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

so i found something interesting. the grab option causes some erratic
framerate in clients IF thoise clients have to sync to the xserver and
themselves try and render more smoothly. it masically means animators
get delayed due to unusually long render times because of this. this
fixes that. this also adds a comp config version number allowing the
code to upgrade a users config to turn this off and thus allows for
future upgrades too.
without this, it was possible to break the compositor by enabling options which prevent unfullscreening a window on vdesk flip, which causes nocomp mode to remain permanently enabled, even after the window has closed
shelves are almost always around. that means that unless you magically
can do partial rendering, comp updates re-render shelf AND all
contents. for systems this means much mofre gl overhead thatn with
e17. to do a mid-way house, force zoomaps on for shelves, until evas
can auto stuff smart objects into buffers on its own based on behavior.
