Until this commit eo did class functions as part of the vtable, which
enabled those functions to be overwritten in classes inheriting another
class. However in task T7675 we decided that this is not really good for
bindings, as most OOP languages do not support this sort of feature.
After this commit eolian realizes class function completly outside of
the vtable, the c-symbol that is the class funciton is now just directly
redirecting to a implementation, without the involvement of the vtable.
This also means a change to the syntax created by eo:
Calling before:
class_function(CLASS_A);
Calling after:
class_function();
Implementation before:
class_function(const Eo *obj, void *pd) { ... }
Implementation after:
class_function(void) { ... }
This fixes T7675.

this is another step towards enforcing free functions on every owned
type. To equip every owned type with a free function the following is
applied. Every owned ptr is assumed to be a heap pointer, with the free
function "free". Every string that is owed is converted to a mstring. a
pointer to a eo object is also assumed to be a heap pointer, and equiped
with the free function "free".

Summary:
Previously, we just converted through PtrToStructure, which didn't have
the full marshalling info converting from the internal one to the
external.
This fixes the usage of the Efl.Loop.arguments event.
Also renamed the ToExternal methods to ToManaged, to make clearer that
the output struct is the one intended to be used from the managed code.
Also fixed a minor styling in the generated code (making it easier to be
inspected).

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.
Test Plan: Run test suite.

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 interface efl_part_get should not be directly called from C, but the efl_part
wrapper should. It rely on efl_noref to properly destroy the object. Binding can
control the lifecycle of the reference the way they want by either calling the
wrapper or efl_part_get directly. It also means that the ugly ___efl_auto_unref_set
doesn't need to be exposed outside of EFL anymore.

This reverts commit 2fb5cc3ad0.
Most of this change where wrong as they didn't affect the destruction
of the object. efl_add_ref allow for manual handling of the lifecycle
of the object and make sure it is still alive during destructor. efl_add
will not allow you to access an object after invalidate also efl.parent.get
will always return NULL once the object is invalidated.

Besides the normal methods returning Futures, we now generate
a wrapper with the "Async" suffix. This wrapper returns a
Systems.Threading.Tasks.Task which can be awaited on and reflect the
status of the Future.
When an eina.Future fails with ECANCELED, TaskCanceledException is
raised in the Task. Otherwise, an efl.FutureException(eina.Error) is
raised.

Summary:
eina.Value.Empty now means that we have an zeroed (empty) eina value.
For optional values that are empty use eina.Value.OptionalEmpty.
This was required to support the empty values passed with
EINA_VALUE_EMPTY in some Ecore futures.
Also, returning an eina_value by value is not supported in eolian
for safety reasons, so we removed some tests that tried to use this
behavior.

Summary:
Due to the absence of typedef from C#, we generate thin structs with
implicit operators to allow reference the data from their typedef'd name
from C#.
The other alternatives would be always converting to the lowest base on
the alias stack (losing the meaningfulness of the typedef name) or using
the 'using' directive. The latter has the restriction that it makes an
alias visible only in the file they are declared.

Previously, class methods were implemented as regular instance methods.
This commits generates C# static methods for @class methods on the
*Concrete classes (and their childs).
Function pointers now go through the same argument marshalling pipeline
as normal functions.
This will enable interfaces like Efl.Ui.Format to work properly.
When we have an eina.Value_Native (representing an Eina_Value passed by
value) and assign it to an eina.Value (a class with an IntPtr to an
underlying Eina_Value) we copy it so the eina.Value can take ownership
and free the data normally.
A possibly better alternative would be adding an extra flag to
eina.Value (something like OwnsPointer) to check whether we should free
the struct we point to or not.
Instead of
var bg = efl.ui.Background.static_cast(myobj.Part("background"));
Now do
var bg = myobj.Background;
Also a couple helper functions were added.
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.
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.
Fix several integer binding type deduction based in its size on C.
Generation for function pointers no longer use modified argument name
which is different from the parameter name.
New generation context for structs.
bool from UnmanagedType.I1 to UnmanagedType.U1 (correct use
inside structs according to mono documentation).
byte (signed char) and int8 now is correctly represented by
sbyte in C#.
Check parameter direction in some out generators in parameter.hh.
Add efl_libs.csv to gitignore.
Make eina.Value pointer constructor public.
Add missing fields to efl.kw_event.Description struct.
Remove eina.File workaround (let struct gen handle it).
Remove is_function_ptr bool from regular_type_def and
add a typedecl_type enum to it. Also add some helper
methods for easier comparison.
Left some test cases commented for when pointer parameters
are properly working.
