[*] You should not use this commit directly since this may wipe out data in
fields the user has changed. See future commit where this situation is
properly handled.
* src/client/Client (_init): Provide dapimap to DataApiMediator instance.
* src/client/dapi/DataApiMediator.js
(_dapi_map): New field.
(constructor): Accept dapimap. BC break (which is okay, since this is
still part of a topic branch). Assing to _dapi_map. Update docblock.
(monitor): Bind `dapi_manager' to first argument of handlers.
(_updateFieldData): Accept `dapi_manager' as first argument. Use
`_populateWithMap' to generate additional update data.
(_populateWithMap): New method.
(_clearFieldFailures): Accept `dapi_manager' as first argument.
* src/dapi/DataApiManager.js: Update copyright year.
(getDataExpansion): Return empty object (consistent with interface) rather
than `undefined' when field value is undefined. Use
{Error=>MissingDataError} when field data are missing. Throw instead of
emit. Fix missing comma in var declarations.
* src/dapi/MissingDataError.js: New class.
* test/client/dapi/DataApiMediatorTest.js: Update test data to test field
expansion. New test against ignoring field expansion when data are not
available. Update Sut constructors of other tests for new dapimap
parameter.
