Reviewed by Sam Weinig.

Source/WebCore:

In order to support converting NSURLConnections to NSURLDownloads when using the network process
we need an async version of didReceiveResponse.

* WebCore.exp.in:
* platform/network/ResourceHandleClient.cpp:
(WebCore::ResourceHandleClient::didReceiveResponseAsync):
Just call continueDidReceiveResponse().

* platform/network/mac/ResourceHandleMac.mm:
(WebCore::ResourceHandle::continueWillSendRequest):
Split up a single condition in two, making it easier to see which assertion fails.

(WebCore::ResourceHandle::continueDidReceiveResponse):
Call -[WebCoreResourceHandleAsOperationQueueDelegate continueDidReceiveResponse].

(WebCore::ResourceHandle::continueShouldUseCredentialStorage):
(WebCore::ResourceHandle::continueCanAuthenticateAgainstProtectionSpace):
(WebCore::ResourceHandle::continueWillCacheResponse):
Split up a single condition in two, making it easier to see which assertion fails.

* platform/network/mac/WebCoreResourceHandleAsOperationQueueDelegate.h:
* platform/network/mac/WebCoreResourceHandleAsOperationQueueDelegate.mm:
(-[WebCoreResourceHandleAsOperationQueueDelegate continueDidReceiveResponse]):
Signal the semaphore.

(-[WebCoreResourceHandleAsOperationQueueDelegate connection:didReceiveResponse:]):
Call didReceiveResponseAsync on the main thread and wait on the semaphore.

Source/WebKit2:

* NetworkProcess/NetworkResourceLoader.cpp:
(WebKit::NetworkResourceLoader::didReceiveResponseAsync):
Send the message and then call continueDidReceiveResponse.
