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:
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.

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.

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,

Summary:
After the new API, the virtual wrapper classes (*NativeInherit) just
declared the wrappers for the current class. But as they didn't have any
inheritance information, reimplementing methods from a parent Eo class
wouldn't work. (e.g. Efl.Ui.Button reimplementing Efl.Object
FinalizeAdd).
This commit changes these NativeInherit classes to mimic the inheritance
chain of their regular/abstract counterparts, reusing the virtual
wrapper implementations.
In order to access the correct Eo class created, the methods on it were
changed from static to instance methods. The instance will be held as a
class member of the regular/abstract API class to keep the delegates
alive and allow getting C Function pointers from them.
The class_initializer method was also split in two. The method
collecting the wrapper delegates was extracted in order to call the
parent ones.
Also avoid exception in cached strings queries as TryGetValue requires
non-null keys.

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.

For items requiring some customization of the generated comments (e.g.

Currently we do not support converting Eolian references into xmldoc

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.
