* WIP: Benchmarks
* Initial refactor of binding infrastructure.
- `ExpressionObserver` has been removed and its functionality merged with `BindingExpression`
- `BindingExpression` handles all types of `BindingMode` itself; doesn't require `BindingOperations.Apply` to set up a separate observable for `TwoWay/`OneWayToSource` bindings
- This allows us to fix some long-standing issues with `OneWayToSource` bindings
- Expression nodes have been refactored
- No longer split between `Avalonia.Base` and `Avalonia.Markup`
- Categorize them according to whether they use reflection or not
A few tests are failing around binding warnings: this is because the next step here is to fix binding warnings.
* Make default binding Source = UnsetProperty.
Null is a theoretically valid value for `Source`; setting it to null shouldn't mean "use the data context".
* Move logging to BindingExpression.
As `BindingExpression` now has enough information to decide when it's appropriate to log an error/warning or not.
Fixes#5762Fixes#9422
* Add compatibility hack for older compiled bindings.
Previously, `CompiledBindingPathBuilder` didn't have a `TemplatedParent` method and instead the XAML compiler rewrite templated parent bindings to be a `$self.TemplateParent` property binding. resulting in extraneous logs.
Add a constructor with an `apiVersion` to `CompiledBindingPathBuilder` which will be used by newer versions of the XAML compiler, and if a usage is detected using an `apiVersion` of 0, then upgrade `$self.TemplatedParent` to use a `TemplatedParentPathElement`.
* Log errors from property accessors.
* Don't log errors for named control bindings...
...on elements which aren't yet rooted.
* Log errors for failed conversions.
* Use consistent wording for binding warnings.
"Could not convert" instead of "Cannot convert".
* Log warnings for converter exceptions.
* Don't convert new TargetTypeConverters each time.
* Added failing test for implicit conversion.
* Support cast operators in compiled bindings.
A bit of a hack as we'd ideally not be using reflection when using compiled bindings.
* This shouldn't be a public API.
Should only be used for tests.
* Make enum/int conversion work.
* Check for SetValue equality after conversion.
And also use "identity equals" where value types and strings use `object.Equals` and reference types use `object.ReferenceEquals`.
* Added ConverterCulture back to bindings.
* Fix merge error.
Removed deleted files from csproj that were re-added due to indentation changes.
* Use BindingExpression directly in ValueStoe.
* Introduce BindingExpressionBase.
And `UntypedBindingExpressionBase`.
* Make TemplateBinding a BindingExpression.
* Make DynamicResource use a BindingExpression.
* WIP: Start exposing a BindingExpression API.
* Finish exposing a BindingExpression API.
* Fix OneTimeBinding.
* Remove unneeded classes/methods.
* Don't call obsolete API.
* Make BindingExpressionBase the public API.
This matches WPF's API.
* Added BindingExpressionBase.UpdateTarget.
* Initial implementation of UpdateSourceTrigger.
* Don't use weak references for values.
If they're boxed values, they can get collected.
* No need for virtual/generic methods here now.
* Reintroduce support for binding anchors.
Turns out these were needed by animations, just our animation system has no unit tests so I missed that fact earlier. Add a basic animation unit test that fails without anchor support, and add binding anchors back in. Currently a private API as I suspect this feature shouldn't be needed outside the framework.
* Include new property in clone.
And add real-life example of `UpdateSourceTrigger=LostFocus` to BindingDemo.
* Fix merge error.
* Updated BindingExpression tests.
- Make them run for both compiled and reflection bindings (found a bunch of tests that fail with compiled bindings)
- Make them not depend on converting the `BindingExpression` to an observable and instead test the end result of the binding on an `AvaloniaObject`
* Fix compiled binding indexer tests.
* Use data validation plugins in PropertyAccessorNode.
Added a warning suppression for now: we may need a separate `DataValidators` list for AOT-friendly plugins.
* Don't separate plugins by reflection.
`DataAnnotationsValidationPlugin` is public and so it can't be moved. No point in moving the others if this one will be in the wrong place.
* Remove unneeded methods.
* Make reflection binding tests use a string.
Convert the `System.Linq.Expression` to a string and then use this, as reflection bindings will always be instanced with a string path.
* Added TODO12 plan for IBinding2.
* Use more specific exception.
* Fix nits from code review.
* Make expression nodes sealed where possible.
* Unsubscribe on Stop, don't re-subscribe.
