libcef:

- Fix incorrect result in CefBytesReader::Seek() when SEEK_END argument is specified.
- Return 0 from CefBytesReader::Seek() on success to be consistent with fseek().
- Set URLRequestStatus error code to net::ERR_ABORTED in browser_resource_loader_bridge.cc when HandleBeforeResourceLoad returns RV_HANDLED to avoid a WebKit assert.

unittests:
- Add unit testing framework.
- Add initial unit tests for request, stream and V8.
