Log Message:
First part of secmodel cleanup and other misc. changes:

  - Separate the suser part of the bsd44 secmodel into its own secmodel
    and directory, pending even more cleanups. For revision history
    purposes, the original location of the files was

        src/sys/secmodel/bsd44/secmodel_bsd44_suser.c
        src/sys/secmodel/bsd44/suser.h

  - Add a man-page for secmodel_suser(9) and update the one for
    secmodel_bsd44(9).

  - Add a "secmodel" module class and use it. Userland program and
    documentation updated.

  - Manage secmodel count (nsecmodels) through the module framework.
    This eliminates the need for secmodel_{,de}register() calls in
    secmodel code.

  - Prepare for secmodel modularization by adding relevant module bits.
    The secmodels don't allow auto unload. The bsd44 secmodel depends
    on the suser and securelevel secmodels. The overlay secmodel depends
    on the bsd44 secmodel. As the module class is only cosmetic, and to
    prevent ambiguity, the bsd44 and overlay secmodels are prefixed with
    "secmodel_".

  - Adapt the overlay secmodel to recent changes (mainly vnode scope).

  - Stop using link-sets for the sysctl node(s) creation.

  - Keep sysctl variables under nodes of their relevant secmodels. In
    other words, don't create duplicates for the suser/securelevel
    secmodels under the bsd44 secmodel, as the latter is merely used
    for "grouping".

  - For the suser and securelevel secmodels, "advertise presence" in
    relevant sysctl nodes (sysctl.security.models.{suser,securelevel}).

  - Get rid of the LKM preprocessor stuff.

  - As secmodels are now modules, there's no need for an explicit call
    to secmodel_start(); it's handled by the module framework. That
    said, the module framework was adjusted to properly load secmodels
    early during system startup.

  - Adapt rump to changes: Instead of using empty stubs for securelevel,
    simply use the suser secmodel. Also replace secmodel_start() with a
    call to secmodel_suser_start().

  - 5.99.20.

Testing was done on i386 ("release" build). Spearated module_init()
changes were tested on sparc and sparc64 as well by martin@ (thanks!).
