8a3a617475 cssselector: Add initial support for :not()
:not() works for names, ids, classes and pseudoclasses based on states.

It does not yet work for positional pseudoclasses (like :last-child or
:even) as there is region madness going on with those.

df1d331713 update_type_references: Deal with type_refs_ht being NULL
This can apparently happen, and it was breaking make check
on my system, by causing it to throw  a critical out of
g_hash_table_iter_init from here.

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.

eb4667b6e1 css: Do get_change directly on the tree without matching first
Rather than first collecting matches and then getting the change
for them we do the change collection directly on the tree. This

146b6f3a93 css: Ensure the tree built is always the same
We add some "artificial" ordering to the otherwise unordered
tree nodes. This means the tree will be the same every time for the
same input. This is good because e.g. tree order affects the
reordering of the simple selectors, which may affect how
css providers are printed, which need to be consistent for
the css tests to work.

d6932dd823 css: Don't reorder some selectors when building selector tree
When building the tree we generally reorder the selectors inside
the same simple selector in order to pick a good first selector
to balance the tree better. However, some kinds of selectors
can't really be reordered, even thought they are simple.

This is since the matching code for some types handle
the existance of a directly preceeding selector differently:

 REGION and ANY selectors look for a DESCENDANT previous
 POSITION selector look for a REGION previous

daefb12a23 css: Add GtkCssSelectorTree creation and matching
From a set of GtkCssSelectors and the rulesets they match to
we create a large decision tree that lets us efficitently match
against all the rules and return the set of matched rulesets.

The tree is created such that at each level we pick the initial rule[1]
in all the considered selectors for that level and use put the
one that is in most selectors in the node. All selectors matching that
are put in the previous part of the tree.

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.

35a0fb09ac css: Rewrite selectors
Previously we kept a Selector object for every "simple selector" (term
from CSS spec). Now we keep one for every match operation. So given the
selector
  ".a b:focus"
we will have 4 elements:
  - pseudoclass ":focus"
  - element "b"
  - match any desendant (the space)
  - class ".a"
Each of those is represented by a "selector class" which is basically
the collection of vfuncs for this selector.

e9adaabc5e Rename 'window-unfocused' to 'backdrop'
'window-unfocused' is too long and mentions "focus" which is historically
loaded with the meaning "input focus".

'backdrop' isn't generally used in GUI speak and still conveys the state the
widgets in an unfocused or background toplevel window are in.

a6ac53e2a9 css: Change prototype of _gtk_css_selector_matches()
Passing the length of the widget path that is relevant is not necessary
anymore, it was only useful for inheritance. Instead, we now pass the
state flags and let the selector do the state matching for us.

fc88b0f47c css: Rewrite selectors
Selectors now go into their own C file. The new selectors are modeled a
lot closer to the CSS spec. In particular the specificity computation
matches CSS 2.1 exactly.
