AppCacheDatabase and SQL based AppCacheStorageImpl.

Still nothing is being written to disk with this CL, 
in-memory SQLite and DiskCaches are being utilized. 
Responses are not yet being removed from the DiskCasche 
when the should be. Once that's done (in the next CL), we'll 
start saving things on disk. 

BUG=none 
TEST=appcache_database_unittest.cc, appcache_storage_impl_unittest.cc
