This requires delicate handling of type definitions which collide, because
we use TypeScript-provided lib.d.ts for --target=es5 and lib.es6.d.ts for
--target=es6.
We need to include our polyfill typings only in the --target=es5 case,
and the usages have to be consistent with lib.es6.d.ts.
Also starting with this change we now typecheck additional modules,
so this fixes a bunch of wrong typings which were never checked before.
Fixes#3178
BREAKING CHANGE:
Replace @Ancestor() with @Host() @SkipSelf()
Replace @Unbounded() wwith @SkipSelf()
Replace @Ancestor({self:true}) with @Host()
Replace @Unbounded({self:true}) with nothing
Replace new AncestorMetadata() with [new HostMetadata(), new SkipSelfMetadata()]
Replace new UnboundedMetadata() with new SkipSelfMetadata()
Replace new Ancestor({self:true}) with new HostMetadata()
BREAKING CHANGE
The @Parent annotation has been removed. Use @Ancestor instead.
@Parent was used to enforce a particular DOM structure (e.g., a pane component is a direct child of the tabs component).
DI is not the right mechanism to do it. We should enforce it using schema instead.
clang-format 1.0.17 substantially improves formatting for fat arrow functions
and array literal detection. It also fixes a number of minor formatting issues.
BREAKING CHANGE:
Previously, `Directive` was the abstract base class of several directives.
Now, `Directive` is the former `Decorator`, and `Component` inherits from it.
