* PHPC-1805: Implement ServerDescription class
* PHPC-1910: Implement Server::getServerDescription()
* PHPC-1934: Check for uninitialized intern in ServerDescription get_properties_hash
* PHPC-1925: Change ServerDescription::getType() to return a string
* PHPC-1891: Implement TopologyDescription class
* PHPC-1892: Implement SDAMSubscriber interface
* PHPC-1893: Implement SDAM event classes
* Revise server and topology event classes and tests
Use phongo_objectid_init in getTopologyId() methods. Report topologyId as an ObjectId in debug info. Report TopologyDescription servers as ServerDescription in debug info.
Copy parameters in phongo_serverdescription_init and phongo_topologydescription_init for consistency with other functions (e.g. phongo_readconcern_init). This also creates phongo_serverdescription_init_ex for when we want to skip copying in Server::getServerDescription().
* PHPC-1953: Add tests for debug handlers
* PHPC-1959: Utilize Manager::addSubscriber() in tests
Skip TopologyClosedEvent test (pending PHPC-2023)
* PHPC-1958: Assert same topologyId for SDAM events
* PHPC-2025: Support load balancer in ServerDescription and TopologyDescription
* PHPC-2026: Handle 64-bit lastUpdateTime for 32-bit platforms
