The main use case for the generated source maps is to give
errors a meaningful context in terms of the original source
that the user wrote.
Related changes that are included in this commit:
* renamed virtual folders used for jit:
* ng://<module type>/module.ngfactory.js
* ng://<module type>/<comp type>.ngfactory.js
* ng://<module type>/<comp type>.html (for inline templates)
* error logging:
* all errors that happen in templates are logged
from the place of the nearest element.
* instead of logging error messages and stacks separately,
we log the actual error. This is needed so that browsers apply
source maps to the stack correctly.
* error type and error is logged as one log entry.
Note that long-stack-trace zone has a bug that
disables source maps for stack traces,
see https://github.com/angular/zone.js/issues/661.
BREAKING CHANGE:
- DebugNode.source no more returns the source location of a node.
