Summary:
Both C strings and eina stringshares are bound as regular strings in EFL#, as
working directly with these types would demand unnecessary hassle from the user
viewpoint.
But for eina containers this distinction is important, and since C# generics
do not provide a convenient way of dealing with the same type requiring a
different management based on some other condition (at least not without
compromising the usability for other types), we added a simple `System.String`
wrapper named `Eina.Stringshare` that works as a placeholder for signaling
this distinction.
Working with this class should be transparent in most use cases because it
converts to and from `System.String` implicitly.
It also implements equality/inequality methods for easier comparison with
strings and other stringshare objects.
Add new methods and a new container element trait for dealing specifically
with `Eina_Stringshare` elements.
Adapt eolian_mono to identify and generate the proper placeholder in methods
that require stringshare containers.
Remove some direct uses of DllImport-ed functions in favor of more flexible
manual binding methods.
Move `Eina.Stringshare` DllImport directives to a static class named
`NativeMethods`, in accordance with the code design warning CA1060.
Also add a TODO comment to move all other DllImport directives to this class.
Change parameter of the method `Efl.Csharp.Application.OnInitialize` from
`Eina.Array<System.String>` to `string[]`.
This will make this API more similar with the default C# way of receiving
command line arguments.
Add tests for containers storing stringshare elements.

Summary:
Abstract Eo classes are now proper C# abstract classes.
As a side effect, returning Eo instances from native code was reworked
to return instances of their actual Eo classes instead of previous
behavior of returning a generic Efl.Object and using static_cast.
Instead of `var window = Efl.Ui.Win.static_cast(widget.GetParent());`
Use `var window = widget.GetParent() as Efl.Ui.Win;`
Another side effect was that `efl_constructor` was removed from the list
of supported `Efl.Object` overrides. It is invoked inside
`efl_add_internal_start`, before the bindings makes the association of
the newly created EoId with the C# instance that created it, making the
managed delegate meaningless. C# users then can use regular C#
constructors to initialize fields.
Also changed to set the private data of C#-inherited classes before the
call to constructing methods (aka constructor parameters) so C# classes
can override them correctly.

Summary:
In order to work around an issue with Efl.App, which is stable but
inherits from Efl.Core.Command_Line, @beta interfaces/mixins in the
inheritance chain are simply skipped.
Also changed the class used int test for inheritance from C#
Efl.Loop is stable but internally it uses a @beta class as argument to
its Register() method in the constructor. When instantiating a
user-defined C# subclass, the binding calls the C# override in the
NativeInherit class and the marshalling fails as no code is generated
for the beta class.
Also moved Efl.Part test to a beta class. Efl.Part is still beta.
Regarding parts, they are skipped if its class is @beta too.
Also rejected all elm_* files in elm public eo files. They should get
back in as they are converted to Efl.Ui.* api. An exception is
elm_interface_scrollable.eo, as efl_ui_panel depends on it.

Summary:
This commits adds dotnet as a supported C# platform for EFL# bindings.
Due to differences between Mono and Dotnet regarding DllImport, the
bindings now are using an imperative approach to load the function
pointers through the NativeModule and FunctionWrapper classes. These
classes handle the dlopen/LoadLibrary and dlsym/GetProcAddress calls.
Also, the previous caching of non-owned strings returned to native code
was removed until further memory checks.
We also had to create workaround for bool and chars in Structs for C#
marshaling. Going through System.Byte instead and Marshaling manually
to their respective types.
In order to actually build efl_mono.dll with dotnet right now,
issue #4782 from Meson should be fixed to make it properly detect and
used the Dotnet compiler. Also use "-Ddotnet=true" when running meson.

