* Replaces `find(...) != -1` with `contains` for `String`
* Replaces `find(...) == -1` with `!contains` for `String`
* Replaces `find(...) != -1` with `has` for containers
* Replaces `find(...) == -1` with `!has` for containers
Random-access access to `List` when iterating is `O(n^2)` (`O(n)` when
accessing a single element)
* Removed subscript operator, in favor of a more explicit `get`
* Added conversion from `Iterator` to `ConstIterator`
* Remade existing operations into other solutions when applicable
Instead of making the accessors `internal` which can break binary compat, make them `public` but hide them with EB never so they don't show up in IntelliSense.
Also, do the same for properties with the `PROPERTY_USAGE_INTERNAL` flag. These properties were not meant to be exposed to scripting, but since they've been public before all we can do now is hide them.
The Godot.NET.Sdk (for C# use) should define the property `UsingGodotNETSdk` in its [SDK.props](a07dd0d6a5/modules/mono/editor/Godot.NET.Sdk/Godot.NET.Sdk/Sdk/Sdk.props).
## Why
Defining this property allows shared build configuration (e.g. Directory.Build.targets or other imported msbuild files) to detect deterministically when they are operating within the scope of a project controlled by Godot.NET.Sdk. This enables shared build configuration that may span many different projects within a folder to have Godot.NET.Sdk-specific configuration that only applies to Godot projects.
## Why named UsingGodotNETSdk
This naming scheme is common practice in Microsoft Dotnet SDKs. For example, the property `UsingMicrosoftNETSdk` is defined by the default SDK, `UsingMicrosoftTraversalSdk` is defined by [Microsoft.Build.Traversal](363532de5b/src/Traversal/Sdk/Sdk.props (L10)), `UsingMicrosoftNoTargetsSdk` by [Microsoft.Build.NoTargets](363532de5b/src/NoTargets/Sdk/Sdk.props (L10)), and so on. The property `UsingMicrosoftNETSdk` is even used in the implementation of Godot.NET.Sdk for conditional logic of the type predicted here.
Note that these "Using*" properties are _additive_ in the sense that more than one can be defined for a given project (as SDKs can effectively be built upon other SDKs, using them as components). So, it is normal and appropriate for both `UsingMicrosoftNETSdk` and `UsingGodotNETSdk` to be simultaneously defined within the same project.
New rules:
- Do not silence CA1805 any more
- Limit where we silence CA1707, CA1711, CA1720
- Enforce severity=warning for IDE0040
- Enforce Allman style braces
- Enforce naming conventions (IDE1006 is still severity=suggestion)
Fixes:
- Fix REFL045, CS1572, CS1573
- Suppress CS0618 when generating `InvokeGodotClassMethod`
- Fix indent when generating GD_constants.cs
- Temporarily silence CS1734 in generated code
- Fix a lot of naming rule violations
Misc.:
- Remove ReSharper comments for RedundantNameQualifier
- Remove suppression attributes for RedundantNameQualifier
- Remove severity=warnings for CA1716, CA1304 (already included in the level of analysis we run)
- Add tests for the following diagnostics: GD0101, GD0102, GD0103, GD0104, GD0105, GD0106, GD0107.
- Fix GD0101 not being reported any more (was filtering static classes before reporting).
- Fix GD0107 not preventing `Node` members from being exported from not-`Node` types.
