Drop <bsd.man.mk> support from <bsd.kmod.mk>.

Not objected to by: -current

Use a consistent style and one much closer to the rest of /usr/src

Use .include <bsd.kmod.mk> to get to ../../*/conf/kmod.mk instead of
encoding the relative path.

Pull in sys/conf/kmod.mk, rather than /usr/share/mk/bsd.kmod.mk.
This means that the kernel can be totally self contained now and is not
dependent on the last buildworld to update /usr/share/mk. This might
also make it easier to build 5.x kernels on 4.0 boxes etc, assuming
gensetdefs and config(8) are updated.

Zap KMODDEPS line

Removed special rules for building and cleaning device interface files
and empty options files. The rules are now generated automatically in
bsd.kmod.mk. Cleaned up related things ($S and ${CLEANFILES}).

$Id$ -> $FreeBSD$

Make this work now; fixing the kstack overflow allows the dependency to
be added to the symbol search order safely.

Sample initial set of kld-ified modules. Not all have been completely
converted yet. These are more of a starting point. This is NOT connected
to the parent Makefile.

OK'ed by jkh (who is ever so patiently waiting)

Shut this thing up, like the other LKMs

The coff LKM needs IBCS2 to be able to link (for the 'make regress'
linktest) - add this as a dependency.

Don't put "-I." in ${CFLAGS} here. bsd.kmod.mk now puts an absolute
path to the obj directory in ${CFLAGS}. This is actually equivalent
to "-I." since bsd.kmod.mk also puts -I- in ${CFLAGS}.

Make MOD_* macros almost consistent:

Use the name argument almost the same in all LKM types. Maintain
the current behavior for the external (e.g., modstat) name for DEV,
EXEC, and MISC types being #name ## "_mod" and SYCALL and VFS only
#name. This is a candidate for change and I vote just the name without
the "_mod".

Change the DISPATCH macro to MOD_DISPATCH for consistency with the
other macros.

Add an LKM_ANON #define to eliminate the magic -1 and associated
signed/unsigned warnings.

Add MOD_PRIVATE to support wcd.c's poking around in the lkm structure.

Change source in tree to use the new interface.

Revert $FreeBSD$ back to $Id$

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.

`struct linker_set execsw_set' was declared as const and pointers in it
were declared as non-const. This is backwards (_lkm_exec() changes the
pointers but all the target `struct execsw's are const). Fixed this
and poisoned related declarations to match and removed the bogus casts
that hid the bug.

Changed the first (name) arg of MOD_DEV(), MOD_EXEC() and MOD_MISC()
from a string to an identifier so that it can be used to generate
declarations and strings. It's much easier to stringize an identifier
than to identifize a string. A uniform naming scheme must be used
for the automatically generated things to apply. This is a feature.

Used the module identifer to generate prototypes for the module load,
unload and stat functions. Removed the few prototypes for these that
already existed.

Used the module identifier to generate a unique struct tag in MOD_DEV().
This should probably be done for all the MOD_*() macros.

Moved the trailing semicolon from the MOD_*() macro definitions to the
macro invocations that didn't already (bogusly) have it.

Staticized the module load and unload functions.

Added function return types for the module load, unload and stat functions.

lkm/ibcs2/ibcs2.c:
Included <sys/sysproto.h> to get everything prototyped.
Cleaned up #includes.

lkm/ibcs2/ipfw.c:
Cleaned up #includes.

lkm/linux/linux.c:
The module name had to change from "linux_emulator" to "linux_mod" to
be automatically generated.
Cleaned up #includes.

lkm/syscons/*/*_saver.c:
Completed delcarations of function pointers.

sys/i386/isa/atapi.c:
The module name had to change from "atapi" to "atapi_mod" to be
automatically generated.

sys/i386/isa/wcd.c:
Used the fixed MOD_DEV(). This module has two devices and expanded the
macro in the source instead of fixing it.
The module names had to change from "wcd" and "rwcd" to "wcd_mod" and
"rwcd_mod" to be automatically generated.

sys/pccard/pcic.c:
The module name had to change from "pcic" to "pcic_mod" to be
automatically generated.

Replaced nosys() by lkm_nullcmd(). Always call lkm load/unload/stat
functions instead of skipping the call if the function is nosys().
nosys() returned the wrong value as well as having the wrong type.

Do a pass over the broken LKM's and update them to use the "new"
convention of having their entry point named "<modname>_mod"".
Symorder is enforcing this when the current bsd.kmod.mk is installed.

I've not tested all these, but at least they all compile now.

Reattach them to the makefile.

Note that the change that I made to symorder needs to be compiled and
installed before any LKM's will work - the last version was corrupting
the relocation tables. A "make world" will to this, but if you
manually run a make on the lkm's you'll need to take care of it by
hand.

Remove trailing whitespace.

Again, this is not a filesystem so don't compile it as if it were.
