Make GetAlternateProtocolRequestFor return AlternativeService.

Make HttpStreamFactoryImpl::GetAlternateProtocolRequestFor() return
AlternativeService instead of AlternateProtocolInfo, and rename it to
GetAlternativeServiceRequestFor.  Also change the type and name of
HttpStreamFactoryImplJob.{,other_job_}alternate_protocol_.
