Migrate core plugins to C?

[ItsZariep]

As the title says, it might be a good idea to migrate core plugins to C. In recent months, most rolling release systems, like Arch Linux, have broken Xed plugins because:

Remove python3 loader
The loader is nonfunctional as of pygobject 3.52 because the latter was ported to libgirepository-2.0, which cannot be loaded together with libgirepository-1.0, which libpeas still depends on.

As a consequence, core Xed plugins written in Python don’t load because the plugin loader fails:

(xed:19216): libpeas-WARNING **: 12:31:31.714: Failed to load module 'python3loader': /usr/lib/libpeas-1.0/loaders/libpython3loader.so: cannot open shared object file: No such file or directory

(xed:19216): libpeas-WARNING **: 12:31:31.714: Could not load plugin loader 'python3'

** (xed:19216): WARNING **: 12:31:31.714: Failed to load builtin plugin: Text Size

** (xed:19216): WARNING **: 12:31:31.714: Failed to load builtin plugin: Join Lines

** (xed:19216): WARNING **: 12:31:31.714: Failed to load builtin plugin: Open URI

This has happened multiple times already, so I propose migrating these plugins to C, as some plugins, like Text Size, are fundamental features.

Plugins written in C don’t have this problem. I’m currently rewriting these plugins in C but I’m not sure if there are any considerations I should keep in mind during the process.
