stylecontext: Split out functionality into custom object GtkCssNodeDeclaration is a new struct with copy-on-write semantics. It encapsulated the properties used to define a node in the CSS tree. The idea is to use it in various places for caching, in particular as key in hash tables.

css: Add fast-path for parent selector matching Add a fast path for parent selector matching that uses a bloom filter to quickly discard selectors that can't possibly match. Keep in mind that we match using a bloom filter, so we might accidentally include too many selectors when hash/bucket collisions occur. That's not a correctness problem though, because we'll do a real check afterwards. The idea for this change is taken from browsers, in particular WebKit.

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.

cssnode: Convert name + id from interned string to GQuark The reason for this is simply that I want to get hash functions that have their values close together, so they can fit in a smaller range (the goal here is 12 bits). By using GQuark, we get consecutive numbers starting with 1 (and applications have <1000 quarks usually), whereas interned strings can be all over the place. As a side effect we also save 64 bytes per declaration.

Move node printing to GtkCssNodeDeclaration The node declaration has all the information we are printing here (except for visibility). At the same time, redo the format to print the information in selector format, and indicate (in)visibility by enclosing the selector in square brackets.
