Subject: cam: options: Add public method to invalidate options
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extend OptionsBase<T> with a public invalidate() method. This allows for
further examination of the options and if found unsuitable be
invalidated. The intended user for this new interface are subclasses of
KeyValueParser.
