35e61cbd71 Add a new mechanism, cndbctl(), to tell the console driver that
ddb is entered.  Don't refer to `in_Debugger' to see if we
are in the debugger.  (The variable used to be static in Debugger()
and wasn't updated if ddb is entered via traps and panic anyway.)

- Don't refer to `in_Debugger'.
- Add `db_active' to i386/i386/db_interface.d (as in
  alpha/alpha/db_interface.c).
- Remove cnpollc() stub from ddb/db_input.c.
- Add the dbctl function to syscons, pcvt, and sio. (The function for
  pcvt and sio is noop at the moment.)

Jointly developed by: bde and me

(The final version was tweaked by me and not reviewed by bde.  Thus,
if there is any error in this commit, that is entirely of mine, not
his.)

3000820ae0 add some amount of sanity to the way the gdb stuff finds its device.
I'm not too happy about the result either, but at least it has less
chance of backfiring.

This particular feature could be called "a mess" without offending
anybody.

a1c1e16ada Changes to support -Wall, -Wcast-qual. Had to make physical code changes
in db_lookup() to avoid the *cp = 0 / *cp = ':' combo ( temporary
    nul-terminate-then-restore-original ) on a const char * string.

748993b899 Added macros __printflike() and __scanflike() to <sys/cdefs.h>.
Use them to `make gcc -Wformat' check formats for all printf-like
and scanf-like functions in /usr/src except for the err()/warn()
family.  err() isn't quite printf-like since its format arg can
legitimately be NULL.  syslog() isn't quite printf-like, but gcc
already accepts %m, even for plain printf() when it shouldn't.

3da6ef3c3a Fixed bogus type of valuep in struct db_variable. It was `int *' and
became `long *' for alpha, but should always have been `db_expr_t *'.
Fixed variable types to match.

ecbb00a262 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

b7aa38c1e3 Ensure that the linker sets for commands exist by putting a standard
command in each of them.  This removes the need for hard-to-configure
dummy instantiations of the sets.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

6337f4efa8 Support statically attaching of ddb commands in non-ddb modules.
The details are hidden in the DB_COMMAND(cmd_name, func_name) and
DB_SHOW_COMMAND(cmd_name, func_name) macros.  DB_COMMAND() adds to
the top-level ddb command table and DB_SHOW_COMMAND adds to the
`show' subtable.  Most external commands will probably be `show'
commands with no side effects.  They should check their pointer
args more carefully than `show map' :-), or ddb should trap internal
faults better (like it does for memory accesses).

The vm ddb commands are temporarily unattached.

ddb.h:
Also declare `db_indent' and db_iprintf() which will replace vm's
`indent' and iprintf().

e00fb8aaea Woops, wrong solution to the problem. Backed out previous fix to ddb.h, and
nuked the db_printf() declaration from db_output.h.
