Implemented some basic caching to avoid unnecessary AOT compilation
of unchanged assemblies that were already compiled previously.
This reduces iOS export times considerably for subsequent builds
since many dependencies never change, such as framework assemblies
and the Godot bindings.
The AOT compiler asm output and object files are now placed in
`res://.mono/temp/obj/<CONFIG>/godot-aot-cache/` instead of a
temporary directory.
Use `System.Array.Empty<T>` to get an empty array instead of allocating
a new one every time. Since arrays are immutable there is no need to
allocate them every time.

While there are still various bugs to solve and features to implement, the C#
support as of Godot 3.4 is fairly mature and already used by a number of users
in production. Now that we default to dotnet CLI as build tool, it also seems
to be more reliable than MSBuild.
The documentation can (and does for the most part) point out some caveats that
users should be aware of, but this info dialog has outlived its intended
purpose.
(cherry picked from commit 671467b888)
Added `SystemConfiguration.framework` to the Xcode project to fix
undefined symbols errors building without the interpreter, like:
`_SCNetworkReachabilityScheduleWithRunLoop`.
Added explicit static constructors to the generated `NativeCalls`
class to avoid a `TypeInitializationException` at startup when
Godot attempts to read the static fields (like `godot_api_hash`)
from this class.
This seems to be an issue with Mono's AOT compiler and classes
with the `beforefieldinit` attribute. Not sure if it only happens
when the fields are only accessed via reflection as was our case.
Explicitly declaring the static constructor makes the C# compiler
not add the `beforefieldinit` attribute to the class.
We use `Mono.Cecil` to search for P/Invoke methods in assemblies in
order to collect symbols that we must prevent from being stripped.
We could pass the symbols as `-u` linker arguments (`-Wl,-u,symbol`)
for the native target (not for the project), but it was simpler to
generate referencing code and avoid changes to Godot's iOS exporter.
Replaced obsolete preprocessor check for simulator/device in C code.
Architecture can no longer be used to determine this with Apple Silicon.
The new code uses `TARGET_OS_SIMULATOR` from `TargetConditionals.h`.
We have some mono libs which can only be used in devide builds.
We were adding them as static libs. Previously it was only causing
warnings because missing arch for the simulator, but now this
is treated as an error.
To fix this we turn them into xcframeworks with dummy static libs
for the simulator and the actual ones for devices.
This changes the types of a big number of variables.
General rules:
- Using `uint64_t` in general. We also considered `int64_t` but eventually
settled on keeping it unsigned, which is also closer to what one would expect
with `size_t`/`off_t`.
- We only keep `int64_t` for `seek_end` (takes a negative offset from the end)
and for the `Variant` bindings, since `Variant::INT` is `int64_t`. This means
we only need to guard against passing negative values in `core_bind.cpp`.
- Using `uint32_t` integers for concepts not needing such a huge range, like
pages, blocks, etc.
In addition:
- Improve usage of integer types in some related places; namely, `DirAccess`,
core binds.
Note:
- On Windows, `_ftelli64` reports invalid values when using 32-bit MinGW with
version < 8.0. This was an upstream bug fixed in 8.0. It breaks support for
big files on 32-bit Windows builds made with that toolchain. We might add a
workaround.
Fixes#44363.

We decided to rename the upcoming 3.2.4 release to 3.3 to better reflect that
it is a significant feature release, and not a maintenance update.
The `3.2` branch was also renamed to `3.x` and will now be the development
branch for future 3.x releases (3.3, 3.4, etc.).
`Main::cleanup()` prints warnings if it finds `StringName`s still alive.
We need the `BindingsGenerator` to be destructed before calling cleanup.
(cherry picked from commit d9603b2d73)
- Based on C++11's `thread` and `thread_local`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed (except for the few cases of non-portable functions)
- Simpler for `NO_THREADS`
- Thread ids are now the same across platforms (main is 1; others follow)
- Based on C++11's `mutex`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed
- Simpler for `NO_THREADS`
- `BinaryMutex` added for special cases as the non-recursive version
- `MutexLock` now takes a reference. At this point the cases of null `Mutex`es are rare. If you ever need that, just don't use `MutexLock`.
- `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same.
