Rémi Verschelde f940e5e000 CI: Install master version of psf/black
Until https://github.com/psf/black/pull/1328 makes it in a stable release,
we have to use the latest from Git.

Apply new style fixes done by latest black.

Andrii Doroshenko (Xrayez) 42bee75e86 SCons: Dump construction environment to a file
A new `methods.dump(env)` is added to dump the construction environment
used by SCons to build Godot to a `.scons_env.json`. The file can be used
for debugging purposes and any external tool.

Rémi Verschelde 7c74312217 SCons: Validate dependencies for linked multimedia modules
This is still a bit hacky and eventually we should rework the way we handle
optional dependencies (especially with regard to builtin/system libs), but
it's a simple first step.

Fixes #39219.

Andrii Doroshenko (Xrayez) 17938fd547 SCons: use `OrderedDict` to ensure insertion order of modules
The insertion order for dictionaries is only a language feature for
Python 3.6/3.7+ implementations, and not prior to that.

This ensures that the engine won't be rebuilt if the order of detected
modules changes in any way, as the `OrderedDict` should guarantee
inerstion order.

SCons: Move build progress related logic out of main SConstruct

Andrii Doroshenko (Xrayez) 12389b3736 Do not rely on the existence of `config.py` while detecting modules
The existence of `SCsub` is checked instead. This file is required for
all modules, and prevents the build system to leave modules without
`config.py` undetected, leading to silently ignoring the module during
compilation.

Andrii Doroshenko (Xrayez) a96f0e98d7 Add `custom_modules` build option to compile external user modules
This patch adds ability to include external, user-defined C++ modules
to be compiled as part of Godot via `custom_modules` build option
which can be passed to `scons`.

```
scons platform=x11 tools=yes custom_modules="../project/modules"
```

Features:

- detects all available modules under `custom_modules` directory the
same way as it does for built-in modules (not recursive);
- works with both relative and absolute paths on the filesystem;
- multiple search paths can be specified as a comma-separated list.

Module custom documentation and editor icons collection and generation
process is adapted to work with absolute paths needed by such modules.

Also fixed doctool bug mixing absolute and relative paths respectively.

Implementation details:

- `env.module_list` is a dictionary now, which holds both module name as
  key and either a relative or absolute path to a module as a value.
- `methods.detect_modules` is run twice: once for built-in modules, and
  second for external modules, all combined later.
- `methods.detect_modules` was not doing what it says on the tin. It is
  split into `detect_modules` which collects a list of available modules
  and `write_modules` which generates `register_types` sources for each.
- whether a module is built-in or external is distinguished by relative
  or absolute paths respectively. `custom_modules` scons converter
  ensures that the path is absolute even if relative path is supplied,
  including expanding user paths and symbolic links.
- treats the parent directory as if it was Godot's base directory, so
  that there's no need to change include paths in cases where custom
  modules are included as dependencies in other modules.

Andrii Doroshenko (Xrayez) d753a7630a Moved to methods.py as a `show_progress` method.
Some required changes are made:
- locally imported SCons-specific packages within the method;
- `global` variables converted to `nonlocal` (used in nested functions).

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 df7ecfc4a7 SCons: Expand env variables to check compiler version
Scons' `Environment.subst()` does that, and was already used in the
other place where we query an env variable (`env["LINK"]` in x11 code).

Fixes `3.2` iOS build after cherry-pick of #36559 (previously it only
ran for GCC code, not iOS's Clang), and the same issue would likely
affect `master` if iOS builds were enabled right now.

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.

Joost Heitbrink dc61323b2c PCK: Set VERSION_PATCH in header, factor out header magic
Unify pack file version and magic to avoid hardcoded literals.

`version.py` now always includes `patch` even for the first release in
a new stable branch (e.g. 3.2). The public name stays without the patch
number, but `Engine.get_version_info()` already included `patch == 0`,
and we can remove some extra handling of undefined `VERSION_PATCH` this
way.

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.

santouits 21297a533e fix getting correct mingw-w64 version
When checking mingw-w64 version, at least on debian, the regex being used returned 86 because the name of the binary in debian starts with x86_64-w64 so we use the dumpversion option that gcc has. This fixes not compiling because gcc versions < 7 don't have some checks like shadow-local

warning about duplicates in add_source_files(), and fixed
default_controller_mappings.gen.cpp being included twice after first build
due to *.cpp globbing.

Part of #30270.

Rémi Verschelde b0d41847ed SCons: Use CPPDEFINES instead of CPPFLAGS for pre-processor defines
It's the recommended way to set those, and is more portable
(automatically prepends -D for GCC/Clang and /D for MSVC).

We still use CPPFLAGS for some pre-processor flags which are not
defines.

Rémi Verschelde c2a669a9f0 SCons: Review uses of CCFLAGS, CXXFLAGS and CPPFLAGS
Many contributors (me included) did not fully understand what CCFLAGS,
CXXFLAGS and CPPFLAGS refer to exactly, and were thus not using them
in the way they are intended to be.

As per the SCons manual: https://www.scons.org/doc/HTML/scons-user/apa.html

- CCFLAGS: General options that are passed to the C and C++ compilers.
- CFLAGS: General options that are passed to the C compiler (C only;
  not C++).
- CXXFLAGS: General options that are passed to the C++ compiler. By
  default, this includes the value of $CCFLAGS, so that setting
  $CCFLAGS affects both C and C++ compilation.
- CPPFLAGS: User-specified C preprocessor options. These will be
  included in any command that uses the C preprocessor, including not
  just compilation of C and C++ source files [...], but also [...]
  Fortran [...] and [...] assembly language source file[s].

TL;DR: Compiler options go to CCFLAGS, unless they must be restricted
to either C (CFLAGS) or C++ (CXXFLAGS). Preprocessor defines go to
CPPFLAGS.
