Fix SIGSEGV in rfc1035.c answer_request() line 1228 where memset()
is called with header & limit pointing at the same address and thus
tries to clear memory from before the buffer begins.
answer_request() is called with an invalid edns packet size provided by
the client. Ensure the udp_size provided by the client is bounded by
512 and configured maximum as per RFC 6891 6.2.3 "Values lower than 512
MUST be treated as equal to 512"
The client that exposed the problem provided a payload udp size of 0.

Don't expose dnsmasq version & other data to clients via the *.bind
pseudo domain. This uses a new 'NO_ID' compile time option which has been
discussed and submitted upstream.
This is an alternate to replacing version with 'unknown' which affects
the version reported to syslog and 'dnsmasq --version'
Run time tested with & without NO_ID on Archer C7 v2

support as it turns out some clients are getting upset.

Bump to dnsmasq 2.77test1 - this includes a number of fixes since 2.76
and allows dropping of 2 LEDE carried patches.
Notable fix in rrfilter code when talking to Nominum's DNS servers
especially with DNSSEC.
A patch to switch dnsmasq back to 'soft fail' for SERVFAIL responses
from dns servers is also included. This mean dnsmasq tries all
configured servers before giving up.
A 'localise queries' enhancement has also been backported (it will
appear in test2/rc'n') this is especially important if using the
recently imported to LEDE 'use dnsmasq standalone' feature 9525743c
I have been following dnsmasq HEAD ever since 2.76 release.

This patch backports the option --tftp-no-fail to dnsmasq and prevents the
service from aborting if the specified TFTP root directory is not available;
this might be the case if TFTP files are located on external media that might
occasionally not be present at startup.

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.

This patch tries to
- Let the DHCPv6 feature depend on CONFIG_IPV6.
- Conditionally select libnettle, kmod-ipv6, kmod-ipt-ipset only if the
corresponding features are enabled.
- Install `trust-anchors.conf` only if DNSSEC is selected.
- Add PKG_CONFIG_DEPENDS for the configurable options.
- Add a patch to let the Makefile of dnsmasq be aware of changes in
COPTS variable.
Big thanks goes to Frank Schäfer <fschaefer.oss@googlemail.com> for
providing necessary information on connections and dependency relations
between these CONFIGs and packages.

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
and/or did not miss license information.

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.
