Summary:
add check new_gcc into the gadman's gadget add handler to prevent invalid ref_count increase
while moving between two zones. and also add object clean code for new_gcc and drag_gcc
when gadget is dropped.
Fixes T722
Test Plan:
1. create clock module on gadcon desktop (settings->gadgets, select "background" under layers, click "configure layer" and add a clock gadget).
2. drag clock gadget from one screen to the other. drop it there.
3. drag clock back to first screen
4. right click on clock and select "clock->remove".

huge fustercluck commit because there wasn't really a way to separate out the changes. better to just rip it all out at once.
* compositor and window management completely rewritten. this was the goal for E19, but it pretty much required everything existing to be scrapped since it wasn't optimized, streamlined, or sensible. now instead of having the compositor strapped to the window manager like an outboard motor, it's housed more like an automobile engine.
** various comp structs have been merged into other places (eg. E_Comp_Zone is now just part of E_Zone where applicable), leading to a large deduplication of attributes
** awful E_Comp_Win is totally dead, having been replaced with e_comp_object smart objects which work just like normal canvas objects
** protocol-specific window management and compositor functionality is now kept exclusively in backend files
** e_pixmap api provides generic client finding and rendering api
** screen/xinerama screens are now provided directly by compositor on startup and re-set on change
** e_comp_render_update finally replaced with eina_tiler
** wayland compositor no longer creates X windows
** compositor e_layout removed entirely
* e_container is gone. this was made unnecessary in E18, but I kept it to avoid having too much code churn in one release. its sole purpose was to catch some events and handle window stacking, both of which are now just done by the compositor infra
* e_manager is just for screensaver and keybind stuff now, possibly remove later?
* e_border is gone along with a lot of its api. e_client has replaced it, and e_client has been rewritten completely; some parts may be similar, but the design now relies upon having a functional compositor
** window configuration/focus functions are all removed. all windows are now managed solely with evas_object_X functions on the "frame" member of a client, just as any other canvas object can be managed.
*** do NOT set interceptors on a client's comp_object. seriously.
* startup order rewritten: compositor now starts much earlier, other things just use attrs and members of the compositor
* ecore_x_pointer_xy_get usage replaced with ecore_evas_pointer_xy_get
* e_popup is totally gone, existing usage replaced by e_comp_object_util_add where applicable, otherwise just placed normally on the canvas
* deskmirror is (more) broken for now
* illume is totally fucked
* Ecore_X_Window replaced with Ecore_Window in most cases
* edge binding XWindows replaced with regular canvas objects
* some E_Win functionality has changed such that delete callbacks are now correctly called in ALL cases. various dialogs have been updated to not crash as a result
comp files and descriptions:
e_comp.c - overall compositor functions, rendering/update loop, shape cutting
e_comp_x.c - X window management and compositor functionality
e_comp_wl.c - Wayland surface management and compositor functionality
e_comp_canvas.c - general compositor canvas functions and utilities
e_comp_object.c - E_Client->frame member for managing clients as Evas_Objects, utility functions for adding objects to the compositor rendering systems
additional authors: ivan.briano@intel.com
feature: new compositor
removal: e_border, e_container, e_popup
* handle zone changes without forcing a redraw (no more flickering, hooray)
* correctly handle overlay gadcons
* also correctly handle creation of overlay
* merge gadman overlay to comp canvas using a popup
* unify zone change handlers
* remove stupid container shape change handler (wtf was this supposed to do?)
* better dnd usage
* dnd canvas removed, dnd objects now drawn directly on compositor canvas
* dnd now correctly picks the top-most dnd-receiver location as its drop target instead of just using the first one in the list
* various other small changes to go along with this
* added a number of new e_comp functions and macros
* options for disabling effects on objects: this option does not currently have any effect
* all modules which used gadcon popups have been adjusted
* all modules which used input windows to detect close events for gadcon popups have been adjusted to use new popup autoclose functionality
* shelves are now always drawn on the compositor canvas, meaning objects will never get clipped by the shelf (ticket #1810)
* shelves no longer have an event object
SVN revision: 84060
* remove xwin for container canvas: now drawn directly on the compositor canvas
* added SHAPE_DEBUG define for bored developers
* bindings now use new e struct for mouse/wheel events
* container+zone now get mouse events from smart callbacks instead of x events
* rename comp api namespace
* change comp underlay theme to have a swallow for the wallpaper
* add names to all zone/container/comp objects to make debugging much easier
* some minor related updates to go along with this

In order to move composite inside the core we need to kill the
use_composite option. However in some places it is being used to switch
between ARGB and shaped windows. It doesn't make much sense to keep the
advanced/engine dialog to let the user toggle this options if we have
composite always enabledm, but lets allow the user to shoot
himself on the foot (for now).
Next step will be to move the comp module files to core so user can't
unload it anymore.
