Previously, async routes generated from links would not load the configs of
their resolved components, which led to broken links in the children of the
async instruction's component.
This commit fixes the bookkeeping in the Router to correctly load the configs.
Fixes internal b/23791558
Closes#4146
This change moves many APIs to the angular2/core export.
This change also automatically adds FORM_BINDINGS in
the application root injector.
BREAKING CHANGE:
Many dependencies that were previously exported from specific
APIs are now exported from angular2/core. Affected exports, which
should now be included from angular2/core include:
angular2/forms
angular2/di
angular2/directives
angular2/change_detection
angular2/bootstrap (except for dart users)
angular2/render
angular2/metadata
angular2/debug
angular2/pipes
Closes#3977
