2022-05-16Replace most uses of Map by HashMapreduz
* Map is unnecessary and inefficient in almost every case. * Replaced by the new HashMap. * Renamed Map to RBMap and Set to RBSet for cases that still make sense (order matters) but use is discouraged. There were very few cases where replacing by HashMap was undesired because keeping the key order was intended. I tried to keep those (as RBMap) as much as possible, but might have missed some. Review appreciated!
2022-05-12Add a new HashMap implementationreduz
Adds a new, cleaned up, HashMap implementation. * Uses Robin Hood Hashing (https://en.wikipedia.org/wiki/Hash_table#Robin_Hood_hashing). * Keeps elements in a double linked list for simpler, ordered, iteration. * Allows keeping iterators for later use in removal (Unlike Map<>, it does not do much for performance vs keeping the key, but helps replace old code). * Uses a more modern C++ iterator API, deprecates the old one. * Supports custom allocator (in case there is a wish to use a paged one). This class aims to unify all the associative template usage and replace it by this one: * Map<> (whereas key order does not matter, which is 99% of cases) * HashMap<> * OrderedHashMap<> * OAHashMap<>

2022-02-21[Net] Fix multi-peer path-only replication.Fabio Alessandrelli
It used to check if a net_id was ever assigned to that node to detect when to send the path confirm to the remote peer. This is wrong, because the same net_id is shared for all the remote peers, but sent one by one. Instead we now check if it's either not assigned or if the assigned net_id is a cache ID, and in that case ensure that the remote peer has been notified. This can be further improved by unifying the cache interface, but for now it's a fast fix to get path-only sync to work.

Also splits bandwidth/rpc profiler (RPCProfiler is now in SceneDebugger).
2022-02-05[Net] Move RPC, Node cache out of MultiplayerAPI.Fabio Alessandrelli
Now uses two interfaces so it can be overridden in the future, and core no longer depends on Node. The interfaces are implements in scene/multiplayer. Replaces root_node with root_path. Remove all Node references from MultiplayerAPI.
2022-02-04[Net] New replication interface, spawner and synchronizer nodes.Fabio Alessandrelli
Initial implementation of the MultiplayerReplicationInterface and its default implementation (SceneReplicationInterface). New MultiplayerSpawner node helps dealing with instantiation of scenes on remote peers (e.g. clients). It supports both custom spawns via a `_spawn_custom` virtual function, and optional auto-spawn of known scenes via a TypedArray<PackedScenes> property. New MultiplayerSynchornizer helps synchronizing states between the local and remote peers, supports both sync and spawn properties and is configured via a `SceneReplicationConfig` resource. It can also sync via path (i.e. without being spawned by a MultiplayerSpawner if both peers has it in tree, but will not send the spawn state in that case, only the sync one.
