Revert "Revert previous fix for #299"
This reverts commit 04fe4a76b23aa1196ffcdb822510e0a3c84ab3b3.

This brings back the previous incomplete fix attempt for #299. See the
commit message of the revert for why it's incomplete.

A different fix is then attempted, see commit xxxxxxx for how that fix
works.

However, the second fix is incomplete by itself as well. The reason is
that i3 reparent the real window to the frame first, before destroying
the placeholder client of that frame. So briefly, that frame would have
2 client windows. And the frame is mapped before the placeholder is
destroyed. So even though we only call win_recheck_client when/if the
frame window is mapped, it can still be called when there are 2 client
windows, it would pick up the wrong client window in that case.

So what we need is to combine both fixes.

The second fix makes sure we are up to date on the client window
information when we starts to listen for events on the frame window;
while the first fix would keep us up to date afterwards.

This revert also includes a fix for assertion failure raised in #371

See #299 for root cause of the bug.

win, event: delayed handling of reparent notify
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

New backends: smoothly fade blur-texture on fade-in/-out
* 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).

While those commits themselves could be useful even if they don't
completely fix #299, they come with the risks of introduce more
unforeseen bugs, which outweigh their benefit, so revert them.

A brief explanation of their problem:

The fix hinges on the destroy event of the client window to work.
However, the client window could be destroyed so fast, before we even
handle the map, or even the create, event of the frame. And we won't be
listening for substructure events on the frame at the point the client
window is destroyed. Thus completely miss the client window destroy
event.

Because of the inherent racy nature of Xorg, this approach is really
difficult to make work.

Fixes #371

event: destroy: recheck client instead of unmark client
We detach the client window from its frame when it's destroyed, so later
a new window can be attached to that frame. But turns out that's not
enough.

When i3 restarts, it attaches a placeholder window to the frame, then
the real window, and only after that, it will destroy the placeholder.
The real window will fail to attach as the frame already has a client.
When the placeholder is destroyed, we have to call recheck client to
pick up the real window that failed to attach previously.

event: destroy: unmark client when a client window is destroyed
We do nothing when a non-wm-frame window is destroyed. This will cause
trouble if a wm-frame window is reused (i.e. its child is destroyed then
a new child is reparented to it), because we didn't clear client_win.

So this commit adds a call to win_unmark_client for that case.

9332cba8df core: delayed handling of root ConfigureNotify
Previously, root ConfigureNotify is handled immediately, by resetting
the backend, which in turn releases all the window images. This puts all
the windows into a state where they don't have images attached, which
they really should be in when the screen is redirected.

(To expand a little, a window without images should only exist if:
    * It's an unmanaged window.
    * Screen is unredirected.)

Normally, this kind of window could be fine, as the next render phase
will re-acquire images for them. However, if a window in this state is
destroyed with fading enabled, then the render phase won't try to
acquire images for it, causing it to go into the main rendering function
without images attached, and trigger an assertion.

This commit delays the handling of root ConfigureNotify until the render
phase. This way, the images will be immediately re-acquired after they
are released, thus prevent this problem from happening.

Also adds a testcase for this.

Make sure window cannot enter fading when unredirected
Firstly, this breaks the assumption that when we redirect the screen,
all window is either mapped or unmapped, causing a assertion failure.

Secondly, if transition window into fading when the screen is not
redirected, the fading will not progress until the screen is redirected,
probably not the desired result.

events: don't call win_get_name for logging
win_get_name _updates_ the name of the window by querying the X server,
thus potentially changes the behaviour of the compositor when logging is
turned on (e.g. we could fail to detect window name changes, because the
name was blindly updated in a logging call without handling the name change).

We shouldn't do that.

Make potentially window destroying functions take simple pointers
Instead of pointer to pointer. The two level of pointers were used to
inform the caller the window has been destroyed (pointer set to NULL).

Now, destruction of windows are now signaled by the return value, which
is marked `must_use`.

Problem with taking pointer to pointer is that they tends to pollute the
function signatures a little bit. And we are not using it well anyways.
A lot of the callers passes pointers to local variables to those
functions, so the information about window destruction doesn't actually
bubble up. So, we switch to use just one level of pointers instead.
