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.

d69f875261 - Set max-udp-size default to 1232. This is the same default value as
the default value for edns-buffer-size. It restricts client edns
  buffer size choices, and makes unbound behave similar to other DNS
  resolvers. The new choice, down from 4096 means it is harder to get
  large responses from Unbound. Thanks to Xiang Li, from NISL Lab,
  Tsinghua University.

0abfddd279 Allow using system certificates not only on Windows
OpenSSL has a way to load default file. That file might contain usable
certificates to verify common connections. Allow similar trust as on
windows and leave it on openssl package to provide sane defaults.

Also provide use-system-cert alias, because it is not windows specific
anymore.
