+ WebKit may keep outdated entry in the disk cache after a reload

+ <rdar://problem/22299547>
+
+ Reviewed by Antti Koivisto.
+
+ WebKit would keep outdated entry in the disk cache after a reload
+ in the following scenario:
+ 1. We have an entry in the cache
+ 2. The user reloads
+ 3. We get a fresh resource from the network but this one is not cacheable
+
+ In this case, we now remove the stale entry from the cache to make sure
+ it is not served to following requests (e.g. history navigations).
+
+ * NetworkProcess/NetworkResourceLoader.cpp:
+ (WebKit::NetworkResourceLoader::didFinishLoading):
+ Remove the entry from the cache if its redirection is no longer
+ cacheable.
+
+ * NetworkProcess/cache/NetworkCache.cpp:
+ (WebKit::NetworkCache::Cache::store):
+ If we make the decision not to store the response, then remove the
+ entry in the cache for this resource if it exists.
+
+ (WebKit::NetworkCache::Cache::remove):
+ * NetworkProcess/cache/NetworkCache.h:
+ Add new remove() overload taking a ResourceRequest argument so the
+ call site does not have the compute the key.
+
+ * NetworkProcess/cache/NetworkCacheStorage.cpp:
+ (WebKit::NetworkCache::Storage::removeFromPendingWriteOperations):
+ (WebKit::NetworkCache::Storage::remove):
+ * NetworkProcess/cache/NetworkCacheStorage.h:
+ When we're asked to remove an entry with a given key, also remove
+ it from the pending write operations. This pre-existing bug would
+ prevent the new layout test from passing.
