Minor and non-functional enhancements in mount_portal(8)

Since day0 pt_exec.c shipped with a dummy stub for "exec" operation, stop
waiting longer and eliminate it now. This functionality can be achieved
with filters.

Drop FreeBSD CVS repos references. There are certainly still some mirrors
or old mirrors available, but since the project moved to SVN+GIT entirely
drop it.

Add CVS Id - where missing - to the documentation files. This helps users
to determine how recent are the files.

Define _KERNTYPES for things that need it.

document non-literal strings

Remove the portalfs kernel file system driver. Replace mount_portal(8)
with a version based on puffs. User functionality remains the same.

Move WARNS=3 to the Makefile.inc, and add a little const to the remaining
programs that did not compile before.

Kill __P(), use ANSI function declarations, constify; WARNS=3.

unifdef -DINET6. getaddrinfo will always be there, so there's no point in
keeping old code. moreover old code does not traverse list of DNS-returned
addresses.

move getmntopts(3) to libutil, build and install also it's manpage
bump libutil minor
adjust individual mount_*/Makefile to use libutil getmntopts(3)

Use ${NETBSDSRCDIR}/some/path instead of ${.CURDIR}/../../some/path

support IPv6. PR 11858 from ura@hiru.aoba.yokohama.jp

convert to use regex (it used compat regexp previously), g/c now unneded stuff

Initial support for rfilter and wfilter namespaces, in pt_filter.c.
Also, recur into ./examples, to grab the tutorial and example configurations.

We use regexp(3), better link w/ libcompat!

Remove -lcompat; not needed.

CFLAGS->CPPFLAGS

Back out the .PATH.c changes. The .depend problem (and others)
will be fixed using the new .NOPATH make feature instead.

Use .PATH.c: ...

convert to new RCS Id conventions; reduce my headache

specify man pages the new way.

do not need -I/sys

X compilation

Update from 4.4-Lite, with local changes.

don't need -lutil

Remove some notdefage and link with libutil so we properly daemonize.

it uses the old regex stuff, so include -lcompat

Get CFLAGS right so the blasted thing is optimized.
