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:
With this commit it is now possible for a class that inherits from a C# binding
class to be instantiated from native C code. It only has to provide a
constructor that receives an `Efl.Eo.EoWrapper.ConstructingHandle` struct,
and which calls the base binding constructor passing it.
For example:
`private Type(ConstructingHandle ch) : base(ch) {}`.
Add some test files to validate the proper behavior of this feature.
Add some small fixes in generation contexts in order to properly
generate base constructors.

Summary:
Eo mixin is converted to C# interface and C# concrete class.
When the mixin's method is called, the delegate function of Eo mixin's
C# concrete class is called.
Now, the delegate function of Eo mixin's C# concrete class calls C#
method with casting to Eo mixin's C# concrete class type.
e.g. ((IClickableConcrete)ws.Target).Press(button);
If a user defined C# class implements Eo mixin's C# interface, the
implemented method cannot be called because the user defined C# class
type is not the same as Eo mixin's C# concrete class.
To resolve the above issue, the type casting code is fixed.

Summary:
This commit makes use of the `ownership,shared` and `ownership,unique`
events from Efl.Object in order to avoid the C# wrapper from being
collected while C code holds a reference to the object.
For example, creating a list of items in a for loop and attaching events to
them would fails without this commit, as the C# GC may collect the wrapper.
The basic idea is that we use a `WrapperSupervisor`, which is stored in
the Eo data storage, with a GCHandle allocated for the lifetime of the
underlying Eo object. This supervisor takes care of holding either a
weak C# reference (when in unique mode, allowing the wrapper to be GC'd)
or a hard C# reference (when in shared mode, making the wrapper
non-collectable while the Eo has extra references).
One limitation is that object graphs can leak if a shared object in the
graph - an Eo child for example - stores a hard reference to another
object in the graph as a C# field. In this example, this causes the
parent to always have a hard C# reference (from the child) as the child
is non-collectable due to the parent holding an Eo reference to it.

It fixes several bugs/leaks on the way (incorrect use of
stringshare etc.) as well as adds checking for whether there

it is now no longer possible to scan two paths which have an eo

First code line was indented differently by DocFX because of tabs,

Summary:
New option added to eolian_gen: -e <dir>
This specifies a directory to search for examples. If a file is found with the
same name as an EFL C# class (e.g. Efl.Ui.Button.cs) or as an EFL C# method or
property (e.g. Efl.IText.Text.cs, Efl.IText.SetText.cs) its full
contents will be embedded in the documentation for that class or method within
<example> and <code> tags. This is, in turn, is parsed by DocFX and shown
in Example boxes in the generated pages.
If an example file is not found, no examples are embedded for that object.
If -e is not used, no examples are embedded for any object.
New option added to meson: mono-examples-dir to point to the examples directory.
This directory is then passed to eolian_mono through -e.
Do not use it (or define it to nothing) to disable example embedding.
No performance drop has been observed because of these extra tests.
Right now examples can only be given for base classes, not for derived ones
(i.e. Efl.IText.Text but not Efl.Ui.Button.Text). This will be addressed in a

Summary:
This commit mainly fixes errors caused by deallocating resources in the garbage
collector thread. Using `ecore_main_loop_thread_safe_call_async` to queue
resource deallocation in the main thread seems to solve it.
Also, some `efl_ref` calls are added in places they were missing, mainly
objects that unref in the destructor thus taking ownership if efl_ref is not
called.
Also fix improper resource deallocation in tests that were causing it to crash,
enabling it to call Efl.All.Shutdown again. This allocation and the deallocation
process was moved from the Eo class constructor to static class methods that are
called in the test 'set up' and 'tear down' methods.
Queuing resource deallocation in the main thread make it mandatory that tests
call `Efl.App.AppMain.Iterate()` if they want to check proper resource
deallocation (like TestFunctionPointers.set_callback_inherited_called_from_c).
Extras:
Remove duplicated declaration of 'eflcustomexportsmono' in meson in order to fix
some linking problems.
Remove some unused code around deallocation functions that had to be reworked.
Object allocation is now supplied with the call site information it expects
(file name and line for _efl_add_start).

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.
