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.

f41325db5f With this commit, I hereby pronounce gensetdefs past its use-by date.
Replace the a.out emulation of 'struct linker_set' with something
a little more flexible.  <sys/linker_set.h> now provides macros for
accessing elements and completely hides the implementation.

The linker_set.h macros have been on the back burner in various
forms since 1998 and has ideas and code from Mike Smith (SET_FOREACH()),
John Polstra (ELF clue) and myself (cleaned up API and the conversion
of the rest of the kernel to use it).

The macros declare a strongly typed set.  They return elements with the
type that you declare the set with, rather than a generic void *.

For ELF, we use the magic ld symbols (__start_<setname> and
__stop_<setname>).  Thanks to Richard Henderson <rth@redhat.com> for the
trick about how to force ld to provide them for kld's.

For a.out, we use the old linker_set struct.

NOTE: the item lists are no longer null terminated.  This is why
the code impact is high in certain areas.

The runtime linker has a new method to find the linker set
boundaries depending on which backend format is in use.

linker sets are still module/kld unfriendly and should never be used
for anything that may be modular one day.

83d94cdf69 In the VIRTUAL_TTY macro, add a check to make sure that the result of
SC_DEV isn't NULL; if it is, evaluate to NULL and don't dereference
NULL.  Callers of VIRTUAL_TTY must already check for the result being
NULL since si_tty can be NULL, so this should be safe.

This fixes a panic when trying to switch to a different vty in an
environment such as userconfig (-c option to the kernel).
