<!-- xxxx ------->
The issue came from a lack of support for backtracking on string
matching.
The way it is done, if the "end pattern" for consumeRawText starts with
twice the same character, you end up having problem when your string
being parsed has 3 times this char
Example
End string: xxyz
string to parse: aaaaaaxxxyz
calling consumeRawText(false, 'x', attemptParseStr('xyz')) would fail
Closes#7119
Summary:
This adds basic security hooks to Angular 2.
* `SecurityContext` is a private API between core, compiler, and
platform-browser. `SecurityContext` communicates what context a value is used
in across template parser, compiler, and sanitization at runtime.
* `SanitizationService` is the bare bones interface to sanitize values for a
particular context.
* `SchemaElementRegistry.securityContext(tagName, attributeOrPropertyName)`
determines the security context for an attribute or property (it turns out
attributes and properties match for the purposes of sanitization).
Based on these hooks:
* `DomSchemaElementRegistry` decides what sanitization applies in a particular
context.
* `DomSanitizationService` implements `SanitizationService` and adds *Safe
Value*s, i.e. the ability to mark a value as safe and not requiring further
sanitization.
* `url_sanitizer` and `style_sanitizer` sanitize URLs and Styles, respectively
(surprise!).
`DomSanitizationService` is the default implementation bound for browser
applications, in the three contexts (browser rendering, web worker rendering,
server side rendering).
BREAKING CHANGES:
*** SECURITY WARNING ***
Angular 2 Release Candidates do not implement proper contextual escaping yet.
Make sure to correctly escape all values that go into the DOM.

Impure pipes need to live on the view
that used them and need a new instance for
each call site.
Impure pipes need to live on the component view, cached across all child views,
and need a new pure proxy for each for
each call site that lives on the view
of the call site.
