default one is good enough.
So merge rc.conf(8)'s 'multicast_router' and 'multicast_host' into a
single 'multicast'.  If set to YES the reject route for 224/4 is not
inserted by netstart(8).

the b* byte functions belong in strings.h, not string.h so break
them out of string.h into a new strings.h.  As long as there is no
POSIX or X/OPEN define in use string.h will pull in strings.h.

This version of the function will always open the secure/shadow/master
password files. Soon, the regular variants of these functions will not.
(Intermixing shadow and regular gets a little weird; don't do that.)
Not using struct spwd and getspwnam functions to reduce churn in callers.

- Rename function to ifv6autoconf() to make IPv6 relation clearer
- Localize and rename variables
OK krw@

- Change comments to make it clearer that ifmstart() takes two lists
of interface driver names (of which the second is optional) and not
the actual interface instances.
- Use localized variables and use slightly more verbose names.
- Use continue 2 to skip to the next hostname.if file.
- Use shell pattern @() instead of testing _sif individually.
OK krw@

- Align comments with /etc/rc version
- Use localized variables
- Use safer "print -r --" instead of plain echo
Changes to ifstart():
- Tweak comment
- Add usage
OK krw@

thrkill(2), rolling the kill(2) syscall number with the ABI change to
avoid breaking binaries during during the transition.  thrkill(2) includes
a 'tcb' argument that eliminates the need for locking in pthread_kill()
and simplifies pthread_cancel().  Switch __stack_smash_handler() to use
thrkill(2) and explicitly unblock SIGABRT.
Minor bump to both libc and libpthread: make sure you install a new kernel!

stubs for the executable from crtbegin.o into libc, which lets them be
excluded from static links that don't use them.
For this, drop the normal crt{begin,end}S.o from libc.so: the .init and .fini
sections for libc aren't called at the right times anyway, so it's good that
they're unused.  libc.so just needs __guard_local and the .note.openbsd.ident
section, so add them to stack_protector.c for now (this will be improved)

creating the directory /usr/share/nls.  Having a non-existing default
path in catopen(3) does not make sense, so remove it.  If the user
does not specify a NLS path, better fail early than fail because
of an empty directory.  Remove path form hier(7).

General changes:
- apply a similar 'style' as used in the installer scripts
- improve comments to be more to the point, remove where code is obvious
- document usage of functions if they have arguments
- rename variables where it improves readability
- replace really old-school shell code with more contemporary idioms
Other changes:
- No need to care about "autoboot" because netstart doesn't inherit the
positional parameters from /etc/rc anymore. /etc/rc executes netstart
instead of sourcing it since r1.439.
- Use simpler for-loop to process list of interfaces with ifstart.
