Add support for configuring the base storage URL for Flutter's
artifacts. If FLUTTER_STORAGE_BASE_URL is set, use it instead of
storage.googleapis.com.
The pub server can be overridden by setting PUB_HOSTED_URL.

Adds a class `PubContext` with a fixed set of allowed values
Make it clear these values should not be changed casually
Fixed one inconsistency already: update_packages vs update_pkgs
Provide more information for verify calls
Eliminate `ctx_` prefix.
This adjusts the CupertinoTabBar height in the presence of bottom
padding. On the iPhone X, this will increase the height to account for
the home indicator widget.
The purpose of this PR is to make it so that when the user runs 'flutter', if they have a .pub-cache directory in their flutter root, we use that instead of the default location for the pub cache. Otherwise, it should act as before.
The eventual goal is to support a pre-populated flutter .zip/.tar.gz file that has everything the developer needs in one bundle. In order for that to actually work, we need to have the pub cache be self-contained, and not in the user's home dir.
Another advantage of this is that if you have multiple flutter repos that you're switching between, then the versions in the pub cache will remain static when you switch between them.
This is an attempt to re-land: #13248. Includes a fix for the test that makes it work on bots in the presence of PUB_CACHE being set, and no other changes.
* Revert "Add tests."
This reverts commit 31bad961ff2220a2708917ff8f748fed7efa9b51.
* Revert "Use .pub-cache from Flutter root, if it exists. (#13248)"
This reverts commit 72d6bcc3f7555c5a242f46cb09484f6c12e86f39.
It turns out that when a PR build clones the flutter repo, it puts it into a directory called "flutter", and when the "real" build clones the flutter repo, it puts it into a directory called "build". This allowed the tests to succeed in my PR, but fail when I committed it.
This fixes the test so it doesn't depend on the cloned directory name.

Summary:
- Add `key` field to `SemanticsNode`, while moving key into `foundation` library so it can be used by the render layer.
- Introduce `SemanticsProperties` and move many of the `Semantics` fields into it.
- Introduce `CustomPaintSemantics` - a `SemanticsNode` prototype created by `CustomPainter`.
- Introduce `semanticsBuilder` and `shouldRebuildSemantics` in `CustomerPainter`
**Breaking change**
The default `Semantics` constructor becomes non-const (due to https://github.com/dart-lang/sdk/issues/20962). However, a new `const Semantics.fromProperties` is added that still allowed creating constant `Semantics` widgets ([mailing list announcement](https://groups.google.com/forum/#!topic/flutter-dev/KQXBl2_1sws)).

Separate focus management by build owner
Currently the focus manager is held by the singleton WidgetBinding.
This change places a focus manager in each build owner object,
which allows clients to run offscreen pipelines without disturbing
focus management for the main UI.
