Lauro Moura 29d24aa409 csharp: Add marshal support for Eina.ValueType
Summary:
It uses a custom marshaler and a helper boxing class to convert between
the managed enum values and the native Eina_Value_Type pointers.

To be used by future MVVM machinery.

Vitor Sousa 253e18159b eolian_mono: parse `binbuf` and `event` keywords, also re-enable binbuf tests
Summary:
Parse `binbuf` and `event` type names and generate the proper binding type.

In 288f645e3c tests for `Eina.Binbuf` were disabled in order to avoid the
usage of deprecated notations in eolian.

Since the new `binbuf` keyword works as a substitute for the old notation
`ptr(Eina.Binbuf)`, tests were updated and re-enabled using the new notation.

Test Plan: `meson test`

Vitor Sousa b1e44484a5 cxx: remove compilation warnings in C++ code, from both gcc and clang
Summary:
Remove almost all the compilation warnings from C++ code. Only explicit
warnings using the `#warning` preprocessor directive remain.

Some warnings had to be suppressed with `#pragma` directives because the
behavior they were warning about is intended in some specific places.
Code comments were added in such situations.

Added a generator that creates `#pragma` directives in order to suppress
warnings in all generated C++ headers.
Currently `-Wignored-qualifiers` is the only warning category being suppressed.
The innocuous const qualifiers that it points are inoffensive and have
no effect in compilation at all.
They are also hard to track in generation since they can emerge from different
types in many places.

To ease the generation of the warning suppressors an utility constructor was
added to `efl::eolian::grammar::attributes::unused_type`.

Add constructors to `eolian_mono::class_context` to default initialize its
internal string and avoid field initialization warnings.

Test Plan: `meson test`

Vitor Sousa 4496022a3c csharp: fix Eina_Stringshare support in containers for manual and generated API
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.

Vitor Sousa b530b871bc eolian_csharp: hide struct native representation inside the managed struct
Summary:
Rework the struct binding generator to declare the native struct nested inside
the managed one.
This way native structs are less likely to cause confusion; for example
with an IDE that supports automatic completion.

Get rid of struct conversion class methods in favor of using (the already
generated) implicit conversion operators.

Lauro Moura a4ae92d8dd efl-csharp: Remove spaces from type strings in generator.
Summary:
Previously, the type_impl and marshall_type_impl generators relied on a
type mismatch in the match table to fallback to the else branch in the
match check to actually print the type string. This was achieved by
adding the " " prefix to the type.

This commit changes this behavior to invoke a proper visitor just to
print and makes both generators return trimmed type strings.

This will help conforming to the C# coding conventions.

Felipe Magno de Almeida f392c5a436 efl-mono: Add support for dotnet core
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.

Lauro Moura 3623753c1d csharp: Change to new class API.
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.

Lauro Moura 2705ea8531 csharp: Fix support for ptr(structs)
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.
