If a window receives multiple configure notifies in between 2 frames, we
add all the in between positions into damage, when we really just need
the starting and the end position.

Part of the configure notify handling which requires querying the X
server, has been moved into the X critical section.

Instead of handling reparent notify on the spot by updating the client
windows, setup a flag on the window and call win_recheck_client later.
This makes handling of complex scenarios easier. As example, see the
case in issue #299.
Note this is not a complete fix for #299
* Add new field `opacity_target_old` to `struct managed_win` for
tracking relevant `opacity_target` changes.
* Smoothly fade blur-texture opacity on window opacity changes (based on
window opacity), when the window was or will be fully transparent
(`w->opacity ~< 0.004`).
* Fixed alpha-clipping of the blur-texture when using `inactive-opacity` or
repeatedly setting window opacity with large fade intervals (should fix#314).
These two flags are intended for subtly different things. I can probably
justify the distinction, but it's definitely difficult to explain. And
there is no obvious benefits to keep them separate.

And a window update flag for mapping the window.
Also make sure related functions consider the case where the given window
has pending updates.

Split it into PIXMAP_STALE and SHADOW_STALE, this allows us to update
pixmaps and shadow images separately.
Also added PIXMAP_NONE and SHADOW_NONE, as redundancy to detect logic
errors.
Convenient constants and functions are provided for updating pixmap and
shadow together.
