Start using WebURLLoader, et. al. from the WebKit API.

Moves our ResourceHandle to webkit/api/src/ResourceHandle.cpp
from webkit/glue/resource_handle_impl.cc.  A portion of
resource_handle_impl.cc was moved into weburlloader_impl.{h,cc},
which now contains our implementation of WebURLLoader.

The annoying parts of this CL involve WebPluginImpl.  I had to
convert it over to using WebURLLoader instead of ResourceHandle
so that MultipartResourceDelegate can be shared. 

There is some complexity in WebURLRequest / WebURLResponse to
make it cheap to wrap a ResourceRequest / ResourceResponse.  I
think this is worth it since there is a lot of conversion between
the two types.
