Don't start callouts for domains before attaching domains on rump kernels

On rump kernels, the callouts for domains, pffasttimo and pfslowtimo, started
before domains were attached. Normally the callouts were dispatched after
domain attaches (initializations) finished, however, under load the callouts
could be executed prior to the attaches, resulting in that the callouts accessed
unallocated or uninitialized resources.

Sweep unncessary radix.h inclusions

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.

Register netisr's from component constructors instead of via a hardcoded
global list.

branches: 1.16.2;
Remove routines which don't make sense (maybe they're some intermediate
phase of the component framework?)

Set networking soft interrupt vectors earlier, just in case interface
component initialization causes network traffic to be received.

Don't use __weak_alias where the component framework is sufficient.

Add one more component level to networking: IFCFG.
It is executed after IF and the purposes to guarantee the right
order in cross-component interface address configuration.

branches: 1.12.2;
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: 1.11.2;
Redefine bpf linkage through an always present op vector, i.e.
#if NBPFILTER is no longer required in the client. This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached. However, callers of bpf can
now be modularized.

Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff. ... and I'm not going to ponder the depths of unload
here.

Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

Initialize suckets before domains since some domains install timers
which take softnet_lock and might run before the lock is actually
initialized. Also, soinit() itself already calls soinit2(), so no
need to call it twice.

create interfaces only after ifnef is initialized

Use a bunch of weak symbols to determine which network components
are present. This works in userspace as opposed relying in link
sets, which fail miserably. Later, when the networking stack
becomes modularized, we can move to a dynamic scheme like with file
systems.

Also, this change allows us to do proper autoconfig, namely attach
the loopback interface iff it is present.
