>+        Move NetworkStorageSession ownership to NetworkProcess

>+
>+        NetworkStorageSessions used to be owned by a process-global map living in WebCore.
>+        This patch moves the ownership to the WebKit/WebKitLegacy layer.
>+        In WebKitLegacy they are still owned by a process-global map for compatibility.
>+        In WebKit they are owned by a map owned by the NetworkProcess object.
>+        There were three non-NetworkProcess uses of NetworkStorageSessions which have been dealt with thusly:
>+        1. The WebProcess used to clear credentials from a NetworkStorageSession.  Since this was the only use
>+        of a NetworkStorageSession in the WebProcess we can conclude there were no credentials to clear,
>+        so this code was removed with no change in behavior.
>+        2. The WebProcess used NetworkStorageSessions to get persistent credentials.  This was turned
>+        into a static method that does the same thing.  We should audit these calls and decide if we really want them.
>+        3. The UIProcess used NetworkStorageSessions in APIHTTPCookieStore to interact with the default cookie
>+        storage on Cocoa platforms.  This has been replaced by functions that do the same thing directly.
