HttpContentRenderer has been renamed to FragmentHandler.
The RendererStrategy subnamespace has been renamed to Fragment.
The strategy classes now have Fragment in their names.
ProxyRouterListener has been renamed to FragmentListener
The router_proxy configuration entry has been renamed to fragments.
The previous code allowed to pass null as a Request but that does not
really make sense as rendering a sub-request can only happen from a
master request. This was done to ease testing but that was a mistake.

[Form] Fixed variable passing from outer to inner blocks of the same FormView instance
Bug fix: yes
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: yes
Fixes the following tickets: #5029
Todo: -
This PR fixes two bugs.
The first bug is described in #5029. The second parameter to the "form_label" function in Twig, if given, always overwrote whatever label was defined previously.
```
{# null would overwrite whatever is currently set #}
form_label(form, null, { ... })
```
The second bug affected passing variables from outer to inner blocks. In the following example, "label_attr" would not be forwarded to the "form_label" function.
```
form_row(form, { "label_attr": { "class": "my_class" }})
```
Both bugs are fixed now.
