This drops patch that is backport of uClibc fix from upstream. We
already have that in our new version.

This is incompatible with 4.14 so we revert it. This allows us to still
have same package but just with this small change.

Mozilla decided to remove packages from OpenWrt 19.07 and master

This reverts commit 32ed9304.

Badly rebased

This reverts commit that drops our own version of ruby and replaces it
with upstream one instead. It introduces separate packages for
breakpoints and compass.
We do not want to do such big change in 4.0 any more so instead this is
being reverted here. We should drop this patch with 4.1.

Upstream changed names of variables in /etc/os-release to correspond to
correct project name. It is no longer Lede but once again OpenWRT.

Configuration override options was misleading. In reality those are
options you most probably don't want to mess too much with so let's call
them rather advanced options.

This also moves PUBLISH_BRANCH in example configuration file to
section: don't mess with. This is because now we provide it from
defaults and user just should not mess with it unless he know what he is
doing.

OpenWRT commit to be used is specified in feeds.conf file with rest of
feeds now so it makes not sense to overwrite it. This is just confusing
without any real gain in here. You can always modify feeds.conf file to
achieve the same.
