RevoluPowered 5a6f275b74 Added compilation database support for clang and gcc
This tool is originally from mongodb.

- Updated CPPSUFFIXES to use scons suffixes
- objective-c files will also be loaded into the compilation database where the compiler / tooling is available to compile the files.

Known limitations:

- This will not work with msvc as your compiler.

Rémi Verschelde 26ab805c78 SCons: Disable -Werror on 'stable' releases
Stable releases are tagged and need to stay easy to compile in the future.
As new compiler versions introduce new warnings or catch more occurrences,
have -Werror set in tagged releases could be a bother.

We still want it on by default for all Godot developers, so it's now
conditional.

Rémi Verschelde 72ea74bcc1 SCons: Treat all warnings as errors
After an effort spanning several years, we should now be warning-free
on all major compilers, so we can set `-Werror` to ensure that we don't
introduce warnings in new code.

Disable -Werror=strict-overflow on GCC 7 though, as it seems bogus and
was fixed in 8+.

Rémi Verschelde cd4e46ee65 SCons: Format buildsystem files with psf/black
Configured for a max line length of 120 characters.

psf/black is very opinionated and purposely doesn't leave much room for
configuration. The output is mostly OK so that should be fine for us,
but some things worth noting:

- Manually wrapped strings will be reflowed, so by using a line length
  of 120 for the sake of preserving readability for our long command
  calls, it also means that some manually wrapped strings are back on
  the same line and should be manually merged again.

- Code generators using string concatenation extensively look awful,
  since black puts each operand on a single line. We need to refactor
  these generators to use more pythonic string formatting, for which
  many options are available (`%`, `format` or f-strings).

- CI checks and a pre-commit hook will be added to ensure that future
  buildsystem changes are well-formatted.

Rémi Verschelde 9d8a9ea826 assimp: Clean and document buildsystem, prepare for unbundling
- Improve the SCsub to allow unbundling and remove unnecessary code.
- Move files around to match upstream source.
- Re-sync with upstream commit 308db73d0b3c2d1870cd3e465eaa283692a4cf23
  to ensure we don't have local modifications.
- Doesn't actually build against current version 5.0.1 due to the lack
  of the new ArmaturePopulate API that Gordon authored. We'll have to
  wait for a public release with that API (5.1?) to enable unbundling.

Rémi Verschelde 2cf6ac6c50 Replace FALLTHROUGH macro by C++17 [[fallthrough]]
This attribute is now part of the standard we target so we no longer
need compiler-specific hacks.

Also enables -Wimplicit-fallthrough for Clang now that we can properly
support it. It's already on by default for GCC's -Wextra.

Fixes new warnings raised by Clang's -Wimplicit-fallthrough.

Rémi Verschelde 17a81cffb2 SCons: Ensure that MSVC gets /std:c++17 in CCFLAGS

Rémi Verschelde a4801674c5 SCons: Bump required C++ standard to C++17
As per #36436, we now need C++17's guaranteed copy elision feature to
solve ambiguities in Variant.

Core developers discussed the idea to move from C++14 to C++17 as our
minimum required C++ standard, and all agreed. Note that this doesn't
mean that Godot is going to be written in "modern C++", but we'll use
modern features where they make sense to simplify our "C with classes"
codebase. Apart from new code written recently, most of the codebase
still has to be ported to use newer features where relevant.

Proper support for C++17 means that we need recent compiler versions:

 - GCC 7+
 - Clang 6+
 - VS 2017 15.7+

Additionally, C++17's `std::shared_mutex` (conditionally used by
`vk_mem_alloc.h` when C++17 support is enabled) is only available in
macOS 10.12+, so we increase our minimum supported version.

Rémi Verschelde 342f127362 SCons: Explicitly define our C (C11) and C++ (C++14) standards
On GCC and Clang, we use C11 and C++14 with GNU extensions (`std=gnu11`
and `std=gnu++14`). Those are the defaults for current GCC and Clang,
and also match the feature sets we want to use in Godot.

On MSVC, we require C++14 support explicitly with `/std:c++14`, and
make it strict with the use of `/permissive-` (so features of C++17 or
later can't be used).

Moves the definition before querying environment flags and platform
config so that it can be overridden when necessary.

