Summary:
The C function `eina_hash_del_by_data` requires the same value that was
passed to the `add` function. As C# hashes store stuff through pointers
due to marshalling, this makes it hard to pass the same pointer for it.
So this functionality is implemented at C# level instead of relying on
the native function directly.
Fixes T8198
Thanks to @brunobelo and @singh.amitesh for the test case.

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:
dotnet's GC seems to be more agressive, showing some issues that usually
do not appear when running under Mono's.
This commit uses for free_cb's the same scheme we already use for
regular Eo refs, using a GC handle to keep the cleaning callback alive.

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:
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.

This commit adds the "documentation" generator, which gets the
documentation_def attribute of the given item and generates xml comments
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.
Due to this visibility change, the binbuf tests had to be changed
to add redirect calls to the native methods instead of directly
calling the DllImport'd methods.
