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 73df0d47ff csharp: encapsulate some internal code of EoWrapper
Summary:
Encapsulate some parts of EoWrapper making them less accessible to lib users.
This can avoid unnecessary and risky usage of code that is only intended for
internal usage.

`inherited` field was made private and renamed to `generated`. Now its value
can only be obtained through the `IsGeneratedBindingClass` property.

`handle` field was made private.

`eventLock` was renamed to `eflBindingEventLock`

`ConstructingHandle` property set was made private.

Constructors that are used to create new EFL# managed objects by wrapping a
preexisting eo handle now receive a specific struct wrapping the handle pointer.
This can avoid faulty interactions with the Reflection engine used only for
generated classes that implement this constructor.

Vitor Sousa fcf5f1d2e2 csharp: Refactor wrapper lifetime.
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.

Vitor Sousa 7c28762f15 efl-csharp: fix crash when events trigger after C# object `Dispose`
Summary:
Rework general event handling to check individually each event call, if the
object is not alive then the event will not be propagated.
WeakReferences (and lambdas capturing those WeakRefs) are used to ensure this.

Dispose methods in object now take care of checking if efl libraries are still
initialized and thread-safely unregister each event before performing an
efl_unref on the Eo object.

Event handling in C# is now centered around a single dictionary inside the
object: `EoEvents`.

C# event triggers now properly trigger events on C too.

Standardize C# event-triggering methods names (remove underscores).

Some diminished use of static memory due events no longer requiring static key
objects to be registered/unregistered.

Some fixing of white space generation for generated events.

Lauro Moura 1e22db1150 csharp: Make classes abstract and rework casting
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.

Lauro Moura f29ceef500 efl-csharp: Respect beta for classes and other stuff.
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.

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.

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

complaining about missing references to object or even segfault.

from C code.

In order to work with other assemblies, the _StructInternal fields were
made publit too.
