Remove WebM support (and deps libvpx and opus)
We've had many issues with WebM support and specifically the libvpx library
over the years, mostly due to its poor integration in Godot's buildsystem,
but without anyone really interested in improving this state.

With the new GDExtensions in Godot 4.0, we intend to move video decoding to
first-party extensions, and this would likely be done using something like
libvlc to expose more codecs.

Removing the `webm` module means we can remove libsimplewebm, libvpx and
opus, which we were only used for that purpose. Both libvpx and opus were
fairly complex pieces of the buildsystem, so this is a nice cleanup.

This also removes the compile-time dependency on `yasm`.

Fixes lots of compilation or non-working WebM issues which will be linked
in the PR.

Third party libraries

Please keep categories (## level) listed alphabetically and matching their respective folder names. Use two empty lines to separate categories for readability.

basis_universal

Files extracted from upstream source:

  • encoder/ and transcoder/ folders
  • LICENSE

bullet

Files extracted from upstream source:

  • src/* apart from CMakeLists.txt and premake4.lua files
  • LICENSE.txt, and VERSION as VERSION.txt

Includes some patches in the patches folder which have been sent upstream.

certs

cvtt

Files extracted from upstream source:

  • all .cpp, .h, and .txt files in ConvectionKernels/

doctest

Extracted from .zip provided. Extracted license and header only.

embree

Files extracted from upstream:

  • All cpp files listed in modules/raycast/godot_update_embree.py
  • All header files in the directories listed in modules/raycast/godot_update_embree.py

The modules/raycast/godot_update_embree.py script can be used to pull the relevant files from the latest Embree release and apply some automatic changes.

Some changes have been made in order to remove exceptions and fix minor build errors. They are marked with // -- GODOT start -- and // -- GODOT end -- comments. Apply the patches in the patches/ folder when syncing on newer upstream commits.

enet

  • Upstream: http://enet.bespin.org
  • Version: 1.3.17 (e0e7045b7e056b454b5093cb34df49dc4cee0bee, 2020)
  • License: MIT

Files extracted from upstream source:

  • all .c files in the main directory (except unix.c win32.c)
  • the include/enet/ folder as enet/ (except unix.h win32.h)
  • LICENSE file

Important: enet.h, host.c, protocol.c have been slightly modified to be usable by Godot's socket implementation and allow IPv6 and DTLS. Apply the patches in the patches/ folder when syncing on newer upstream commits.

Three files (godot.cpp, enet/godot.h, enet/godot_ext.h) have been added to provide enet socket implementation using Godot classes.

It is still possible to build against a system wide ENet but doing so will limit its functionality to IPv4 only.

Files extracted from upstream source:

  • Only the files relevant for compression (i.e. Process*.cpp and their deps):
