pagekite: prepare for modern OpenWrt packaging

Add maintainer, drop uci-defaults and add license information

Signed-off-by: Karl Palsson <karlp@tweak.net.au>
mosquitto: drop useless debug options

Used in some private testing, no purpose existing beyond that.
mosquitto: bump to 1.3.4

Remember: this repo only holds mosquitto if you need backfire/aa
support, future work is in openwrt itself, where we have commit access
now.
libwebsockets: Add latest release.

Based on version provided in libwebsockets repo, with minor adjustments.

Future plans are to optionize the ssl library to use.
libwebsockets: Only enable ipv6 if the build is ipv6 enabled

Makes sure it works on AA builds for instance.
mosquitto: bump to 1.4-development branch

This is an unreleased preview image. Optional support for libwebsockets
is included, default is enabled.
mosquitto: Skip building documentation by default
mosquitto: allow building on older trees

mosquitto > 1.3 (1.4 dev branches and later) have support for elliptic
curve encryption, but AA and older openwrt branches don't have an ssl
library supporting that.  Make sure that EC is disabled on older builds.
mosquitto: overhaul uci conversion script

Support more options coming with mosquitto 1.4
Use more built in functions to make script simpler and easier to extend
