Subject: This CL moves the different resource handlers from
resource_dispatcher_host.cc into their own files, into a new renderer_host
directory. Their is no functionality change in this CL.
The motivation for doing that was:
- resource_dispatcher_host.cc has become very long and more than 1/3 of the code is for the resource handler.
- having the resource handler in their own file allows having unit tests for them.
BUG=none
TEST=run all unit tests and UI tests.
