f591779bb5 Lock struct pgrp, session and sigio.
New locks are:

- pgrpsess_lock which locks the whole pgrps and sessions,
- pg_mtx which protects the pgrp members, and
- s_mtx which protects the session members.

Please refer to sys/proc.h for the coverage of these locks.

Changes on the pgrp/session interface:

- pgfind() needs the pgrpsess_lock held.

- The caller of enterpgrp() is responsible to allocate a new pgrp and
  session.

- Call enterthispgrp() in order to enter an existing pgrp.

- pgsignal() requires a pgrp lock held.

2c2bb10f49 No-op change. Remove #if NVT > 0 in files that are 'optional vt' and
therefore can never be compiled if NVT == 0. config(8) guarantees this.

191293e031 Substantially cleanup of the pcvt kernel part. This cleanup does
not introduce (hopefully) any functional changes but gets rid of
the #ifdef spaghetti pcvt suffered from more and more over the
years.

Several no more used parts of the source were removed, others
which are used by default are now non-optional components:

PCVT_NETBSD		removed completety
PCVT_FREEBSD		removed option, code is now standard
PCVT_KBD_FIFO		removed option, code is now standard
PCVT_EMU_MOUSE		removed completety
PCVT_SW0CNOUTP		removed completety
PCVT_PORTIO_DELAY	obsolete, removed
PCVT_KEYBDID		removed option, code is now standard
PCVT_SIGWINCH		removed option, code is now standard
PCVT_PALFLICKER		removed completety
PCVT_WAITRETRACE	removed completety
PCVT_NOFASTSCROLL	removed option, code is now standard
PCVT_USL_VT_COMPAT	removed the "old" non-vt Xserver code completely,
			depending on XSERVER, this code is now standard.

Pcvt userland cleanup will follow as well as newbusifying the
kernel part.

a8d08723fb Implement scrollback for pcvt based on code submitted by
Aaron Campbell <aaron@cs.dal.ca>.

Use SHIFT-PgUp and SHIFT-PgDn to scroll back and forward.

Aarons original code was enhanced to have a separate scrollbuffer
for every virtual terminal and to preserve the screen contents
when switching screen sizes.

The scrollbuffer size is currently fixed at 8 pages but this
will be made configurable through the use of scon(1) in the
near future.

For pcvt_kbd.h, a longstanding compiler warning was fixed by
using excessive backetizing of the key2ascii[] table.

db1ab08ec9 Correct handling of ASCII DEL (0x7F).
I don't have access to a real VT220 to verify this against.
However, I'm committing the patch in `good faith' because
(a) getting hold of a real VT220 is going to be increasingly difficult
    the longer the PR sits around,
(b) some one was troubled enough to in a PR and
(c) the fix is minor and has no other implications.

e843ad34c1 Fix a bogon in pcvt that caused a characterset designation to not take
effect immediately, but required a following (normally redundant) G0
into GL mapping.  This adds one layer of indirection (thus might make it
slower), but fixes the broken box character drawing in pcvt.

Hellmuth and Bruce are unfortunately too busy too review this right now,
but i wanna have it in 2.2 since it has often been asked in the past.

4441bd4c1b Avoid touching the LEDs too early in the game. After the recent
changes to the keyboard code in pcvt, this update_led() very often
caused pcvt to hang early at boot time.

(Eventually, a better solution should be found, but the simple
omission serves well as a workaround for something that is actually a
show-stopper class problem.)

Candidate for 2.2.

e7451974bb Make pcvt and syscons live in the same kernel. If both are enabled, then
the first one in the config has priority.  They can be switched using
userconfig().

i386/i386/conf.c:
Initialize the shared syscons/pcvt cdevsw entry to `nx'.

Add cdevsw registration functions.

Use devsw functions of the correct type if they exist.

i386/i386/cons.c:
Add renamed syscons entry points to constab.

i386/i386/cons.h:
Declare the renamed syscons entry points.

i386/i386/machdep.c:
Repeat console initialization after userconfig() in case the current
console has become wrong.  This depends on cn functions not wiring down
anything important.

sys/conf.h:
Declare new functions.

i386/isa/isa.[ch]:
Add a function to decide which display driver has priority.  Should be
done better.

i386/isa/syscons.c:
Rename pccn* -> sccn*.

Initialize CRTC start address in case the previous driver has moved it.

i386/isa/syscons.c, i386/isa/pcvt/*
Initialize the bogusly shared variable Crtat dynamically in case the
stored value was changed by the previous driver.

Initialize cdevsw table from a template.

Don't grab the console if another display driver has priority.

i386/isa/syscons.h, i386/isa/pcvt/pcvt_hdr.h:
Don't externally declare now-static cdevsw functions.

i386/isa/pcvt/pcvt_hdr.h:
Set the sensitive hardware flag so that pcvt doesn't always have lower
priority than syscons.  This also fixes the "stupid" detection of the
display after filling the display with text.

i386/isa/pcvt/pcvt_out.c:
Don't be confused the off-screen cursor offset 0xffff set by syscons.

kern/subr_xxx.c:
Add enough nxio/nodev/null devsw functions of the correct type for syscons
and pcvt.
