* src/client/dapi/DataApiMediator.js (_populateWithMap): Update
docblock. Ignore field during expansion if it would overwrite an
existing value.
* test/client/dapi/DataApiMediatorTest.js: Update tests data to include
values for all bucket fields, not just `name'. Add test for new
condition.
DEV-3257
[*] 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.

This extracts existing code from Client and adds tests. The glue code is
far from ideal and highlights the amount of work needed to decouple Client
from so many parts of the system.
* src/client/Client.js (_dapiManager): New field.
(_init): Use DataApiMediator.
(_createProgram): Assign `_dapiManager' (this is not at all
ideal). Remove hooks from it: fieldLoading, updateFieldData,
clearFieldData.
* src/client/ClientDependencyFactory.js (createDataApiMediator): New alias
to DataApiMediator constructor.
* src/client/dapi/DataApiMediator.js: New class.
* test/client/dapi/DataApiMediatorTest.js: New test case.
