This commit adds a fullscreen rule for configuring
whether the view should be drawn fullscreen on start up.
The actions "fullscreen" and "no-fullscreen" map to the two
possible state of a view and semantically operate on the same
rule list. The behavior of adding, deleting and listing rules
follows that of float and ssd.
This commit adds position and dimensions rules for configuring
the initial position and dimensions of views.
When a view is not matched by any position rules, it is centered
in the avaliable output space matching the current behavior. If
the provided position rule places the view outside of the output,
the view's position is clamped to the output bounds (with respect
to borders).
When a view is not matched by any dimensions rules, no default
dimensions is set by the server. If the provided dimensions rule
exceeds the minimum or maximum width/height constraints of the view,
the view's width/height is clamped to the constraints.
Position and dimensions rules have no effect if a view is started
fullscreen or is not floating. A view must be matched by a float
rule in order for them to take effect.