Summary:
As discussed in T7204:
- Eo Interfaces/mixins -> C# Interfaces with concrete class
implementations
- Eo Regular/Abstracts -> Proper C# classes
- Added some new generators and helper methods.
- Refactored the class generator, splitting into helper methods
Eo handles now are stored only in the "root" class in any given
inheritance tree (generally, Efl.Object), and accessible to each child.
Methods also are defined in a single place instead of repeatedly
generated in everyfile, reducing the size of the generated .dll from
30MB to around 4.5MB.
Mixins are generated as C# interfaces but any regular class it inherits
from is lost, as we can't have interfaces inheriting from regular
classes. This will be dealt with in a later commit.
Summary of API Changes:
- Merged Inherit/Concrete classes. (These suffixes disappear from
regular classes).
- Interface still have implementations with 'Concrete' suffix for when
they are returned from methods.
- Removed 'I' from interface names.
- Removed interfaces for regular/abstract Eo classes.
- Concrete classes for interfaces/mixins hold the event argument struct.
- Removed '_' from classes, enums, structs, etc, as indicated in C#
naming conventions.
- Namespaces are now Camel.Cased.
- Renamed IWrapper's raw_handle/raw_klass to NativeHandle/NativeClass
Also renamed the test classes as after the namespace change, the
test namespace Test can conflict with the helper Test namespace.
(And use more meaningful names than Test.Testing...)
Also Fixes T7336 by removing a deprecated example and adding
efl_loop_timer_example to build system.
Fixes T7451 by hiding the class_get DllImports and renaming the IWrapper
fields. The native handlers are used in the manual binding.
Still need to work:
- As there are still some events names clashing (e.g. Efl.Ui.Bg with "resize"
from Efl.Gfx.Entity and Efl.Gfx.Image), Events are currently declared on
the interface and implemented "namespaced" in the classes,
requiring the cast to the interface to access the event.
- The Mixin Conundrum. Mixin inheritance will be dealt in a future
commit.

Summary:
The efl.Event struct has a class field that gets generated normally but
can be problematic when marshalling the struct back from C to C#. The
compilation works fine but when C# runtime tries to marshall the C data
(e.g. accessing the Event.Info field), it becomes erratic, either
complaining about missing references to object or even segfault.
This commit changes the event handling code to use the
"Event_StructInternal" struct as is already done when receiving structs
from C code.
In order to work with other assemblies, the _StructInternal fields were
made publit too.
Fixes the events tests and the text editor app.
Test Plan: make check and run the text editor app in examples repo.

In general, ptr(struct) parameters behavior depends whether the
parameter has the @owned modifier or not.
If there is no @owned parameter (meaning no transfer of ownership
happens) and it is a "complex" struct, with reference type fields
(like strings), the struct is converted to the respective
<Struct>Internal struct and passed with "ref" to the DllImport'd
function. For @in parameters, after the function it returns, this
intermediate struct is converted to the public struct type and
assigned to the original parameter, updating it to the external
world.
When we have ownership transfers, the structure is copied to unmanaged
memory and given to the callee. We can't send managed memory directly as
the callee may try to free it. On the managed side, the original struct
is left to be garbage collected normally.
Summary:
C# does not have a literal form for structs (like C++'s {} aggregate
initialization). Before this commit the user would need to explicitly
instantiate a struct and assign the required values to it, like:
eina.Size2D size;
size.W = width;
size.H = height;
widget.SetSize(size);
As a workaround, this commit generates helper constructor with
parameters corresponding to the struct fields in the order they are
declared. These parameters have default values if one does not want to
explicitly initialize all fields directly. With these constructs, the
above code could be translated to:
widget.SetSize(new eina.Size2D(width, height));
It should be noted that the constructed struct will live on the managed
memory (GC) instead of the stack.

This commit adds the "documentation" generator, which gets the

to be exported by MCS.
For items requiring some customization of the generated comments (e.g.
functions and its parameters), the helpers to generate the preamble
(summary), body (paragraphs) and epilogue (currently just the @since
tag) were added.
Currently we do not support converting Eolian references into xmldoc
references.
As we explicitly generate Get/Set methods for properties, for now the
generator tries to get the get/set specific documentation first. If it
is not present, fallback to the common docs.
Later this could be changed to generate the common one as paragraphs of
the Get/Set.
Also some generated code like the wrappers for calling C# methods
from C can be private. This will cleanup the introspection results
and warnings when generating documentation.

to add redirect calls to the native methods instead of directly
calling the DllImport'd methods.
