tsleep() to be called from an interrupt handler.
The semantics of the scroll-lock key is changed now: it issues a ^S or
^Q, depending on the current state. (It should probably issue
tp->t_cc[VSTOP] or tp->t_cc[VSTART] instead, but this would require more
serious structural changes because there is not always a tty context
present.)
The "scroll lock" LED is now controlled by pcstart()/pcstop(), so it
will show the real state even if the start/stop characters are remapped
or the normal ^S/^Q are used.

Note that I only did this for the US type keyboard maps.
This and all other such options should be documented, and perhaps
rennamed with consistant PCCONS_ prefixes.
o option DISPLAY_ISO8859 enables the display of iso-latin1
character set (instead of the IBM page code 437)
o option FRENCH_KBD, GERMAN_KBD or NORVEGIAN_KBD implement
support for national keyboards (implies DISPLAY_ISO8859).

2) Add option PCCONS_REAL_BS which (for US keyboards only) forces
backspace to really be backspace and not delete. Intended to close
PR #2264 submitted by Greg Woods. He wanted it changed for everyone
-- I thought adding a kernel compile option was friendlier.
Note: Both of these sets of options really should be documented in an
i386 specific version of options(4).
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
which represents the "keyboard controller". Give "pc" and "vt" drivers
the "pckbd" attribute. In pcattach() (pccons and pcvt), attach children
of the keyboard controller.
Map kernel stacks only at unique addresses.
Use one TSS per process.
Add sysarch calls for modifying IOPL and the I/O permission bitmap.
Add a compacting GDT entry allocator, for TSS and LDT selectors.
Enable modifying %fs and %gs with PT_SETREGS.
Sanitize various bits of code.
