enhance ContextBuilder getAnalysisOptions to handle lints

enhance ContextBuilder getAnalysisOptions to handle lints

This updates ContextBuilder to process the --lints command line option:
* --[no-]lints enables (or disables) lints
* if --lints but no lints specified in analysis options
    then the default set of lints is used
* if --no-lints then lints are turned off
    regardless of what is specified in the analysis options
* if neither --lints nor --no-lints are specified
    then lints are turned on iff analysis options specifies lints

My next step is to update analyzer_cli to use ContextBuilder getAnalysisOptions
