Some of the puffs mount programs don't need RUMP, re-enable them.

If compiled with RUMP_ACTION, access rump kernel instead of host
kernel. This is an easy way to browse & modify the sysctl tree
offered by a rump kernel instance.

Enable WARNS=4 by default, except for:
cpuctl dumplfs hprop ipf iprop-log kadmin kcm kdc kdigest
kimpersonate kstash ktutil makefs ndbootd ntp pppd quot
racoon racoonctl rtadvd sntp sup tcpdchk tcpdmatch tcpdump
traceroute traceroute6 user veriexecgen wsmoused zic
(Mostly third-party applications)

add mount_sysctlfs.8

move sysctlfs from examples to base

Sort options in SYNOPSIS (flags without arguments first).

Add raw mode, which skips ASCII'ification and can be used if reading
structures from the kernel into debug program memory is desired.

add mount_sysctlfs.8

add a space between the closing bracket and else keyword.

add missing '\n'

nothing is executable.

- protect against node not found SEGV
- fix reversed logic; if we find it in the cache we return it, otherwise
we create it.

branches: 1.18.2;
Add usage function, various cosmetics; no functional change.

add the headers you need

support CTLTYPE_BOOL

If compiled with RUMP_ACTION, access rump kernel instead of host
kernel. This is an easy way to browse & modify the sysctl tree
offered by a rump kernel instance.

Add raw mode, which skips ASCII'ification and can be used if reading
structures from the kernel into debug program memory is desired.

Instead of totally giving up, dump CTLTYPE_STRUCT as hex, much
like sysctl -x (but not fancy like -dosequis).

more lp64 it's-a-sign! fixes

Fix a crash while trying to read nodes on amd64, reported in PR/41494,
by not doing any transfert when offset exceed the actual data length.

From and ok by pooka@.

fix -Wsign-compare issues

Rototill.

Ok, ok, a few more words about it: stop holding puffs_cc as a holy
value and passing it around to almost every possible place (popquiz:
which kernel variable does this remind you of?). Instead, pass
the natural choice, puffs_usermount, and fetch puffs_cc via
puffs_cc_getcc() only in routines which actually need it. This
not only simplifies code, but (thanks to the introduction of
puffs_cc_getcc()) enables constructs which weren't previously sanely
possible, say layering as a curious example.

There's still a little to do on this front, but this was the major
fs interface blast.

Remove "puffs_cid" from the puffs interface following l-removal
from the kernel vfs interfaces. puffs_cc_getcaller(pcc) can be
used now should the same information be desired.

use puffs_daemon() instead of daemon()

Actually, daemonize the file servers before mounting. I might require
at some point that the local protocol handler does not change after
the file system has been mounted.

Pull the daemonizing code out of the library mainloop into the file
servers. Calling daemon() (i.e. fork()ing) inside a library can
cause nice surprises for e.g. threaded programs. As discussed with
Greg Oster & others.
