Sending via broadcast/multicast is now supported for both
IPv4 and IPv6 and the configuration syntax made
easier (but backwards compatible).

Fix error created in 1ce1c6beae9f683bec54cba4c0d375f85b209b95

Many thanks to Hartmut Birr for finding the bug and bisecting to
the guilty commit.

The breaking commit creates cache entries which have F_NXDOMAIN
set but none of F_IPV4, F_IPV6 or F_SRV. If cache_scan_free() is called
to delete such an entry it will fail to do so.

If the cache has no free slots and the least-recently-used slot is such
an entry, then a new insertion will attempt to make space by calling
cache_scan_free(), which will fail when it should be impossible and
trigger the internal error.

To be treated as hex, the pattern must consist of only hex digits AND
contain at least one ':'. Thanks to Bengt-Erik Sandstrom who tripped
over a pattern consisting of a decimal number which was interpreted
surprisingly.

…nsmasq does the same but config-aware, i.e. it will not complain about missing CAP_NET_ADMIN when DHCP is not used. As its warnings are now much more present in all logs, we don't need to do the check twice. The existing checks remain there but are only used in debug mode (DEBUG_CAPS).

If dnsmasq re-reads a resolv file, and it's empty, it will
retry after a delay. In the meantime, the old servers from the
resolv file have been deleted, but the servers_array doesn't
get updated, leading to dangling pointers and crashes.

Thanks to Brad Jorsch for finding and analysing this bug.

This problem was introduced in 2.86.

The 2.86 upstream server rewrite severely broke re-reading
of server configuration. It would get everyting right the first
time, but on re-reading /etc/resolv.conf or --servers-file
or setting things with DBUS, the results were just wrong.

This should put things right again.
