Summary:
Here is an additional optmization patch for removing
unnecessary updation of path,
For instance, let's assume this scenario:
If one vg object has 20 path nodes(shapes),
and every single nodes would have 50 path changes.
(like, append_cubic, append_rect, append_xxx ...);
There would 1000 events triggering.
Furthermore, if there are 20 vector objects in one view,
hese events would be triggered 20000 in one frame.
It's insane, actually I could figured out that happens.
and it took a lot of cpu consumption in some vector usages.
efl_gfx_path_commit() is my idea to avoid this.
When path is ready, the path need to get this api call in the last
to make object changed properly.

efl_gfx_path itself took care of efl_gfx_shape data but its heirarchy was
conceptually wrong. Even efl_gfx_shape is mixing the efl_gfx_path...
Damend design...
Some of derived classes of efl_gfx_path (i.e. Vg.Node and Vg.Container) are
none of the Path acutally. They are just mixing Path's interpolation interface.
So, Here patch changes VG.Node to stop calling the super's interpolate method
and Vg.Shape to call both super -gfx_shape and vg_node- interpolate method.
@fix T6996
This changes a lot of things all across the EFL. Previously,
methods tagged @const had both their external prototype and
internal impl generated with const on object, while property
getters only had const on the external API. This is now changed
and it all has const everywhere.
Ref T6859.
A few classes allow their objects to be duplicated, so they should all
use the same interface.
Also, rename VG's dup to copy_from as it's not conforming to the
definition of dup.
Efl.Object.event_callback_call no longer calls legacy smart callbacks;
calling only event callbacks registered with the given event description
pointer.
Create the method Efl.Object.event_callback_legacy_call to inherit the old
behavior from Efl.Object.event_callback_call, calling both Efl.Object events
and legacy smart callbacks.
Update all other files accordingly in order to still supply legacy
callbacks while they are necessary.
realloc() can return NULL if size is 0. It's like free().
So, the usage here is correct, and there are probably no
points to interpolate between anyway. I wonder if there
can be commands without points, though.
Fixes CID 1293004
I just ran my script (email to follow) to migrate all of the EFL
automatically. This commit is *only* the automatic conversion, so it can
be easily reverted and re-run.
As I don't see the use of inheritance for stroke anymore, we will use internal access
rather than inherited get/set function. This behavior can be reverted if anyone find
a real use case for it.

This now generate more optimized path by reducing the use of arc and
switching to only line whenever possible.

This allow to reduce the number of generated arc, but doesn't follow
SVG specification. This is just used internally and can't be used by
outside call.

1. according to svg path specification, path string may or may not contain ',' as the separator
with current parsing logic we were expecting a ',' after each segment.
2. relative cubic bezier parsing was wrong as we were not adding the current value to all 4 points.
3. refactored the parse_pair, parse_six and parse_quad to use same helper function
