Downstream projects might re-generate device-specific configuration
based on OpenWrt's defaults on each upgrade, thus being unaffected by
forward- as well as backwards-breaking configuration.
Add a new sysupgrade parameter, which allows sysupgrades between minor
compat-versions. Upgrades will still fail upon mismatching major compat
versions.

Verify image and config .tar.gz but do not actually flash.

Flash image even if image checks fail, this is dangerous!
+ --ignore-minor-compat-version
+ Flash image even if the minor compat version is incompatible.
