* Compare final data instead of url
The behavior of did-finish-load and getURL has changed for redirects when
using NetworkService, so the test fails for NetworkService.
Comparing the finally received data makes the test more reliable.
* Implement intercept APIs
* Setting mimeType should set "content-type" header
* Passing no argument should not throw JS error
* Don't access api namespace in ProxyingURLLoaderFactory
* No need to create AtomURLLoaderFactory every time
* No use of weak factory
* fix: always have head.headers available
* fix: use StringDataPipeProducer to write string
It can handle large strings correctly.
* fix: override RegisterNonNetworkSubresourceURLLoaderFactories
* fix: add dummy uninterceptProtocol implementation
* fix: jquery error handler can pass empty string
For some errors jquery would pass empty string in the error handler,
which makes tests pass when they should fail.
* chore: fix cpplint warnings
* fix: guard RegisterNonNetworkSubresourceURLLoaderFactories call
It may be called even when NetworkService is not enabled.
* test: disable protocol.interceptHttpProtocol test
* Pass protocol type and handler to factory
* Add converter for network::ResourceRequest
* Implement Buffer and String protocol handler
* Implement file protocol
