As in the previous commit explained, we want to get rid of class
functions in eo, and make them just c functions right away.
This commit removes the class parameter from the eo_class_function_set
call, and adjusts the tests to not depend on class functions anymore.
Class functions are now not tested anymore, tests that used them as a
way to test *things* are adjusted to test them now with object
functions, tests that just tested the working of class functions are
dropped.
This fixes T7675.

this adds support in eo to generate a reflection API. To get the actaul
reflection to the klass, the API efl_class_reflection_table_set needs to
be called, the table in the end can be generated by eolian. Reflection
API is inherited by the extended class. This means, if you have two
reflection tables, first, the most upperst is called, then the next
lower one is called.
For now this API accepts NULL setter or getter, and will ignore them
silently when they are called.

this enables an app or a platform to add an override for a given class,
then return a different object when that class is created. the benefit is

Summary:
In the case when you have multiple future in flight related to one object, you
couldn't use the previous version of efl_future_then. Now all function calls
take a void* pointer that allow multiple future to have their private data
request data accessible in all the callback.
This should not break released API as Eo.h is not released yet and so
was efl_future_Eina_FutureXXX_then.

Summary:
Check if the Eo to be replaced is NULL before calling efl_unref.
The documentation implies that the replaced object can be NULL, so this
check avoids unnecessary function calls and warning logs.
Add an EINA_SAFETY check in order to properly print an error message
when the function is used with an NULL storage pointer.
The documentation specifies that the first parameter can not be NULL.
So printing an error message should be better than silently returning.
Add a boolean return to the function that signalizes if the content of
the storage was changed. It is NOT an success/error flag, it is just a
simple helper to quickly test for a change in content.
This feature was inspired by eina_stringshare_replace that is used in
similar ways around the code.
Change the documentation to match the changes and to be more specific
about what is expected and how the arguments are treated.

Allowing override of efl_del allow for messing with object life cycle which can create
problem for binding where an object was expected to be invalidated, but isn't really.
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.

These events have been removed from efl_object.eo. Bindings can
still use the EFL_EVENT_CALLBACK_ADD and EFL_EVENT_CALLBACK_DEL
events from C, but they won't be available to the bound language.
The rationale is that bound languages probably will have their
own way to handle callbacks and C function pointers will mean
very little to them. For example, the binding code could route
the native callback through a dispatcher so the received
function ptr would always be that of the dispatcher method.
Closes D6179.
Summary:
This is just a wrapper around efl_add_ref() with a NULL parent.
It only simplifies a bit object creation when no parent is desired, but it
simplifies a lot the explanation of the refcounting concepts (and tutorials).

so the MAIN loop is actually an efl.app object. which inherits from
efl.loop. the idea is that other loops in threads will not be efl.app
objects. thread on the creator side return an efl.thread object.
inside the thread, like the mainloop, there is now an efl.appthread
object that is for all non-main-loop threads.
every thread (main loop or child) when it spawns a thread is the
parent. there are i/o pipes from parnet to child and back. so parents
are generally expected to, if they want to talk to child thread, so
use the efl.io interfaces on efl.thread, and the main loop's elf.app
class allows you to talk to stdio back to the parent process like the
efl.appthread does the same using the efl.io interfaces to talk to its
parent app or appthread. it's symmetrical

eo: speed-up generated calls by removing call cache
The call cache needed to by thread-local, to avoid concurrency issues.
Problem with TLS is that is adds an extra overhead, which appears to be
greater than the optimization the cache provides.
Op is naturally atomic, because it is an unsigned integer. As such, it
cannot be tempered with while another thread is reading it. When
entering the generated function, the first operation done is reading
'op'. If we have concurrency, we will have access sequences returning
either EFL_NOOP or a VALID op, because 'op' is not set until the very
end of the function, when everything has been computed. As such, we now
use the 'op' atomic integer to instore a lock-free/wait-free mechanism,
which allows to drop the TLS nature of the cache, speeding up the access
to the cache, and therefore making functions execute faster.
We don't test anymore the generation count. This can be put as a
limitation. If means that if you call efl_object_shutdown() and
re-initialize it later with different data, opcodes will be invalid.
I am not sure there is any usecase for this to ever happen.
We could move all the caches in a dedicated section, that can be
overwritten after a call to efl_object_shutdown(), but I am not sure it
will be very portable.

This API is meant to be used by parts only, and by bindings dealing with
part objects. This patch fixes make check which got broken in the after
the previous one (cxx).
there can be cases where the call to such a function is never going to
be directed to the actual implementation. In those cases the FallackCall
will be called.
It's not enough to check the init generation count, if the cache data is
not reset properly.
This patch adds safety in two ways:
1. Actually reset the op call cache when we detect a new generation
2. Verify that we don't return NULL function pointer
The 1st point is absolutely necessary, 2nd is optional (extra cost of
one if()).
@fix
This commit adds the EO support for the new future infra.
From now on there's no need to efl_future_link()/efl_future_unlink()
object and futures since the new API already handles that internally.
This will include the following information, by default:
- class name
- whether the class is an override
- eo id (pointer)
- refcount
- name if one was set (Efl.Object property)
This also supports classes, which is why it's an EAPI in eo.c
and not only a method of Efl.Object
This can be overriden by subclasses using the empty method
Efl.Object.debug_name_override.get
If the function is overriden, then the returned string is used
as is and so it is left to the subclass to include all the
necessary information (as above). This can easily be achieved
by calling efl_debug_name_get(efl_super()) and then concatenating
the strings.
Think of this function as something like Java's toString(), but
only for debugging (i.e. a string class should not just return
its string value).
@feature
This allows two things:
- adding new override functions on an object that already has
overrides
- resetting a specific function (or list of functions) to the
parent class implementation by passing NULL as implementation
