And, allow for roughly a years worth of entries in dateMap and requestMap before
re-hashing by setting initial capacity.  Defaults are fine for the small ipMap
and protocolMap.

Use 'putIfAbsent'.

2018-02-05T17:06:23+00:00

Provide 'equals' and 'hashCode' implementations.

Reduce memory footprint of log lines.

Also make validation optional for internal web log constructor.
CollecTor uses this for storing freshly sanitized logs,
which don't need to be validated a second time.

Use enum for request method.
