due to perf opt.
2) Remove unneeded include.
3) An initialization assert added to malloc.

changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.
The system boots and can mount UFS filesystems.
Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
Mount_std mounts will not work until the getfsent
library routine is changed.

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.
`show vmopag', `show page' and `show pageq'. Moved all vm ddb stuff
to the ends of the vm source files.
Changed printf() to db_printf(), `indent' to db_indent, and iprintf()
to db_iprintf() in ddb commands. Moved db_indent and db_iprintf()
from vm to ddb.
vm_page.c:
Don't use __pure. Staticized.
db_output.c:
Reduced page width from 80 to 79 to inhibit double spacing for long
lines (there are still some problems if words are printed across
column 79).
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().
Emacs-style line editing has already been there (did anybody ever
notice this? :), so i `only' had to add ^P and ^N. The approach is
fairly minimalistic, with the advantage of keeping the bloat as small
as 864 bytes of .text and 16 bytes of .bss, plus 10*120 bytes
malloc'ed history buffer at the first use.
exit and cleanup. the 'ps' command assumes that there are always 'nproc'
processes on the lists and will walk off the end without checking if not,
causing ddb to trap during the 'ps' command.
Add more features to the one remaining to handle the job:
+ signed quantity.
# alternate format
- left padding
* read width as next arg.
n numeric in (argument specified) default radix.
Fix the DDB debugger to use these.
Use vprintf in debug routine in pcvt.
The warnings from gcc may become more wrong and intolerable because
of this.
Warning: I have not checked the entire source for unsupported or
changed constructs, but generally belive that there are only a few.

to get the prototypes.
Changed some `int's to `boolean_t's. boolean_t's are ints so they are
hard to distinguish from ints.
Converted function headers to old-style. ddb is written in K&R1 C
except where we broke it.
