Switch to std kern_auth.

Move global malloc types from kern_malloc into a separate module.

Make it possible to control starting of threads per env variable
instead of only at compile-time.

Add support for using real kmem/vmem. Don't enable it by default,
though, since it a) is a lot of unnecessary indirection in rump
b) requires callouts which are so far unimplemented.

Install rump libraries and utilities to the base system and remove the
private non-installed build infrastructure from sys/rump.

Install rump libraries and utilities to the base system and remove the
private non-installed build infrastructure from sys/rump.

breakdown of commit:
* install relevant headers into /usr/include/rump
* build sys/rump/librump/rumpuser and sys/rump/librump/rumpkern
from src/lib and install as librumpuser and librump, respectively
+ this retains the ability to test a librump build with just the
kernel sources at hand
* move sys/rump/fs/lib/libukfs and sys/rump/fs/lib/libp2k to src/lib
for general consumption, they are not kernel-space dwellers anyway
* build and install sys/rump/fs/lib/lib$fs as librumpfs_$fs
* add chapter 3 manual pages for rump, rumpuser, ukfs and p2k
* build and install userspace kernel file system daemons if MKPUFFS=yes
is spexified
* retire fsconsole for now, it will make a comeback with an actually
implemented version shortly

Repeat after me: do not pollute sys with #ifdef _RUMPKERNEL

emulate vlog()

Don't compile kern_lock for rump any more, it's no longer required.
Allows us to get rid of the incorrect _RUMPKERNEL ifdefs outside sys/rump.

Make kpause() use nanosleep() instead of usleep(). Fixes >=1s sleeps
to actually sleep a bit too.

Also fake the namecache g/c thread in kthread_create() so that file
systems can again be run without threads (and hence gdb can be used
on them).

Support multiple file systems within one process with ukfs by using

Implement yield().

Add dummy hardclock_ticks.

Use vfs_subr.c from sys/kern. This brings differences in the vnode
life cycle between rump and a real kernel to a minimum.

Use namei() etc. from kernel sources instead of a reimplementation.
To accommodate, give the rootvnode its own vnode op vector with a
simple lookup operation. This is used for looking up the file
system's device vnode instead of doing that directly in a homesmoked
namei().

Don't use PAGE_SIZE when faking physmem, as it's not always available
at compile-time. We could init it runtime, but it's just a random
number anyway.
