nothing to render.

Part of the long running effort to reduce the prevalence of `session_t`.
After this, functions that communicate with X can make use of the error
handling machinary (set_ignore_cookie, set_cant_fail_cookie) without
needing to take a `session_t` parameter.
This commit converts everything to use the new struct `x_connection`,
most of the conversions are mechanical.

This is used to create image masks that can be used to mask out
`compose` regions. For example, this can be used to mask out window body
so shadow won't be painted on them.
This could be more efficient than using rectangular regions for masking,
when there are a large number of rectangles; or more flexible, in the
case of window with rounded corners.

This is meant to be used to detect GPU resets.
Implemented in the glx backend using the GL_ARB_robustness extension.

Currently there is some inconsistency in how image_op is implemented
across backends. The glx backend applies some of the image operations
lazily, and not always in the order the operations were made; while the
xrender backend applies the operations eagerly. This can lead to
different render result in some cases.
Instead of trying to preserving the order of operations, which would be
unnecessary, we re-model the API to better reflect the implementation.
We make it clear that setting the property doesn't change the image
data, and properties are only applied during composition and in a
specific order.
This makes sure the render result looks consistent across backends.
Should also improve the performance of the xrender backend, even if only
slightly.
Also distill out the property management code so they can be shared.

Potential use: to read the border color of a window, so we could draw
rounded border when we round the corners of the window.

**Work-in-Progress**
Add `dual_kawase` to configuration and argument parsing. Allow `kawase`
for backward compatibility. Add `--blur-strength` parameter for
blur-method `dual_kawase`.
Update documentation to reflect the new blur-method and parameters.
leftovers:
1) config file path. Has to implement compatibility functionalities before
we can change it.
2) links in man pages. Has to migrate the repo first.
3) _COMPTON_SHADOW, it has become a defacto standard, so we have to keep
supporting it.
4) dbus names, undecided whether we should/could change it.

Dummy backends are backends that doesn't render anything on to the
screen or the target window. But they are still be useful for debug
purposes, and can be useful for other things too.

To prepare for different blur methods, the blur interface of backends
has been splitted into two parts.
Now to use blur, a blur context must be created first; then, the blur
method should be called with the blur context created.
Updated the existing backends to the new interface. Also implemented
handling of the new blur options.
