Retrofit the pre-existing appache message dispatching with the new WebKit APIs and concrete classes defined in our new appcache library, and get rid of the old files.

There are many files in the CL, mostly to pickup constant values now defined in our new appcache library, and to reflect a terminilogy change (from 'context' to 'host').

TEST=some existing unit tests apply
BUG=none
