Use 2001:db8::/32, the official IPv6 subnet for
configuration examples.
This makes the IPv6 example consistent with IPv4, and removes a dubious
mention of a 6bone subnet.

Fix bug introduced in rev 1.467 which causes
"buffer_get_bignum_ret: incomplete message" errors when built with WITH_SSH1
and run such that no Protocol 1 ephemeral host key is generated (eg "Protocol
2", no SSH1 host key supplied). Reported by rainer.laatsch at t-online.de,

NetBSD added an strnvis and unfortunately made it incompatible with the
existing one in OpenBSD and Linux's libbsd (the former having existed
for over ten years). Despite this incompatibility being reported during
development (see http://gnats.netbsd.org/44977) they still shipped it.
Even more unfortunately FreeBSD and later MacOS picked up this incompatible
implementation. Try to detect this mess, and assume the only safe option
if we're cross compiling.
OpenBSD 2.9 (2001): strnvis(char *dst, const char *src, size_t dlen, int flag);
NetBSD 6.0 (2012): strnvis(char *dst, size_t dlen, const char *src, int flag);

If the root account is locked (eg password "!!" or "*LK*") keep looking

invalid users. ok djm@
Since adding $(REGRESSLIBS), $? is wrong because it includes only the
changed source files. $< seems like it'd be right however it doesn't
seem to work on some non-GNU makes, so do what works everywhere.
Add some unsigned overflow checks for extra_pad. None of
these are reachable with the amount of padding that we use internally.

bz#2249: handle the case where PAM returns PAM_MAXTRIES by ceasing to offer
password and keyboard-interative authentication methods. Should prevent
"sshd ignoring max retries" warnings in the log. ok djm@
It probably won't trigger with keyboard-interactive in the default
configuration because the retry counter is stored in module-private
storage which goes away with the sshd PAM process (see bz#688). On the
other hand, those cases probably won't log a warning either.

Some AIX compilers unconditionally undefine va_copy but don't set it back
to an internal function, causing link errors. In some compat code we
already use VA_COPY instead so move the two existing instances into the
shared header and use for sshbuf-getput-basic.c too. Should fix building
with at lease some versions of AIX's compiler. bz#2589, ok djm@
