60cd7cd96c css: Fix the ANY matcher state list 
The ANY and matcher was not, in fact, matching any state,
since the list of states was not up-to-date.

The same fix applies to the superset matcher as well.

192a24fa1f css: Track selected state separately 
Like the previous change, this reduces the number of
css nodes reacting to parent-state changes. The remaining
parent-state cases here are due to :link.

Before (numbers from widget-factory with Adwaita):
2247 nodes
class 612
name 2246
id 2
first-child 148
last-child 156
state 2245
hover 562
disabled 859
backdrop 1080
sibling-name 63
sibling-disabled 51
parent-class 586
parent-name 788
parent-id 2
parent-first-child 78
parent-last-child 78
parent-state 236
parent-hover 5
parent-disabled 91
parent-backdrop 4

After:
2247 nodes
class 612
name 2246
id 2
first-child 148
last-child 156
state 2245
hover 562
disabled 859

fcceac6d11 css: Track hover state changes separately 
The idea is that this reduce the amount of frequently
changing state that css nodes are sensitive to.

This is going to reduce the amount of style recomputation.

517cea36ed cssmatcher: Actually match names for widget paths 
The type is always 0 when we use names. So this would always return
FALSE. Oops.

101df329ae API: Add gtk_widget_path_iter_set_object_name() 
... and gtk_widget_path_iter_get_object_name(). This allows applications
that still use widget paths to use the new object names to get the
correct styling.

Mutter and webkit-gtk are examples here.

03312371da cssmatcher: Speed up common matching 
first-child and last-child are the most common usages of the nth-child

The code still doesn't work right, but at least it's easier to fix now.

2bf7bdd651 cssmatcher: Allow widget path matcher to take a node declaration 
The node declaration has the same functionality as
gtk_css_node_declaration_add_to_widget_path(). So instead of using that
function on a path, you can use the original path and the declaration in
a matcher.

dff52f7a04 css: Match state in siblings properly 
Previously, we always returned the state flags of the original widget
and did not consider the siblings' pseudoclasses.

Testcase is attached.

19eb1614de cssmatcher: Use widget path's state 
Don't take a state when constructing the CSS matcher. Instead, rely on
the newly introduced state in the widget path.

This way, the state can be queried not only on the first element, but on
all elements of the widget path.

a1ee2b7b82 css: Speed up name matching 
We use the new g_type_get_type_registration_serial() so that we can
cache and properly invalidate the result of g_type_from_name().

This bumps the glib requirement to 2.35.3 to get the new function.

16f2b20f96 css: Add _gtk_css_matcher_matches_any() 
This returns true if the matcher matches *anything*. We need
to check this later, because such matchers are dangerous in loops
that iterate over all parents/siblings since such loops would not
terminate.

102d10016f matcher: Add a superset matcher 
This matcher always matches only on some relvant things and ignores the
rest. This allows you to match only on name and class, but ignore state
and parents/siblings for example.

5f5bf27287 matcher: Add a matcher that matches anything 
Lesson learned: Adwaita uses all possible selector types and all of
those for parents, too. But so far no siblings.

3bdde54aaf selector: Rewrite position tracking 
We now track the position as a (type,a,b) tuple where the numbers make
up the an + b formula from CSS3 nth-child.

Also, the get_sibling() and get_sibling_index() vfuncs were replaced by
a has_position() vfunc. This is mostly so that the matcher can always
return TRUE. And I need that for the everything matcher.
