Reviewed by Sam Weinig.

We'll just send all requests to CFNetwork now, along with associated priorities.

* WebCore.exp.in: WebKitSystemInterface functions are changing to support priorities
for more than just pipelining.
* loader/ResourceLoadScheduler.cpp:
(WebCore::ResourceLoadScheduler::scheduleLoad):
* platform/ios/WebCoreSystemInterfaceIOS.mm:
* platform/mac/WebCoreSystemInterface.h:
* platform/mac/WebCoreSystemInterface.mm:
* platform/network/ResourceHandle.h: For syncronous requests, make it so that they
don't count against HTTP connection limit, to avoid the possibility of hanging the process.
* platform/network/cf/ResourceHandleCFNet.cpp:
(WebCore::ResourceHandle::createCFURLConnection):
(WebCore::ResourceHandle::start):
(WebCore::ResourceHandle::platformLoadResourceSynchronously):
* platform/network/cf/ResourceRequestCFNet.cpp:

for new WKSI function names.

Reviewed by Sam Weinig.

* NetworkProcess/mac/NetworkResourceLoadSchedulerMac.mm:
(WebKit::NetworkResourceLoadScheduler::platformInitializeMaximumHTTPConnectionCountPerHost):
We no longer need the trick with 7 connections, as synchronous requests always have
the right of way.

* UIProcess/API/C/WKContext.cpp: Removed long obsolete functions.

* WebProcess/WebCoreSupport/mac/WebSystemInterface.mm: (InitWebCoreSystemInterface):
Updated for new WKSI function names.

Update WKSI.
