Using the multi-seat support, Evas is able to handle multiple focused objects.
This implementation allows one focused object per seat.
This patch introduces new APIs and events to handle this new scenario,
while keeping compatible with the old focus APIs.
This combines evas canvas functions to list and query
touch points into a single iterator:
- evas_touch_point_list_count
- evas_touch_point_list_nth_xy_get
- evas_touch_point_list_nth_id_get
- evas_touch_point_list_nth_state_get
This also fixes a number of issues related to feeding fake
input events.
Note: I wanted to add delta x,y information as well but it's
in fact not really possible outside the event callback itself,
as the previous x,y position will not be updated unless there's
an event.

This removes:
Efl.Event interface
And renames:
Efl.Event.Input -> Efl.Input.Event
Efl.Event -> Efl.Input.Event (merged)
Efl.Event.Pointer -> Efl.Input.Pointer
Efl.Event.Key -> Efl.Input.Key
Efl.Event.Hold -> Efl.Input.Hold
This also moves some interfaces from efl/ to evas/ where they
belong better.
This allows renaming Eo_Event to Efl_Event.
Evas.Common_Interface not only had a bad name, it also
wasn't in line with how we can get a loop object, for
instance.
Use eo_provider_find in each implementing class.
evas canvas will be removed from eo.
evas_output_XXX APIs are usually used by widget or e17.
I decided not open these kind of APIs to eo.
app can use the size of elm win instead of evas output apis.
Summary:
* pointer.button is DATA32 which is unsigned, so this changes the
definition of pointer_button_down_mask accordingly.
* Avoids UB in mask generation:
lib/evas/canvas/evas_events.c:1348:37: runtime error: left shift of 1 by 31 places cannot be represented in type 'int'

This lets me narrow down the remaining cases of pointers across the EFL.
The void pointers will later need to be reevaluated on per-case basis and
replaced appropriately where possible/feasible.
This is going back to the same idea as legacy. We will have
events such as:
- move
- down
- up
- in
- out
- wheel
- cancel ("new" - very rare)
Now the question is whether/how we should divide "multi" events
which start from the 2nd finger from standard mouse events. The first
multitouch finger should by default look like a mouse event.
This is still VERY experimental and not fully done yet.
All other pointer events need to be sent as well.
The legacy event system is used as a transportation mechanism,
as it is too hard to change the logic. This only adds an extra
eo event in case of move. Obviously for performance we might
want to listen to callback_add,del but that's an optimization
for later.
The whole point of sending those pointer events is to carry more
information than can be sent over legacy evas events, and unify
the events in a common format.
Complex types (i.e. list, array, hash, accessor etc.) now do not require
pointers with them anymore (the pointer is implied) and the same goes for
class handles. Eolian now explicitly disallows creating pointers to these
as well. This is the first part of the work to remove pointers from Eolian
completely, with the goal of simplifying the DSL (higher level) and therefore
making it easier for bindings (as well as easier API usage).
@feature
It has been decided that we would not use any namespace for interface
and they will sit in efl main namespace.
This patch doesn't correct the naming of the event has we don't have a
prefix for event. We do still have EFL_ANIMATOR_EVENT_ANIMATOR_TICK,
instead of a nicer EFL_EVENT_ANIMATOR_TICK.
The definition of 'framespace' in the canvas eo file is incorrect.
Framespace is the space occupied by the window frame within the canvas viewport

Instead of "@in type name;" we now use "@in name: type;". This change
is done because of consistency with the rest of Eolian; pretty much
every other part of Eolian syntax uses the latter form.
This is a big breaking change in the .eo format, so please update your
.eo files accordingly and compile Elementary together with the EFL.

Summary:
This patch set adds the necessary code to expose device axis state to applications. This was primarily written with graphics tablets in mind, which -- in addition to acting like a mouse -- also provide information about pen pressure, tilt, etc. Other devices could potentially benefit from this API as well: touchscreens, joysticks, knob controllers, "spaceballs", etc.
Whenever an update to the device state is recieved, an "Axis update" event is synthesized. This event contains the updated information, typically scaled and normalized to a particular logical range (e.g. zero to one for pressure, -pi to pi radians for angles, etc.). Information about the tool which generated the event is also stored so that applications can disambiguate events from multiple devices (or in the case of multitouch screens, individual fingers).
This API is only wired up for use with X11 at the moment. Support for other backends (e.g. Wayland) should be easy to add for those familiar them.
**Note**: The following is a list of changes from the "v2" patches originally sent to the mailinglist
//Define and implement new Ecore_Event_Axis_Update events//
* Harcode axis labels instead of including xserver-properties.h
* Use C89-style comments
* Use doxygen comments
* Update comment text to note axes with unbounded/undefined ranges/units
* Create "Ecore_Axis" and "Ecore_Axis_Label" typedefs
* Reference typedef'd instead of raw types
* Adjust how we count through valuators to support tilt/az
* Add support for tilt and azimuth
* Tweak memory management in case number of valuators differ
* Expand TWIST axis normalization to declared range
* Only normalize TWIST axis if resolution == 1 (wacom bug)
* Cache label atoms on first use to minimize round-trips
//Implement EVAS_CALLBACK_AXIS_UPDATE event and friends//
* Update to doxygen comments
* Update comment text to note axes with unbounded/undefined ranges/units
* Typedef 'Evas_Axis_Label', 'Evas_Axis'
* Move typedef for 'Evas_Event_Axis_Update'
* Reference typedef'd instead of raw types
//Wire the Ecore and Evas implementations of axis update events together//
* Expose ecore_event_evas_axis_update in Ecore_Input_Evas.h
* Move ecore_event_evas_axis_update to more logical position
//DEBUG: Add axis update logging to evas-multi-touch.c//
* Removed from patch set
//Make evas-multi-touch demo use new axis functionality//
* Have pressure adjust rectangle brightness instead of size
* Use more available axis data when rendering rectangle (azimuth, tilt, twist)
Test Plan: The evas-multi-touch demo was updated to support axis update events. A graphics tablet was then used to verify that the pressure, azimuth, tilt, and twist data was coming through correctly.

This is a critical performance issue that was introduced during our move
to eo2. This code was still eo1 style so I guess it was just forgotten.
The result is that canvas with large numbers of widget were slower after
the migration.
