648ad4db6f Linting change.
Remove config parser/lexer code as it's rebuilded every time but can
break adding new config options.
Also clean up the code base to avoid mixing actual code changes and lint
issues.

d4314cad33 Make VAL_MAX_RESTART_COUNT configurable.
unbound tries very hard (up to 6 authoritative servers) to find a
validating answer. This is not always desirable, for example on high
latency links.
