Put the kernelside rump kernel headers into <rump-sys> instead of
sprinkling them around the faction directories. Avoids having
to add a CPPFLAGS (or several) to pretty much every component
Makefile.

Leave compat headers around in the old locations.

The commit changes some autogenerated files, but I'll fix the
generators shortly and regen.

branches: 1.13.6;
use ioconf for mainbus

branches: 1.12.8; 1.12.18; 1.12.22;
Move FLAWLESSCALL from rump_dev_private.h into rump_private.h
so it can be used outside of devices.

define the incredible FLAWLESSCALL macro in one place

branches: 1.10.2;
Introduce RUMP_COMPONENT. It behaves mostly like a simplified
module which is linked into the kernel and cannot be unloaded.
The main purpose is to get the proper constructors run and create
any /dev nodes necessary for said component. Once more of the
kernel (e.g. networking stack and device drivers) are converted to
MODULE and devfs pops up from somewhere, rump components can be
retired.

branches: 1.9.2;
Add sysmon rump component.

Add bpf rump component (and put in some wscons stuff i forgot to earlier).

Add initial version of RUMP based device-mapper port. libdm compile whole
device-mapper driver in userspace and allows us to test a develop new dm targets
in userspace.

pass unit number in mainbus attach args

add a new init-related calls

initialize rnd if present

Rename rump_dev_makenodes() to rump_vfs_makedevnodes() -- while it
will most likely be used devices, the implementation requires
services provided by vfs (mkdir, mknod).

add netsmb rump component
(yes, it's functionally a device instead of a networking domain,
since it provides and is accessed through /dev/nsmb instead of
being accessed through sockets)

branches: 1.1.2; 1.1.4;
device subroutines and autoconfig support for rump. work in progress.
