[HTML5] Fix multi-touch input handling.
The code to populate the input data for WebAssembly was incorrectly
overriding values when multiple touches were present due to wrong
indexing.

Fabio Alessandrelli bbfe054175 [HTML5] Use compatibility function for glGetBufferSubData.
The "webgl/webgl2.h" include provides that function, but it's not
available in emscripten versions < 2.0.17 .

Since we need to support emscripten 1.39.9 (mono builds), this commit
adds a JS function in library_godot_display.js as a compatibility layer
for it, and implement glGetBufferSubData by funneling the call to that
function (so we don't have name collisions JS-side with recent emcc).

All those hacks are now moved to the platform directory instead of being
ifdefs inside the drivers implementations.

[HTML5] Fix focus (again) in Firefox's iframes.
This actually makes sense(?), when running inside an iframe the active
element might be our canvas, while the iframe itself is not active in
the parent window. Since we consume the event, the iframe does not get
focused in Firefox (but does in Chromium-based browsers), so we must
always call focus to handle such occasions.

[HTML5] Add checks to Gamepad API events.
In some conditions the events might be generated even when the `gamepad`
object is not accessible due to Security Context requirements.
This commit adds a check to avoid firing the handler in those cases.

HTML5: Fix minification error with Emscripten 1.39.9
It used an old vendored version of acorn.js which seems to choke on this
trailing comma. This is not a problem for more recent Emscripten versions.

We disable the `comma-dangle` check in ESLint to prevent this issue.

Fabio Alessandrelli 2024200182 [HTML5] Refactor audio drivers. Implement AudioWorklet w/o threads.
Performances are not great in general, bad on Firefox, on Chrome, well,
it's an improvement compared to the way they broke ScriptProcessorNode.

I'm actually surprised this works, it involves so many allocations, but
there's no way around it when SharedArrayBuffer is not available :(.

Fabio Alessandrelli b800438efb [HTML5] Use browser mix rate by default on the Web.
Browsers doesn't really like forcing the mix rate, e.g. Firefox does not

will exhibit worse performances, etc.

[HTML5] Disable body_size in fetch.
We were using `Content-Length` from the server when `Content-Encoding`
was not set (i.e. response was not compressed).

Sadly, in CORS requests accessing headers is restricted, and while
`Content-Length` is enabled by default, `Content-Encoding` is not.

This results in the impossibility of knowing if the content was
compressed, unless the server explicitly enabled the encoding header
via `Access-Control-Expose-Headers`.

To keep maximum compatibility we must disable `body_size` completely.

Fabio Alessandrelli 64feaed39b [HTML5] Drag and drop zip in project manager.
With a very nice hack, a new hidden configuration option that delays
dropped files removal at exit.

This still leaks while the project manager is running, but will clear
memory as soon as it exits or load something.
(reminder, dropped files are reguarly removed after the signal is
emitted specifically to avoid leaks, but I prefer hacking the HTML5
config then the project manager).

Fabio Alessandrelli 82b900bdda [HTML5] Properly set canvas size during setup.
It used to be updated before the first iteration, causing the

phase (e.g. during the first `_ready` notification).

Fabio Alessandrelli 4b38aefd33 [HTML5] Opt-in virtual keyboard support.
Added as an export option "Experimental Virtual Keyboard".
There is no zoom, so text/line edit must be in the top part of the
screen, or it will get hidden by the virtual keyboard.
UTF8/Latin-1 only (I think regular UTF-8 should work out of the box in
4.0 but I can't test it).
It uses an hidden textarea or input, based on the multiline variable,
and only gets activated if the device has a touchscreen.
This could cause problems on devices with both touchscreen and a real
keyboard (although input should still work in general with some minor
focus issues). I'm thinking of a system to detect the first physical
keystroke and disable it in case, but it might do more harm then good,
so it must be well thought.

Fabio Alessandrelli 45a67fab35 [HTML5] Better fullscreen, canvas resizing.
Three canvas resize policies:
- `None`: Godot window settings are ignored.
- `Project`: Godot handles the canvas like a native app (resizing it
  when setting the window size).
- `Adaptive`: Canvas size will always adapt to browser window size.

Use `None` if you want to control the canvas size with custom JavaScript
code.

`OS.get_screen_scale` will now return the `window.devicePixelRatio`

DPI value for the current display.
`OS.get_screen_size` also return the actual screen size (not the CSS
pixel size).

Fabio Alessandrelli 31b5c5ee03 [HTML5] Custom Gamepad library to allow remapping.
No longer use emscripten functions for gamepads, implement them as
library functions in library_godot_display.js instead.
This allows us to do a better job at "guessing" vendorId, productId, OS,
etc. thus allowing us to better find the remapping for the controller.

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 🎆
