2b8b744edf 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.

16e3fbd2c1 Suser() simplification:
1:
  s/suser/suser_xxx/

2:
  Add new function: suser(struct proc *), prototyped in <sys/proc.h>.

3:
  s/suser_xxx(\([a-zA-Z0-9_]*\)->p_ucred, \&\1->p_acflag)/suser(\1)/

The remaining suser_xxx() calls will be scrutinized and dealt with
later.

There may be some unneeded #include <sys/cred.h>, but they are left
as an exercise for Bruce.

More changes to the suser() API will come along with the "jail" code.

e7c3d728c1 Fix the broken VT_WAITACTIVE ioctl for the case where the third arg
was 0.

PR:		4164
Submitted by:	Joe Traister <traister@mojozone.org>

While i was at it, also fixed a broken return value for the VT_RELDISP
ioctl, iff the third arg was legally VT_TRUE, but the destination
screen was in process mode so the actual switch had to be deferred.
This was breaking the ability to directly toggle between two X servers
running on two VTs, since the server getting the bogus error return
was running wild, and competing with the other one for the hardware.
(Sigh, this was a very long-standing bug.)

adcb62ea36 Finished (?) converting md_regs to a `struct trapframe *'. Some bogus casts
are now unnecessary.

2a670d60f7 Fixed struct access bug and style bugs in previous revision. The same
fix as for syscons did not work because pcvt uses a struct where syscons
uses a struct pointer.

0a4f73a54d add the same fix to pcvt that I did to syscons. Make sure that the signals
provided by the user are valid else return EINVAL.

2feff74c28 Implement a simple hook (or hack?) to allow graphics device console
drivers to protect DDB from being invoked while the console is in
process-controlled (i.e., graphics) mode.

Implement the logic to use this hook from within pcvt.  (I'm sure
Søren will do the syscons part RSN).

I've still got one occasion where the system stalled, but my attempts
to trigger the situation artificially resulted int the expected
behaviour.  It's hard to track bugs without the console and DDB
available. :-/

96f56f5d20 Correct a few minor things in pcvt:
o  the includes are now properly done by <sys/foo.h> instead of "foo.h"
o  a bunch of undeclared functions has been resolved
o  pcvt finally supports devconfig
