+ [Cocoa] Media elements will restart network buffering just before suspending
+ https://bugs.webkit.org/show_bug.cgi?id=193691
+
+ Reviewed by Eric Carlson.
+
+ When the WebProcess receives a notification that the process is about to become
+ suspended, it tells the MemoryPressureHandler to release all critical memory. This
+ has the side effect of causing AVFoundation-backed media elements to dump their
+ in-memory caches and start downloading media data again. Instead, media elements
+ should all stop buffering media data during suspension. Add new testing SPI to
+ simulate suspension and resume messages.
