afadc531af missed cvs add in previous commit: 
Define MODULAR for rump core components.  This enables module
loading via the kernel module framework (instead of dlopen()).
For now it only works on amd64 and i386, but for the rest it should
just be a matter of including the relevant kobj_machdep.c modules
from the kernel sources.

f8829b7dcb Switch i386 away from rump/include/machine. This means that rump 
on i386 now uses the native kernel ABI.  This in turn means that
rump modules and kernel modules are binary equivalent and can be

9c68331911 Store config(1)'s root filesystem type as a text string rather than 
embedding the address of its xxx_mountroot() in swapnetbsd.c.  This
permits booting of kernels with hard-wired filesystem type even if the
filesystem is in a loadable module (ie, not linked into the kernel
image).

Discussed on current-users.  Tested on amd64 and i386 with both hard-
wired and '?' filesystem times, and on both modular and monolithic
kernels.

Thanks to pooka@ for code review and suggestions.

8a7a4b8184 Add a simple example of how to use rump networking facilities. 
This just contacts www.NetBSD.org, does GET / and displays the
result.

It either uses the host kernel socket provided PF_INET or the kernel
TCP/IP stack running in userspace (via if_virt and /dev/tap),
depending on the libraries it's linked with.

b33ee0fb5c Support callouts and call callout_hardclock() from the timer 
interrupt thread.

The sleepq implementation required for callouts is horrible, kludged
only for callouts, and generally unacceptable.  It needs revisiting,
but I'm not sure yet should rump or kern_timeout be improved.  It's
almost untested as of now, but committing this will give me some
maneuvering space while letting application compile.

f88be1435b Rewrite interrupts to provide better softintr support, i.e. not 
execute them simply in the context of the scheduling code, as this
does not work for all applications (e.g. networking soft interrupts).
Rather, schedule them and execute them from a separate context.

Also provide a timer which for now executes just hardclock_callout()
(well, at least after callouts are included in librump, which is
soon).

61e869be3c Implement a virtual userspace networking interface. This is required 
for any sensible operation when running the entire TCP/IP stack in
userspace (as opposed to libsockin which uses host kernel networking
to provide PF_INET).

While this basically works (although it is quite barebones), it
depends on some bit of cleanup in librump and is not built by
default yet.

ad9bbd7b26 Add a very simplistic PF_INET/SOCK_DGRAM domain/proto implementation, 
which delegates the work to host kernel sockets.  This does not
run the entire kernel TCP/IP stack in userspace and therefore does
not require the ability to send or receive raw packets.  This
implies that root priviledges are not required.  As already said
above, only supports UDPv4 for now.  Extending should be easy.

827e91dd6f Make syspuffs mount code supply mount_syspuffs_parseargs() like 
the other mount binaries do.  Now syspuffs can be used to run all
puffs file systems as utilities.  This includes fuse file systems
and becomes interesting with the fs-utils project.  We can now do
e.g. this:

  ReFUSE ntfs-3g:
golem> echo hello | fsu_write/fsu_write ntfs-3g puffs ~/img/ntfs.img dafile
golem> fsu_cat/fsu_cat ntfs-3g puffs ~/img/ntfs.img dafile
hello
golem>

  puffs sysctlfs:
golem> fsu_ls/fsu_ls mount_sysctlfs puffs sysctl -l ddb

Same works for psshfs etcetc.

In other words, this provides total integration for "normal"
in-kernel file systems and puffs/fuse file systems on the ukfs
library level.

Note: implementation is still "first stab" and the fs-utils usage
will no doubt change.
