12306728c5 Add system ID entropy API 
The `zend_system_id` is a (true global) system ID that fingerprints a process state. When extensions add engine hooks during MINIT/startup, entropy is added the system ID for each hook. This allows extensions to identify that changes have been made to the engine since the last PHP process restart.

Closes GH-5871

34bb5ba2ea Remove support for EXT_NOP 
This is an annoying edge case that regularly gets broken. As we're
not aware of significant users of this API, and there are other
ways to hook this, remove support for EXT_NOP.
