Linux: Remove use_static_cpp override on x86_32
After further testing it seems to work fine now when building binaries with GCC 5
on Ubuntu 16.04 (previously we were using GCC 9 on Ubuntu 14.04).

Follow-up to #45629.

lightmapper: Disable build if raycast module can't build
We need to propagate the hacky checks from the raycast config to the
lightmapper config, as the failure of a `can_build()` check is not notified to
other modules (which might even be checked further depending on the processing
order in SConstruct).

A more thorough fix would be to change SConstruct to do two loops on modules:
one to check `can_build()` and disable modules which can't build, then another
one to rechecked `can_build()` with the new lineup and do further config.
But there would be more risk for regressions than with this ad hoc hack.

Similar story for the `platform/x11/detect.py` change... oh my eyes :(

5f71fad6b6 Allow static linking with libatomic using clang
When using use_static_cpp we want to statically link with atomic as well
to make sure we don't incur any new runtime dependencies.

Scons doesn't quite support this so we do this little trick.

0cce213f14 Use -latomic when linking whe using clang on Linux
According to the LLVM documentation when using GNU's libstdc++ clang
will not automatically link with -latomic. This is necessary since we
merged c++11 atomics support.

This fixes linking using Clang on Linux

Dynamically load libudev.so.1 on Linux if udev=yes
This makes it possibly to run Linux binaries compiled with udev support on
Linux systems which do not provide udev (typically systemd-less distros).

If udev is missing, we fall back to parsing `/dev/input` like when compiled
without udev support (`udev=no`).

Also adding some verbose debug statements to know which method we're using
when debugging Linux joypad issues.

The libudev so wrappers were generated on Mageia 8 with libudev 246.9 using
https://github.com/hpvb/dynload-wrapper:
```
./generate-wrapper.py --include /usr/include/libudev.h --sys-include '<libudev.h>' \
  --soname libudev.so.1 --init-name libudev --omit-prefix gnu_ \
  --output-header libudev-so_wrap.h --output-implementation libudev-so_wrap.c
```

(cherry picked from commits a10c259c1d
and e26a1f807b)

Edit: Updated to version 0.2 of dynload-wrapper to fix symbols clobbering as
done in #46143.

228803e9db Dynamically load libpulse.so.0 and libasound.so.1 on Linux
By generating stubs using https://github.com/hpvb/dynload-wrapper we
can dynamically load libpulse and libasound on systems where it is available.
Both are still a build-time requirement but no longer a run-time dependency.

For maintenance purposes the wrappers should not need to be re-generated
unless we want to bump pulse or asound to an incompatible version. It is
unlikely we will want to do this any time soon.

f3c030aa47 SCons: Add production=yes option to use production defaults
This is meant for users making custom builds to match the options used on
optimized, official builds.

This enables, on the platforms which support them:
- `use_static_cpp=yes` (portable binaries for Linux and Windows)
- `use_lto=yes` (link time optimizations - note: requires a lot of RAM!)
- `debug_symbols=no` (no debug symbols, smaller binaries)

Also abort when using MSVC with `production=yes`, as:
- It cannot optimize the GDScript VM like GCC or Clang do, leading to
  significant performance drops.
- Its LTO support is unreliable, at least used to trigger crashes last
  we tried it extensively.

All options can still be overridden if specified, and the `dev=yes` option
was changed to also support overrides.

Linux: Enable udev support by default
This has been enabled for years in official binaries, and users making custom builds
may end up not enabling it unknowingly, so it's best if we default to the same as
what official builds do.

The original reason for having it opt-in was likely the addition of a dependency on
libudev, but that should be fairly ubiquitous by now.

Linux: Build with use_static_cpp=yes by default for x86_64
This enables `-static-libgcc -static-libstdc++` which help make custom Linux
builds more portable (official builds have been using this option for years).

For some obscure reason Ubuntu 18.04 i386 crashes when using the option for
i386 builds, so let's play it safe and enable for x86_64 only for now.

SCons: Add only selected platform's opts to env
Otherwise we can get situations where platform-specific opts with the same name
can override each other depending on the order at which platforms are parsed,
as was the case with `use_static_cpp` in Linux/Windows.

Fixes #44304.

This also has the added benefit that the `scons --help` output will now only
include the options which are relevant for the selected (or detected) platform.

Remove debug_symbols=full in favor of debug_symbols=yes
`debug_symbols=yes` will now behave like `debug_symbols=full` did
before. The difference in compressed file sizes is not that large,
which means there isn't much point in having two different values.

This helps make the buildsystem easier to understand.

f1cdb91f34 SCons: Remove unused DEBUG_MEMORY_ENABLED define
Its last use was removed in Godot 3.0, so it no longer makes sense to define.

long time ago pre-opensourcing when Godot had some form of Direct3D 9 support?

7bf9787921 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.

98d0bf7d7a 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.

40f4d3cf0f Add embedded PCK option to PC platforms
The basic point is as in 2.1 (appending the PCK into the executable), but this implementation also patches a dedicated section in the ELF/PE executable so that it matches the appended data perfectly.

The usage of integer types is simplified in existing code; namely, using plain `int` for small quantities.

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.

1769cbc0e2 SCons: Default to builtin libpng/freetype on Linux
The rationale for keeping those shared by default is that they're typical
dependencies found on any Linux system, and it saves compilation time and
binary size to link their dynamically.

But since official builds default to all-builtin, and Debian/Ubuntu still
don't have libpng16 (which we now require) readily available on all their
supported releases, it's simpler to bundle all the things.

This does not change the fact that those dependencies *can* be unbundled
on Linux, it's only the default option changing.

This updates our local copy to commit 5ec8339b6fc491e3f09a34a4516e82787f053fcc.
We need a recent master commit for some new features that we use in Godot

To avoid warnings generated by Bullet headers included in our own module,
we include those headers with -isystem on GCC and Clang.

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.
