82b340f6f0 cssprovider: Keep two hash tables per ruleset
One for the style properties, one for the widget style properties.
This way we can make one hash table by pspec which means we don't have
to repeat the pspec lookup.

399a439103 cssprovider: Add a new setter for rulesets
We now have set-by-pspec (which is used for normal style properties) and
set-by-name (which is used by widget properties).

0318ab2ce1 cssprovider: Refactor handling of rulesets
Keep rulesets as an on-stack/heap structure instead of allocating all
instances separately.
Also, pass a ruleset to the ruleset parser, so we can make the ruleset
parser do lots of fancy things that might be useful for performance.

b37f9fdf81 css: Implement inherit properties
Huge performance hit (slows down things roughly by a factor of 3), but
necessary for CSS conformance and for implementing "inherit" and
percentages.

25c396409c reftests: Check style property order
Ensure that style properties are read in the correct order, by having a
property twice with vastly different values.

c1dc3e9372 css: Refactor code to do property lookups earlier
We want to ook up the property in the CSS parser, so we can do fancy
things with it. We currently don't but we want to later.

82399bf457 styleproperties: Speed up by not optimizing
g_quark_try_string() takes a lock and then does a hashtable lookup. So
just using a string hash table for properties is faster.

4c92fb2b5d styleproperties: Speed up style_property_lookup()
Use the already existing bsearch version instead of iterating the array
manually.

beba515243 styleproperties: Use the pspec as the hash table key
The code used the quarked name before, but when we already have the
pspec we want to have a lookup that does not involve quarking. And
lookup is equally fast if we only have the name.

8605a2a10a cssprovider: Speed up gtk_widget_style_get() property lookups
Previously we got the list of all matching rules and then iterated it to
find the first one that had the property. Now we look while matching
rules, so we don't lookup rules that we don't need.

1400644069 reftests: Add a test ensuring selectors don't match children
Previously, the selector "Foo" would not only match Foo widgets, but
also all widgets that are descendants of Foo.

f3ed498c5b reftests: Add a test for descendant CSS selectors match
In widget hierarchy like "Foo Bar Bar Baz", we want the selector "Foo >
Bar Baz" to match, because it matches the elements 1, 2 and 4.
Previously, the selector only matches the Bar at position 3 and then
failed because it wasn't preceded by a Foo.

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.

7ccb9db79e css: Rewrite the parser
Instead of relying on GScanner and its idea of syntax, code up a parser
that obeys the CSS spec.
This also has the great side effect of reporting correct line numbers
and positions.

Also included is a reorganization of the returned error values. Instead
of error values describing what type of syntax error was returned, the
code just returns SYNTAX_ERROR. Other messages exist for when actual
values don't work or when errors shouldn't be fatal due to backwards
compatibility.

d6c6a0bcc0 cssprovider: Reimplement gtk_css_provider_load_from_path()
Call gtk_css_provider_load_from_file() instead of the internal function.
This has two advantages:
1) It simplifies the code a lot
2) It gets rid of GMappedFile usage. GMappedFile does not work
   everywhere, so this is finally portable.
