eaedc92c61 [HTML5] Use absolute path for JS lib/pre/externs.
Ensure better compatibility when emcc which may run some tools from
different paths (e.g. closure compiler).

This fixes externs include issues with modern emcc using the closure
compiler.

b2d30c725d [HTML5] Implement mouse/touch/key events in JS library.
This makes us more independent from emscripten libraries, giving us more
control on the application lifecycle.

14c057eab6 [HTML5] Fix GDNative compilation with emcc 2.0.19+
Add `WARN_ON_UNDEFINED_SYMBOLS=0` for the main module (which defines
`godot_js_main` as extern coming from the "side" module, i.e. the main
Godot binary).

d8bd54fbf2 [HTML5] Add PWA support to the editor page.
This allows to install it as an app, and provide offline support (after
the first run).
Practically, this boils down to adding a JSON file as a manifest, an
offline page to be displayed when the cached files are not avaialble,
and a JS file to cache resources and return them.

The reason for the "first run requirements" is that some browsers, will
emit an "install" by just visiting the page (to see if the JS code is
compatibile), and we do not want to force casual visitors to just
download the 10 MiB+ compressed editor WebAssembly file without pressing
the start button.

Special thanks to Hugo Locurcio (Calinou) for the initial work.

4404eb57e4 [HTML5] Make editor HTML build tag scons4-proof.
We used to have it like `$GODOT_VERSION` which caused inconsistencies
between different scons versions when substituting it.
It's now `@GODOT_VERSION@`, which is safe on both scons3 and scons4.

a82f70ea9f [HTML5] Libraries refactor for linting.
Initial work to make liniting easier.

This includes:
- Rename http_request.js to library_godot_http_request.js.
- Rename externs.js to engine.externs.js.
- New library_godot_runtime.js (GodotRuntime) wraps around emscripten
  functions.
- Refactor of XMLHttpRequest handler in engine/preloader.js.
- Few fixes to bugs spotted by early stage linting.

179ec3ca0e [HTML5] AudioWorklet API implementation.
Rewrote AudioDriverJavaScript to support multiple processor nodes.
The old (and deprecated) ScriptProcessorNode when threads are not
available, and the new AudioWorklet API when threads are enabled.

The new implementation uses two ring buffers and a shared state to
communicated with the AudioWorklet thread.

The audio.worklet.js JavaScript file is always added to the export
template, but only really used (and downloaded) in the thread build.

e2083871eb [HTML5] Port JavaScript inline code to libraries.
The API is implemented in javascript, and generates C functions that can
be called from godot.
This allows much cleaner code replacing all `EM_ASM` calls in our C++
code with plain C function calls.
This also gets rid of few hacks and comes with few optimizations (e.g.
custom cursor shapes should be much faster now).

c54de7f589 [HTML5] Add JavaScriptToolsEditorPlugin.
A new editor plugin, specific to HTML5, that provide some extra features
needed to make the editor usable on that platform.

For now, it adds a "Download project sources" option in the "Tool" menu,
so the user can download the work done as a zip file (from the browser
storage).

a618535628 [HTML5] Run Audio process in thread when available
This should fix some of the audio stuttering issues when the HTML5
export is compiled with threads support.
The API should be ported to AudioWorklet to (hopefully) be perfect.
That though, cannot be backported to 3.2 due to extra restriction of
AudioWorklet (which only runs in SecureContext, and needs a polyfill for
Safari).

cd4e46ee65 SCons: Format buildsystem files with psf/black
Configured for a max line length of 120 characters.

psf/black is very opinionated and purposely doesn't leave much room for
configuration. The output is mostly OK so that should be fine for us,
but some things worth noting:

- Manually wrapped strings will be reflowed, so by using a line length
  of 120 for the sake of preserving readability for our long command
  calls, it also means that some manually wrapped strings are back on
  the same line and should be manually merged again.

- Code generators using string concatenation extensively look awful,
  since black puts each operand on a single line. We need to refactor
  these generators to use more pythonic string formatting, for which
  many options are available (`%`, `format` or f-strings).

- CI checks and a pre-commit hook will be added to ensure that future
  buildsystem changes are well-formatted.

919bbf8077 [HTML5] Refactor JS, threads support, closures.
- Refactored the Engine code, splitted across files.
- Use MODULARIZE option to build emscripten code into it's own closure.
- Enable lto support (saves ~2MiB in release).
- Enable optional closure compiler pass for JS and generated code.
- Enable optional pthreads support.
- Can now build with tools=yes (not much to see yet).
- Dropped some deprecated code for older toolchains.

68422c5dd6 Relink web build when HTML shell changes
Emscripten injects its loader script when linking, so force relinking

Also remove useless FULL_ES2 flag, which should be a linker flag, but
would impact performance too much.
