17eb1bfcbf Add 'hwatch' and 'dhwatch' ddb commands analogous to 'watch' and
'dwatch'.  The new commands install hardware watchpoints if supported
by the architecture and if there are enough registers to cover the
desired memory area.

869029d5d7 A set of changes to reduce the number of include files the kernel
takes from /usr/include. I cannot check them on alpha.. (will try beast)

f10fa038c1 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.

e8f4fc4a1d 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.

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

6145ccc494 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().

ed3ff9247c Completed function declarations and/or added prototypes and/or #includes
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.

4d4250da00 1) Changed ddb into a option rather than a pseudo-device (use options DDB
in your kernel config now).
2) Added ps ddb function from 1.1.5. Cleaned it up a bit and moved into its
   own file.
3) Added \r handing in db_printf.
4) Added missing memory usage stats to statclock().
5) Added dummy function to pseudo_set so it will be emitted if there
   are no other pseudo declarations.

f9fc827448 Fix up some sloppy coding practices:
- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
  header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.

NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.

07e1c7f69d Change all #includes to follow the current Berkeley style. Some of these
``changes'' are actually not changes at all, but CVS sometimes has trouble
telling the difference.

This also includes support for second-directory compiles.  This is not
quite complete yet, as `config' doesn't yet do the right thing.  You can
still make it work trivially, however, by doing the following:

rm /sys/compile
mkdir /usr/obj/sys/compile
ln -s M-. /sys/compile
cd /sys/i386/conf
config MYKERNEL
cd ../../compile/MYKERNEL
ln -s /sys @
rm machine
