conditionally save dnsmasq.time across sysupgrade
dnsmasq uses /etc/dnsmasq.time as record of the last known good
system time to aid its validation of dnssec timestamps. dnsmasq
updates the timestamp on process start/stop once it considers the system
time as valid. The timestamp file should be preserved across system
upgrade but should not be included as part of normal configuration
backups to prevent restores corrupting the current timestamp.

Running dnsmasq in a dedicated user/group allows matching its outgoing
traffic more easily using iptables' owner match.
Add UID/GID to the package metadata and append the user/group
parameters to the init script.

Enable setting a host-specific lease time for static hosts.
The new option is called "leasetime" and the format is similar
as for the default lease time: e.g. 12h, 3d, infinite
Default lease time is used for all hosts for which there is
no host-specific definition.
The option is added to /etc/config/dhcp for the selected hosts:
config host
option name 'Nexus'
option mac 'd8:50:66:55:59:7c'
option ip '192.168.1.245'
option leasetime '2h'
It gets appended to /var/etc/dnsmasq.conf like this:
dhcp-host=d8:50:66:55:59:7c,192.168.1.245,Nexus,2h

Commit 6a7e56b adds support for adding local hostname for own lan ula adress
but if ula prefix is not specified results into an invalid config (address=/OpenWrt.lan/1)
causing dnsmasq not to start up.
Use lanaddr6 when adding local hostname as the lan ula address is constructed based on the
UCI parameters ip6hint and ip6ifaceid and thus not always ula prefix suffixed with 1

Changed option nonwildcard from --bind-interfaces into --bind-dynamic.
With this, Dnsmasq binds the address of individual interfaces, allowing multiple
dnsmasq instances, but if new interfaces or addresses appear, it automatically
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.

DNSMASQ has the ability to provide a menu to a pxeboot system, using
the --pxe-prompt and --pxe-service configuration options. The current
init.d script converting the "dhcp" file to "dnsmasq.conf" does not
find these options, but they are supported. This patch thus enables
the options.

An entry like this in /etc/config/dhcp:
config 'host'
option 'name' 'pc2'
option 'ip' '192.168.100.56'
option 'dns' '1'
results in a /tmp/hosts/dhcp entry that looks like this:
192.168.100.56 .lan
Obviously it should say "pc2.lan".
This happens because $name is set to "" in order to support the MAC-less
syntax: "--dhcp-host=lap,192.168.0.199". Fix this by reordering the
operations. Also, refuse to add a DNS entry if the hostname or IP is
missing.

LuCI creates "domain" UCI config sections, which the dnsmasq init file
then, currently, translates into "address" config lines. This is not
the correct usage of "address" (see r36943), and also causes rDNS
records to not be created. This patches dnsmasq.init to utilize the
additional hosts file introduced in r40799 for such domain names,
resolving both issues.

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.

Changeset r36943 ("dnsmasq: use host-record instead of address") removed
the automatic domain expansion for config domain sections, this breaks
existing setups and alters the old behaviour in unexpected ways, therfore
restore behaviour of the current stable release.
Additionally handle fully qualified hostnames properly when setting up the
own hostrecord by stripping the local domain part form the given name
instead of unconditionally appending it, so that "example.lan" results
in "example example.lan" and not "example.lan example.lan.lan".

There are certain consumer devices which are outliers in protocol conformance.
An example is Samsung bluray players, which require broadcast DHCP responses
