Flesh out GtkConstraintGuide
...
This commit moves GtkConstraintGuide into its own
source files to avoid gtkconstraintlayout.c turning
too messy, adds max size properties and implements
getters and setters.

Drop an indirection
...
This struct is not really useful for just
a single hash table, and it gets in the way
of moving the guide code to its own file.

Fix the opposite size measurement in GtkConstraintLayout
...
We cannot use the given "for size" when querying our children, because
the constraint layout has no idea about the opposite size of its
children until the layout is complete.
Additionally, we should only suggest an opposite size for the layout if
we have one, instead of suggesting a weak zero size.

Remove size constraints from ConstraintLayoutChild

The size constraints are transient to measurement and allocation, so
they don't really need to be stored inside the GtkLayoutChild subclass
created by a GtkConstraintLayout.

constraints: Make internal consistency required

The relations between left, right, width
and top, bottom, height are required for
internal consistency. It doesn't make sense
to ever drop these.
Changing the strength of these relations makes
my systems behave much more stable.

Add constraint solver
...
GtkConstraintSolver is an implementation of the Cassowary constraint
solving algorithm:
http://constraints.cs.washington.edu/cassowary/
The Cassowary method allows to incrementally solve a tableau of linear
equations, in the form of:
x = y × coefficient + constant
with different weights, or strengths, applied to each one.
These equations can be used to describe constraints applied to a layout
of UI elements, which allows layout managers using the Cassowary method
to quickly, and efficiently, lay out widgets in complex relations
between themselves and their parent container.

Fix a crash in action muxer destruction
...
I've seen a crash when the action muxer gets
disposed during widget destroy, and tries to
disconnect from widget signals too late.
There is no real need to disconnect, since the
only time an action muxer is going away is when
its widget is destroyed, so just don't do it.
