The `*_label' fields were not being properly set because they were being
considered just as every other expanded field, which is subject to other
considerations to ensure that we do not overwrite user data. Label fields,
on the other hand, _must_ always be set whenever the value changes, and are
_not_ modifiable by the user.
This codifies that `_label' assumption that I would like removed in the
future, but time does not permit that sort of refactoring right
now. Ideally, labels would be treated generically like any other expanded
field and have an attribute set of them that would change their expansion
behavior.
* src/client/dapi/DataApiMediator.js (_updateFieldData): Pass label field id
to `_populateWithMap'.
(_populateWithMap): Use it to always populate the label field when the key
matches, ignoring the other expansion criteria that would inhibit it.
* test/client/dapi/DataApiMediatorTest.js: Update test accordingly.
* src/dapi/DataApiManager.js (triggerFieldUpdate): Provide id to
`_genUiFieldData'.
(_genUiFieldData)[label_id]: New field. Return it as part of the return
object's `label_id' field.

Allowing the stack to clear ensures that (in practice) DelayedStagingBucket
is given a chance to do necessary processing before data are requested from
it by bucket hooks as a result of _this_ invocation, which in turn
results (in some cases) in infinite recursion.
* src/client/dapi/DataApiMediator.js (_updateFieldData): Allow stack to
clear before invoking `quote.setData'.
* test/client/dapi/DataApiMediatorTest.js: Test respectively.
DEV-3257
* 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.

[*] 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.