Rémi Verschelde 49fec646cb Fix compilation warnings and re-enable werror=yes on Travis
Fix -Wunused-variable, -Wunused-but-set-variable and -Wswitch warnings
raised by GCC 8 and 9.

Fix -Wunused-function, -Wunused-private-field and
-Wtautological-constant-out-of-range-compare raised by Clang.

Fix MSVC 2019 warning C4804 (unsafe use of type 'bool' in comparison
operation).

GCC -Wcpp warnings/Clang -W#warnings (`#warning`) are no longer raising
errors and will thus not abort compilation with `werror=yes`.

Treat glslang headers are system headers to avoid raising warnings.

Re-enables us to build with `werror=yes` on Linux and macOS, thus
catching warnings that would be introduced by new code.

Fixes #36132.

Rémi Verschelde 386968ea97 Remove obsolete GLES3 backend
Due to the port to Vulkan and complete redesign of the rendering backend,
the `drivers/gles3` code is no longer usable in this state and is not
planned to be ported to the new architecture.

The GLES2 backend is kept (while still disabled and non-working) as it
will eventually be ported to serve as the low-end renderer for Godot 4.0.

Some GLES3 features might be selectively ported to the updated GLES2
backend if there's a need for them, and extensions we can use for that.

So long, OpenGL driver bugs!

Rémi Verschelde 511f65214f SCons: Streamline Vulkan buildsystem + fixups
- Renamed option to `builtin_vulkan`, since that's the name of the
  library and if we were to add new components, we'd likely use that
  same option.
- Merge `vulkan_loader/SCsub` in `vulkan/SCsub`.
- Accordingly, don't use built-in Vulkan headers when not building
  against the built-in loader library.
- Drop Vulkan registry which we don't appear to need currently.
- Style and permission fixes.

Rémi Verschelde b7297fb39c SCons: Generate header with info on which modules are enabled
We already had `MODULE_*_ENABLED` defines but only in the modules
environment, and a few custom `*_ENABLED` defines in the main env
when we needed the information in core.

Now this is defined in a single header which can be included in the
files that need this information.

Rémi Verschelde c320a82213 SCons: Add 'split_libmodules' option to workaround linker issue
The new 'split_libmodules=yes' option is useful to work around linker
command line size limitations when linking a huge number of objects.
We're currently over 64k chars when linking libmodules.a on Windows
with MinGW, which triggers issues as seen in #30892.

Even on Linux, we can also reach linker command line size limitations
by adding more custom modules.

We force this option to True for MinGW on Windows, which fixes #30892.

Additional changes to lib splitting:

- Fix linking of the split module libs with interdependent symbols,
  hacking our way into LINKCOM and SHLINKCOM to set the `--start-group`
  and `--end-group` flags.
- Fix Python 3 compatibility in `methods.split_lib()`.
- Drop seemingly obsolete condition for 'msys' on 'posix'.
- Drop the unnecessary 'split_drivers' as the drivers lib is no longer
  too big since we moved all thirdparty builds to modules.

Rémi Verschelde 02913f53d3 pcre2: Use scons option to disable JIT on some platforms
Third-party platforms (e.g. console ports) need to be able to
disable JIT support in the regex module too, so it can't be
hardcoded in the module SCsub. This is cleaner this way anyway.

Fixes #19316.

Rémi Verschelde 5dae2ea777 SCons: Enable C++11 on the whole codebase
**Important:** This does not mean *yet* that C++11 features should be used
in contributions to Godot's codebase.

For now this change is done solely for feature branches working on Vulkan
support and GDScript typed instruction sets for Godot 4.0, which will both
use C++11 features and are based on the master branch.

The plan is to start porting the codebase to C++11 after Godot 3.2 is
released, following upcoming guidelines on the subset of new features that
should be used, and when/how to use them.

We will advertise clearly when C++11 contributions are open, especially
once we start a coordinated effort to port Godot's massive codebase. In the
meantime, please bear with us and good ol' C++03. :)

Andrii Doroshenko (Xrayez) 7c11a1b162 Add support for creating editor icons per module
The functionality is similar to how `doc_classes` are retrieved per module.
The build system will search for custom icons path defined per module via
`get_icons_path()` method in `config.py` or default icons path.
If such paths don't exist, only the editor's own icons will be built.

Most module icons were moved from editor/icons to respective modules.
