Fabio Alessandrelli 9fcf3b5a9c [Net] Basic extensible MultiplayerAPI spawn/despawn.
`PackedScene`s can be configured to be spawnable via a new
`MultiplayerAPI.spawnable_config` method.
They can be configured either to be spawned automatically when coming
from the server or to always require verification.
Another method, `MultiplayerAPI.send_spawn` lets you request a spawn on
the remote peers.
When a peer receive a spawn request:
- If it comes from the server and the scene is configured as
  `SPAWN_MODE_SERVER`:
  - Spawn the scene (instantiate it, add it to tree).
  - Emit signal `network_spawn`.
- Else:
  - Emit signal `network_spawn_request`.

In a similar way, `despawn`s are handled automatically in
`SPAWN_MODE_SERVER`.

In `SPAWN_MODE_SERVER`, when a new client connects it will also receive,
from the server all the spawned (and not yet despawned) instances.

Fabio Alessandrelli ddb68f76ff [Net] Single `rpc` annotation. "sync" no longer part of mode.
- Move the "sync" property for RPCs to RPCConfig.

- Unify GDScript annotations into a single one:
  - `@rpc(master)` # default
  - `@rpc(puppet)`
  - `@rpc(any)` # former `@remote`

- Implement three additional `@rpc` options:
  - The second parameter is the "sync" option (which also calls the
    function locally when RPCing). One of "sync", "nosync".
  - The third parameter is the transfer mode (reliable, unreliable,
    ordered).
  - The third parameter is the channel (unused for now).

reduz 6631f66c2a Optimize StringName usage
* Added a new macro SNAME() that constructs and caches a local stringname.
* Subsequent usages use the cached version.
* Since these use a global static variable, a second refcounter of static usages need to be kept for cleanup time.
* Replaced all theme usages by this new macro.
* Replace all signal emission usages by this new macro.
* Replace all call_deferred usages by this new macro.

This is part of ongoing work to optimize GUI and the editor.

Fabio Alessandrelli d779b5aa3e [Net] Refactor RPCs, remove RSETs
In this PR:
- Removed rset
- rpc_config can now optionally configure transfer mode
  (reliable/unreliable/ordered) and channel (channels are not actually
  implemented yet.)
- Refactor how the RPC id is computed to minimize the logic in Node and
  scripts that now only needs a single `get_rpc_methods` function.

Core: Drop custom `copymem`/`zeromem` defines
We've been using standard C library functions `memcpy`/`memset` for these since
2016 with 67f65f6639.

There was still the possibility for third-party platform ports to override the
definitions with a custom header, but this doesn't seem useful anymore.

Kyle 74379b15ff MultiplayerAPI is_network_server Fails Silently
Removes the error message when the network peer is not valid and returns false instead.

This makes it simpler to make games that are both on/offline by replacing server checks of

'''
if is_instance_valid(get_tree().network_peer) and get_tree().is_network_server():
		# Do server things
'''

with

'''
if get_tree().is_network_server():
		# Do server things
'''

Requires no changes to the docs because both the MultiplayerAPI and SceneTree docs don't mention the error.

Update copyright statements to 2021
Happy new year to the wonderful Godot community!

2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.

We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)

Here's to a great year 2021 for all Godot users 🎆

Rémi Verschelde 0ee0fa42e6 Style: Enforce braces around if blocks and loops
Using clang-tidy's `readability-braces-around-statements`.

Rémi Verschelde 07bc4e2f96 Style: Enforce separation line between function definitions
I couldn't find a tool that enforces it, so I went the manual route:
```
find -name "thirdparty" -prune \
  -o -name "*.cpp" -o -name "*.h" -o -name "*.m" -o -name "*.mm" \
  -o -name "*.glsl" > files
perl -0777 -pi -e 's/\n}\n([^#])/\n}\n\n\1/g' $(cat files)
misc/scripts/fix_style.sh -c
```

This adds a newline after all `}` on the first column, unless they
are followed by `#` (typically `#endif`). This leads to having lots
of places with two lines between function/class definitions, but
clang-format then fixes it as we enforce max one line of separation.

This doesn't fix potential occurrences of function definitions which
are indented (e.g. for a helper class defined in a .cpp), but it's
better than nothing. Also can't be made to run easily on CI/hooks so
we'll have to be careful with new code.

Part of #33027.

Rémi Verschelde 0be6d925dc Style: clang-format: Disable KeepEmptyLinesAtTheStartOfBlocks
Which means that reduz' beloved style which we all became used to
will now be changed automatically to remove the first empty line.

This makes us lean closer to 1TBS (the one true brace style) instead
of hybridating it with some Allman-inspired spacing.

There's still the case of braces around single-statement blocks that
needs to be addressed (but clang-format can't help with that, but
clang-tidy may if we agree about it).

Part of #33027.

Rémi Verschelde 1f6f364a56 Port member initialization from constructor to declaration (C++11)
Using `clang-tidy`'s `modernize-use-default-member-init` check and
manual review of the changes, and some extra manual changes that
`clang-tidy` failed to do.

Also went manually through all of `core` to find occurrences that
`clang-tidy` couldn't handle, especially all initializations done
in a constructor without using initializer lists.

Rémi Verschelde e956e80c1f Style: clang-format: Disable AllowShortIfStatementsOnASingleLine
Part of #33027, also discussed in #29848.

Enforcing the use of brackets even on single line statements would be
preferred, but `clang-format` doesn't have this functionality yet.

Fabio Alessandrelli b8ddaf9c33 Refactor ScriptDebugger.
EngineDebugger is the new interface to access the debugger.
It tries to be as agnostic as possible on the data that various
subsystems can expose.

It allows 2 types of interactions:

- Profilers:
  A subsystem can register a profiler, assigning it a unique name.
  That name can be used to activate the profiler or add data to it.
  The registered profiler can be composed of up to 3 functions:
    - Toggle: called when the profiler is activated/deactivated.
    - Add: called whenever data is added to the debugger
      (via `EngineDebugger::profiler_add_frame_data`)
    - Tick: called every frame (during idle), receives frame times.

- Captures: (Only relevant in remote debugger for now)
  A subsystem can register a capture, assigning it a unique name.
  When receiving a message, the remote debugger will check if it starts
  with `[prefix]:` and call the associated capture with name `prefix`.

Port MultiplayerAPI, Servers, Scripts, Visual, Performance to the new
profiler system.

Port SceneDebugger and RemoteDebugger to the new capture system.
The LocalDebugger also uses the new profiler system for scripts
profiling.

Rémi Verschelde 01afc442c7 Signals: Port connect calls to use callable_mp
Remove now unnecessary bindings of signal callbacks in the public API.
There might be some false positives that need rebinding if they were
meant to be public.

(Nah, just kidding.)

Also enables -Wimplicit-fallthrough for Clang now that we can properly
support it. It's already on by default for GCC's -Wextra.

Fixes new warnings raised by Clang's -Wimplicit-fallthrough.

Rémi Verschelde 8d00a3a536 Remove deprecated PacketPeer allow_object_decoding

it for the internal put_var calls.

Andrea Catania eb07e87981 Optmized data sent during RPC and RSet calls.
- Now is sent the method ID rather the full function name.
- The passed IDs (Node and Method) are compressed so to use less possible space.
- The variant (INT and BOOL) is now encoded and compressed so to use much less data.
- Optimized RPCMode retrieval for GDScript functions.
- Added checksum to assert the methods are the same across peers.
