- Introduce a sysctl to control the default tty queue size kern.tty.qsize,
...
which defaults to 1024 as before.
- Add two ioctls TIOC{G,S}QSIZE to read and adjust the queue size on
individual ptys.
NB: ttys (and ptys) still silently (or beepingly (IMAXBEL)) drop
characters if the queue size is exceeded. I.e. you can appear
to succeed writing to the {p,t}ty, but not all characters will
have made it if the queue overflows. CVS:

Christos was worried about clrbits() being called with a length of zero.
...
This can't happen, but rework so it doesn't matter.
Remove 'optimisation' for length 1, that doesn't happen often enough.

Fix clrbits() so that it doesn't mask no bits out of the byte after the
...
range (when the last bit to be cleared is the msb of a byte).
Fixes PR/42312 in a slightly better way than proposed.

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.)

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.

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.
