* Fix container instantiation timing, IID startup.
The container instantiation could happen at the wrong time, before all
components have been added to the container. This fixes it, and also
moves IID to use the proper instantiation timing instead of relying on
the `configureWithApp:` call. This is part continuation of #3147, where
I'll be fixing the rest of the SDKs in follow up PRs.
* Typo
* Further work on instantiation timing.
This moves the instantiation of components to after the FirebaseApp is
completely configured and assigned, as it should be. This also exposed
a recursive issue with IID calling the Messaging singleton, which in
turn called IID and instantiated multiple instances.
A change was made to break the cycle: the Messaging `isAutoInitEnabled`
call was changed to a static method vs an instance method, allowing IID
to call it during initialization without instantiating the Messaging
instance (since it doesn't have a direct dependency on it).
* Revert unintentional formatting of entire FIRMessaging file.
* Fix tests.
* Format InstanceID.m
* Remove unused import.
* Fix ComponentContainer test.
* Minor PR feedback.
* Add versioning to Functions and convert to FIRLibrary
* Convert Firestore to FIRLibrary
* Point travis to FirebaseCore pre-release for its deps
* Update user agent strings to match spec
* Add FirebaseCore component interoperability.
This puts in place the system that will allow SDKs to register with
Core and retrieve functionalities provided by other SDKs.
* Updated documentation.
* Add copywrite, fix log messages.
* Explicitly import headers from Private dir
