BREAKING_CHANGE:
- The special type of `Viewport` directives is removed
in favor of a more general `Decorator` directive
- `ViewContainerRef` now no more has a default `ProtoViewRef`
but requires an explicit one when creating views.
Closes#1536
Add utility methods to convert `render.dom.DirectiveMetadata` to and
from maps. This will allow saving and restoring `DirectiveMetadata` in
the Angular 2 Transformer.
We discussed adding this as a member on `DirectiveMetadata`. Since this
is not necessary for anything except the Transformer, we decided to put
it into a separate file to avoid shipping it with the Angular 2 core
code.
BREAKING CHANGES:
- `NgElement` merged into `ElementRef`
- `Compiler.compile…` returns `ProtoViewRef`
- `ViewContainer` uses `ProtoViewRef`s and `ViewRef`s.
- `ViewRef`/`ProtoViewRef` in renderer were renamed to
`RenderViewRef`/`RenderProtoViewRef`.

AppViewManager is the single entry point to changing the view hierarchy.
It is split between the manager itself which does coordination and
helper methods, so both are easily testable in isolation.
Also, ViewContainer is now only a pure reference to a bound element
with the previous functionality but does not contain the list of views
any more.
Part of #1477
Add two transform parameters to aid in debugging the transformer
- `mirror_mode`, with values {`debug`, `none`, and `verbose`}
- `init_reflector`, with values {`true`, `false`}
`mirror_mode`:
- `debug`: Allow reflective access, but log a message if it is used
- `none`: Remove reflective access, `throw` if it is used. Default value
- `verbose`: Allow reflective access, log a stack trace if it is used
`init_reflector`: Whether to generate calls to our generated
`initReflector` code.
These will be useful to reveal areas where the transformer is not generating
appropriate code and to quickly see where reflective accesses occur.
When the pub mode is `transform_dynamic`, we run in MirrorMode.debug
with `init_reflector = false`. This is used for testing purposes.
Previously, light dom nodes that were not used by any content tag
were not removed from a view on redistribute. This lead
to a bug when reusing a view from the view pool, as it
still contained stale reprojected nodes.
Fixes#1416
Major changes:
- `compiler.compileRoot(el, type)`
-> `compiler.compileInHost(type) + viewHydrator.hydrateHostViewInPlace(el, view)`
- move all `hydrate`/`dehydrate` methods out of `View` and `ViewContainer` into
a standalone class `view_hydrator` as private methods and provide new public
methods dedicated to the individual use cases.
Note: This PR does not change the current functionality, only moves it
into different places.
See design discussion in #1351, in preparation for imperative views.
