There are several definitions of the same functions manipulating timeval
structures. Let's move them to separate file and arrange the code
preperly.

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.

Create server cookies for clients that send client cookies.
Needs to be turned on in the config file with:
answer-cookie: yes
A cookie-secret can be configured for anycast setups.
Also adds an access control list that will allow queries with
either a valid cookie or over a stateful transport.
If there are only unsupported algorithms, or unsupported schemes,
and no failed or successful other ZONEMD records, or malformed
or bad ZONEMD records, the unsupported records allow the zone load.
