47e40520dd Do not try to work around ``poor (un)sign extension code''
creation by GCC-2.6.3.  Casting pointers to unsigned char
to volatile pointers to unsigned char seemed to produce
better results on the ia32 architecture with old versions
of GCC.
The current FreeBSD system compiler GCC-3.2.1 emits
better sign extension code for non-volatile variables:

volatile char c;
int i = c;

is compiled to:
...
movb	-1(%ebp), %al
movbsl	%al, %eax
movl	%eax, -8(%ebp)
...

char c;
int i = c;

is compiled to:
...
movbsl	-1(%ebp), %eax
movl	%eax, -8(%ebp)
...

The same holds for zero-extension of dereferenced pointers
to volatile unsigned char.
When compiled on alpha or sparc64, the code produced for the
two examples above does not differ.

37c841831f Be consistent about "static" functions: if the function is marked
static in its prototype, mark it static at the definition too.

f457830b8e de-count schistory.c. The handling of NSC was rather bogus here and was
little more than a place holder, because nothing actually counted the
number of 'sc' units to compare it against NSC.  A bit more work here
is needed so that the scaling of SC_MAX_HISTORY_SIZE and extra_history_size
goes up when more sc units are added.  But, it does not appear that we can
have more than one console yet, so it does not seem particularly urgent.

ce907d4246 Add a VT_LOCKSWITCH ioctl that disallows vty switching. Something
like this can be emulated by VT_SETMODEing to VT_PROCESS and never
releasing the vty, but this has a number of problems, most notably
that a process must stay resident for the lock to be in effect.

de4dc9595e Add some functionality via sysctl to syscons.
hw.syscons.saver.keybonly: used to specify that only input is to
interrupt the screensaver.  This allows one to run a chatty console
app but still have the screen blank out until a key is pressed.
There should probably also be an ioctl for this, we'll do that later.

hw.syscons.saver.blanktime: exports the screensaver timeout via sysctl.

44731cab3b Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

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.

f9390180fe Some fix for the recent apm module changes.
- Now that apm loadable module can inform its existence to other kernel
   components  (e.g. i386/isa/clock.c:startrtclock()'s TCS hack).
 - Exchange priority of SI_SUB_CPU and SI_SUB_KLD for above purpose.
 - Add simple arbitration mechanism for APM vs. ACPI.  This prevents
   the kernel enables both of them.
 - Remove obsolete `#ifdef DEV_APM' related code.
 - Add abstracted interface for Powermanagement operations.  Public apm(4)
   functions, such as apm_suspend(), should be replaced new interfaces.
   Currently only power_pm_suspend (successor of apm_suspend) is implemented.

78f45204d9 Introduce new syscons(4) kernel options:
- SC_CUT_SPACES2TABS - when copying text into the cut buffer convert leading
  spaces into the tabs;
- SC_CUT_SEPCHARS="XYZ" - treat supplied characters as possible words
  separators when the driver searches for words boundaries when doing cut
  operation.

Also unify cut code a bit to decrease amount of duplicated code. This fixes
line cut mode, so that it is no longer pads line with useless spaces.
