Took the opportunity to undo the Godot changed made to the
opus source. The opus module should eventually be built in its
own environment to avoid polluting others with too many include
dirs and defines.
TODO: Fix the platform/ stuff for opus.
(cherry picked from commit d9a291f641)
speex module was only added while cherry-picking, as speex is removed
in the master branch but we don't want to break compatibility in 2.1.x.
Unbundling wasn't done as the module uses the internal speex_free,
so it would require some more work.
Note that there are two Godot-specific changes made to libwebp
for the javascript/HTML5 platform. They are documented in the
README.md.
(cherry picked from commit ee3cf211c6)
Uses the new structure agreed upon in #6157, but the thirdparty/ folder
does not behave following a logic similar to that of modules/ yet.
The png driver can't be moved to a module as discussed in #6157, as it's
required by core together with a few other ImageLoader implementations
(see drivers/register_driver_types.cpp:register_core_driver_types())
Dropped the possibility to disable PNG support, it's a core component
of Godot.

* This allows building when ALSA libs are in a non-standard location. PKG_CONFIG_PATH alone is not enough as the final link fails. Adding this makes the final link succeed.
* The extra LIBS flag for alsa is not needed so removing.

This allows us not to have to hack our definitions in the upstream files,
making it easier to upgrade to newer versions in the future.
For the include paths to work, the headers are moved to a GL subfolder to
match their upstream location.
It is enabled by default, users have to specifically ask for it if they don't want gamepad support. If libudev or libevdev are missing, the build aborts and tells the user the reason and that they can disable gamepad support with the "gamepad=no" option.
Test if clang is defined in CC/CXX/LD - this allows a specific version of clang to be defined
move appending -DTYPED_METHOD_BIND to keep clang options together
move sanitize option out of use_llvm test, gcc48+ also supports sanitize=address
