kill some unnecessary type and macro
definitions.  standardize clock handling.  More changes than you'd want.

41b03a4a6e Change tty code to use clist interface, but with ring buffer implementation. 
Also, fix a couple of bugs in tty.c and pccons.c, and some gross kluginess
in the hp300 stuff.
