Don't expose dnsmasq version & other data to clients via the *.bind

This is an alternate to replacing version with 'unknown' which affects

Regression introduced by 3481d0d dnsmasq: run as dedicated UID/GID
dnsmasq is unable to remove its own pidfile as /var/run/dnsmasq is owned
by root and now dnsmasq runs as dnsmasq:dnsmasq. Change directory
ownership to match.
dnsmasq initially starts as root, creates the pidfile, then drops to
requested non-root user. Until this fix dnsmasq had insufficient
privilege to remove its own pidfile.

By default dnsmasq uses the time function; which returns the time since
Epoch; to retrieve the current time. On boards which have no realtime
clock this can lead to side effects when the time is synced via ntp
as the "time wrap" forces dhcp leases to be considered as expired.
By enabling the broken realtime clock build switch dnsmasq uses the
times utility which returns the number of clock tick.

Change dnsmasq's dnssec time check handling to use time validity
indicated by ntpd rather than maintaining a cross boot/upgrade
/etc/dnsmasq.time timestamp file. This saves flash device wear.
If ntpd client is configured in uci and you're using dnssec, then
dnsmasq will not check dnssec timestamp validity until ntpd hotplug
indicates sync via a stratum change. The ntpd hotplug leaves a status
flag file to indicate to dnsmasq.init that time is valid and that it
should now start in 'check dnssec timestamp valid' mode.
If ntpd client is not configured and you're using dnssec, then it is
presumed you're using an alternate time sync mechanism and that time is
correct, thus dnsmasq checks dnssec timestamps are valid from 1st start.

V2 - stratum & step ntp changes indicate time is valid
V3 - on initial flag file step signal dnsmasq with SIGHUP if running

result in unpleasant script race conditions

further testing
V6 - improve handling of non busybox ntpd

Add support for hostid dhcp config entry to dnsmasq. This allows

Changed option nonwildcard from --bind-interfaces into --bind-dynamic.
With this, Dnsmasq binds the address of individual interfaces, allowing multiple

listens on those. This makes dynamically created interfaces work in the same way as
the default, but allows also use of other DNS-servers (like Named) at the same time
on diffirent interfaces where Dnsmasq is NOT configured, whereas with
--bind-interfaces will still reserve every interface even if not used and thus
disallowing use of any other DNS-program even on unused interfaces.

Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.
I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.
However, I can not garantee that I always picked the correct information

An entry like this in /etc/config/dhcp:

option 'dns' '1'
results in a /tmp/hosts/dhcp entry that looks like this:

Obviously it should say "pc2.lan".
This happens because $name is set to "" in order to support the MAC-less

operations. Also, refuse to add a DNS entry if the hostname or IP is

DHCP entries in /etc/config/dhcp will not automatically create A or PTR
records. Add an "option dns" directive which appends an entry to
/tmp/hosts/dhcp to facilitate forward and reverse DNS lookups. For
instance, this item:
config host
option ip '192.168.0.10'
option mac '00:13:57:9b:df:02'
option name 'winpc'
option dns '1'
will add a corresponding entry to /tmp/hosts/dhcp:
192.168.0.10 winpc.lan
This keeps the hostname/IP/MAC in a single place, for easy maintenance.
Related: ticket #13854 reports an regression involving missing PTR
records when using "config domain" to define static DNS entries for
individual hosts. However, per Simon Kelley[1], the --address feature
used by "config domain" was never intended to generate DNS A records for
hosts. It would probably be better for the reporter to apply this patch,
and then use "config host" sections instead of "config domain" sections.
