We migrate to dnsmasq-full, while disabling most of its features.
Notably, dhcp and dnssec are compiled in, while other features of the
full variant are deselected.
This removes PKG_VERSION and PKG_RELEASE from most Makefiles, as the
value was never useful for Gluon packages; instead, PKG_VERSION is set
to 1 in gluon.mk.
It also removes two other weird definitions:
- gluon-iptables-clamp-mss-to-pmtu replicating the old PKG_VERSION logic
from gluon-core, but without the fixed PKG_BUILD_DIR to prevent
unnessary rebuilds
- gluon-hoodselector set GLUON_VERSION=3
Specify conffiles for our packages, so they aren't overwritten during
opkg updates. While this only matters during development, it is
unintended to have different behaviour for opkg update and full firmware
updates.
This commit changes the behavior for the wan-dnsmasq to read the
interfaces to update the DNS servers on from flag-files.
This way, external custom packages which add a custom VPN WAN interface
can update the DNS server gluon is using for WAN resolving.
