Some platforms don't support hostfxr but we can use the coreclr/monosgen library directly to initialize the runtime.
Android exports now use the `android` runtime identifier instead of `linux-bionic`, this removes the restrictions we previously had:
- Adds support for all Android architectures (arm32, arm64, x32, and x64), previously only the 64-bit architectures were supported.
- Loads `System.Security.Cryptography.Native.Android` (the .NET library that binds to the Android OS crypto functions).
The previous packaging format for Godot Android plugins consisted of the plugin's `gdap` config file accompanied by binaries defined in the `gdap` file.
This format is now deprecated (starting with Godot 4.2), and instead Godot Android plugins are now packaged as `EditorExportPlugin` plugins.
The `EditorExportPlugin` class has been updated with the following methods to provide the necessary set of functionality:
- `_supports_platform`: returns true if the plugin supports the given platform
- `_get_android_dependencies`: retrieve the set of android dependencies (e.g: `org.godot.example:my-plugin:0.0.0`) provided by the plugin
- `_get_android_dependencies_maven_repos`: retrieve the urls of the maven repos for the provided android dependencies
- `_get_android_libraries`: retrieve the local paths of the android libraries (AAR files) provided by the plugin
- `_get_android_manifest_activity_element_contents`: update the contents of the `<activity>` element in the generated Android manifest
- `_get_android_manifest_application_element_contents`: update the contents of the `<application>` element in the generated Android manifest
- `_get_android_manifest_element_contents`: update the contents of the `<manifest>` element in the generated Android manifest
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
EditorExportPlugin adds a set of callbacks to allow customizing scenes, resources or subresources in all files exported:
* Can take scene files, resource files and subresources in all of them.
* Uses a cache for the converted files if nothing changes, so this work only happens if a file is modified.
* Uses hashing to differentiate export configuration caches.
* Removed the previous conversion code to binary, as this one uses existing stuff.
This API is useful in several scenarios:
* Needed by the "server" export platform to get rid of textures, meshes, audio, etc.
* Needed by text to binary converters.
* Needed by eventual optimizations such as shader precompiling on export, mesh merging and optimization, etc.
This is a draft, feedback is very welcome.