D'oh.
* Tweak ExpressionNode lists.
Saves a few K in benchmarks and it's a cleaner API.
* Add a pooled option in BindingExpressionGrammar.
Micro-optimization.
* Avoid allocations when enumerating binding plugins.
* Add IBinding2 support to observable bind overloads.
In the case of `TemplateBinding`, the `IObservable<object?>` bind overload is selected by C#. Add an explicit check for an `IBinding2` here to use the more performant code-path.
* Remove disposed binding from ImmediateBindingFrame.
* Added TemplateBinding benchmarks.
* Remove duplicate items.
Seems to have been caused by a merge error.
* Fix exception when closing color picker.
And add tests.
* Don't skip converter when binding to self.
* Don't pass UnsetValue to converters.
This follows WPF behavior.
* Log element name if present.
More useful than just logging the control hash code.
* Respect binding priority.
* Throw on mismatched binding priorities.
We don't want to respect the binding priority in this case as it breaks `TemplateBindings` when the default `LocalValue` priority is passed. Instead make sure that the priority parameter matches that of the expression.
This reverts commit a72765d705.
* Convert to target type in TemplateBinding.
* Short-circuit target type conversion for same types.
They implicitly create a new `MediaContext` via the following stacktrack, which can break subsequent tests:

- animation/layout/render cycle is now managed from a central location
- animations are now throttled if animation/layout/render pass takes longer than a frame which previously caused a soft-freeze with input not being processed
- the public API is trimmed to make sure that we can make other planned changes during the 11.x support cycle
"Changelog":
- IClock is hidden and is planned to be replaced later
- Animator classes are hidden and are planned to be refactored later
- IAnimation members are hidden, it's supposed to be a marker interface for Style.Animations collection now, to start animations manually use Animation.RunAsync
- Sealed several classes in Avalonia.Animation namespace
- Spring class is removed from the public API (it wasn't possible to use it directly in a meaningful way anyway)
- Sealed brushes, transforms, effects and drawings
- Removed separate dispatcher priorities for Layout and Composition, everything now happens from a central place with Render priority (same as WPF)
- - some private "hook" priorities are added for now, those will be removed later
- IRenderLoop is hidden and removed from locator
- IRenderer is hidden (the plan is to remove that concept later)
- - Renderer.Start/Stop exposed as StartRendering/StopRendering on the toplevel (will be on a CompositionTarget/PresentationSource-like type later)
- - Renderer.Diagnistics exposed as RendererDiagnostics (same)
- - Renderer is no longer created by the platform code and is created by TopLevel itself
- - From the user-code hit-testing should be done by VisualExtensions.GetVisual(s)At, which has the same features
- - For unit tests a separate IHitTester interface is added which can be changed for a particular toplevel
- ILayoutManager is hidden
- - LayoutManager.ExecuteLayoutPass() exposed as TopLevel.UpdateLayout()
- Custom animators now have a separate base class that only deals with interpolation
Minor improvements:
- Compositor has a mode that doesn't use DispatcherTimers, useful for unit tests
- Introduced ScopedTestBase that auto-resets the locator when test is finished
* Merge core libraries.
Everything below `Avalonia.Controls` into `Avalonia.Base`.
* Move new files to correct place.
* Removed unused dirs/projects,
* Removed outdated references from theme assemblies.
* Merge unit tests to match new assembly layout.
* Fixup test namespaces.
* Make directory match namespace.
* Move files to match namespace.
* Move files to match namespace.
* Fix up incorrect namespace.
`Avalonia.Visuals.Media.Imaging` -> `Avalonia.Media.Imaging`.
* Fix resource URL.
* Removed outdated dependencies.
* Added missing project reference.
* Update test namespaces.
* Fix merge error.
* Fix merge errors.
* Fix bad merge in WindowsInteropTest.csproj.
* Fix up merge errors in csprojs.
* Remove merged tests from nuke.
* Fix up namespace.
* Fix compile error.
* Fix failing tests.
Now that more unit tests are present in Avalonia.Base.UnitTests, general `AvaloniaObject` properties are getting registered. Ignore those.

If a child that already has a parent was added as a visual child of
another control and the exception caught, the control would still be
present in the VisualChildren collection.
Some tests still failing as controls are only registered with name scope
when attached to a rooted visual tree. Need to work around this by
explicitly registering controls when applying template.
