Add a new function in the Eo API in order to provide more options on object
instantiation for binding creators.
For the Eo lib to be able to construct objects that inherit from bindings in
many languages we should provide a way for bindings to call different kinds of
constructors, in a way that simply overriding the `efl_constructor` method is
not enough.
We need a way to differentiate at construction time if the Eo is being
constructed from C or from the binding, because if it is the
former we need too call the inherited object constructor from C and instantiate
a new object, and if it is the later we need to avoid instantiating a
new object because we are already in the middle of the process of creating
a new one.
`efl_constructor` alone does not provide any way of distinguishing between
those situations, so, being able to pass additional information for
efl_add_start (like a custom constructor pointer) is necessary to make the
right distinction.

Some user code may want to track an object ownership in regard to whether it is
kept by just one owner or shared between many owners.
This is specially true for code provided by bindings to other programming
languages, where different kinds of resource management may take place.
The event `ownership,unique` is triggered whenever the object refcount goes
from two to one, as a signal that it has just one owner from now on.
The event `ownership,shared` is triggered whenever the object refcount goes
from one to two, as a signal that it has multiple owners from now on.
It will not trigger when further increasing the refcount to any value beyond
two.
We also add benchmarks for sharing (i.e. increasing the refcount) and them
unsharing objects, in order to evaluate the performance impact of this patch.

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 check caused a leaked reference.
Eo objects are having two reference counters a internal and external
one. The external one can be manipulated via efl_ref / efl_unref. The
internal one can be manipulated via _efl_ref _efl_unref.
The external reference counter is keeping a internal reference by the
time the external counter is > 0. When the external counter reaches ==
0 this internal reference is given up with the _efl_unref call in
eo.c:1928.
However, checking unref_compensate in the block in line 1950 leads that
to the leak that this internal reference is not given up at the pointer
user_refcount reaches exactly 0. This check also does not prevent
anything, the object is kept alive anywayys as the efl_unref method
keeps its private internal reference.
This lead to leaks in efl_device_* classes, parts have not been
destructed correctly.
Differential Revision: https://phab.enlightenment.org/D6252
Summary:
this function calls _efl_ref in the beginning, so _efl_unref them in the
end. This fixes bugs where wrong evas_object_del is called to often,

0.
