Introduce a LWS_WITH_WOL and an api to wake a mac address, optionally with
an address bind to the local interface to go out on.
Add a helper to parse ascii mac addresses well, and add tests.

We use warmcat dns for testing, but for a while it has become dynamic
breaking the tests.
Fix up the affected tests with IPv4 addresses from getaddrinfo() so they
pass when they match these results.
Add some exports so the api test can inject results into the parser for
live queries, suppressing asking the server but otherwise following the
flow.
Provide two new suspect responses for injection and parsing in ctest.
Add a --cos option to minimal-http-client to force a close after the
connection has started the async dns.
