A set of tags can be specified for --dhcp-host option to restrict the
assignment to the requests which match all the tags.

Example usage:

config vendorclass
        option networkid 'udhcp'
        option vendorclass 'udhcp'

config host
        option mac '*:*:*:*:*:*'
        list match_tag 'switch.10'

ba5bd8e556 dnsmasq: distinct Ubus names for multiple instances
Currently, when using multiple dnsmasq instances they are all assigned
to the same Ubus instance name. This does not work, as only a single
instance can register with Ubus at a time. In the log, this leads to
`Cannot add object to UBus: Invalid argument` error messages.
Furthermore, upstream 3c93e8eb41952a9c91699386132d6fe83050e9be changes
behaviour so that instead of the log, dnsmasq exits at start instead.

With this patch, all dnsmasq instances are assigned unique names so that
they can register with Ubus concurrently. One of the enabled instances
is always assigned the previous default name "dnsmasq" to avoid breaking
backwards compatibility with other software relying on that default.
Previously, a random instance got assigned that name (while the others
produced error logs). Now, the first unnamed dnsmasq config section is
assigned the default name. If there are no unnamed dnsmasq sections the
first encountered named dnsmasq config section is assigned instead.

A similar issue exists for Dbus and was similarly addressed.

acb336235c dnsmasq: 'ipset' config sections
Allow configuring ipsets with dedicated config sections:

    config ipset
        list name 'ss_rules_dst_forward'
        list name 'ss_rules6_dst_forward'
        list domain 't.me'
        list domain 'telegram.org'

instead of current, rather inconvenient syntax:

    config dnsmasq
        ...
        list ipset '/t.me/telegram.org/ss_rules_dst_forward,ss_rules6_dst_forward'

Current syntax will still continue to work though.

With this change, a LuCI GUI for DNS ipsets should be easy to implement.

d20007ce91 dnsmasq: support tftp_unique_root in /etc/config/dhcp
The TFTP server provided by dnsmasq supports serving a select boot image
based on the client's MAC or IP address. This allows an administrator
to activate this feature in /etc/config/dhcp. Here is an example
/etc/config/dhcp that configures dnsmasq with --tftp-unique-root=mac:

...

config dnsmasq
	option enable_tftp 1
	option tftp_root /usr/libexec/tftpboot
	option tftp_unique_root mac

config boot router
	option serveraddress 192.168.1.1
	option servername tftp.example.com
	option filename openwrt-initramfs-kernel.bin

...

With this configuration, dnsmasq will serve
/usr/libexec/tftpboot/00-11-22-33-44-55/openwrt-initramfs-kernel.bin to
the client with MAC address 00:11:22:33:44:55.

064dc1e81b dnsmasq: abort when dnssec requested but not available
Before this commit, if uci option "dnssec" was set, we pass "--dnssec"
and friends to dnsmasq, let it start and decide whether to quit and
whether to emit message for diagnosis

  # dnsmasq --dnssec; echo $?
  dnsmasq: DNSSEC not available: set HAVE_DNSSEC in src/config.h
  1

DNSSEC as a feature is different from others like dhcp, tftp in that
it's a security feature.  Better be explicit.  With this change
committed, we make it so by not allowing it in the first in the
initscript, should dnsmasq later decides to not quit (not likely) or
quit without above explicit error (unlikely but less so ;)

So this is just being proactive.  on/off choices with uci option
"dnssec" are still available like before

b17a5a9bdb dnsmasq: always inform about disabled dhcp service
Init script checks for an already active DHCP server on the interface
and if such DHCP server is found, then it logs "refusing to start DHCP"
message, starts dnsmasq without DHCP service unless `option force 1` is
set and caches the DHCP server check result.

Each consecutive service start then uses this cached DHCP server check
result, but doesn't provide log feedback about disabled DHCP service
anymore.

So this patch ensures, that the log message about disabled DHCP service
on particular interface is always provided.

556b8581a1 dnsmasq: fix dnssec+ntp chicken-and-egg workaround (FS#2574)
Fix the test for an enabled sysntp initscript in dnsmasq.init, and get
rid of "test -o" while at it.

Issue reproduced on openwrt-19.07 with the help of pool.ntp.br and an
RTC-less ath79 router.  dnssec-no-timecheck would be clearly missing
from /var/etc/dnsmasq.conf.* while the router was still a few days in
the past due to non-working DNSSEC + DNS-based NTP server config.

The fix was tested with the router in the "DNSSEC broken state": it
properly started dnsmasq in dnssec-no-timecheck mode, and eventually ntp
was able to resolve the server name to an IP address, and set the system
time.  DNSSEC was then enabled by SIGINT through the ntp hotplug hook,
as expected.

A missing system.ntp.enabled UCI node is required for the bug to show
up.  The reasons for why it would be missing in the first place were not
investigated.
