This commit is still way too big, but I couldn't make it smaller.
It transitions the old CSS parser to the new parser. CSS parsing is now
tokenized, everything else is probably still buggy.
We can't try to get an integer because ultimately integer getters
support the same shenanigans that numbers and percentages do with calc()
and whatnot.
This would only happen if the last element was deprecated, but it should
be avoided anyway.
CID 1388852 (#1 of 1): Out-of-bounds read (OVERRUN)
12. overrun-local: Overrunning array pseudo_classes of 16 32-byte
elements at element index 16 (byte offset 512) using index i + 1U (which
evaluates to 16).
It was "Missing name of pseudo-class", but the real problem is exactly
the opposite: we /have/ been given a name, but it is not a valid one.
Change it to "Invalid name of pseudo-class" to minimise confusion.
Putting the deprecated class behind the official variant does
not work for the case of :focus and :focused - we were matching
:focus and leave a dangling 'ed'. So, put the deprecated classes
before the official variant, and explicitly mark them as deprecated.
I hadn't noticed the :drop() pseudo state in the CSS4 Selectors
spec when I added this a while ago. This commit renames
GTK_STATE_FLAG_DND to GTK_STATE_FLAG_DROP_ACTIVE and adds
:drop(active) as equivalent to the :dnd pseudo state.
When printing a "compound selector", make sure the name and universal
selectors are printed at the beginning and class, id, etc. selectors are
printed last.
The patch did not check for Visual Studio 2008 correctly, plus it
would break the build on later Visual Studio versions, as it should
be __popcnt(), not __popcount(). Fix that.
The popcount builtin was added in GCC after version 4.2 (which is what
some *BSDs are using), which means we need to be more specific when
using it than just asking for GCC.
While we're at it, we can improve the compiler detection, and use a
builtin popcount on Clang ≥ 3.1 and MSVC 2008.

My statistics show that more than half of all calls end up
with 0 matches, so we can avoid some overhead by not allocating
an array at all in this case.
We are dealing with really short lists here.
95% are < 10 matches, and the longest I've been able to record was 19.
So just do away with the hash table and do sorted insertion in
the array directly.
I removed it in 14f5ce7108 because I
thought it was unnecessary, but it wasn't. When we build a tree like
this:
.matches ─┬─ .doesntmatch
└─ .alsodoesntmatch
We would get the changes for the .matches part returned. This is however
only right if that node of the tree contains results. If results only
exist with the child nodes (all of which don't match), then this part
should not match either.
The new region selector tracks more than just one soimple selector, so
it requires some more advanced specificity tracking.
Technically, this is still not correct, because it will report the same
specificity for
tab:sorted
and
tab:sorted:sorted
(and the second selector will be printed as the first) but this is
regions, so meh.
This is just a way to handle regions more conveniently. What this does
is to change the descendant matcher into a maybe-descendant matcher
whenever the current object we're parsing might be a region. Because "*"
might also refer to a region and not just a new element.
See testsuite/reftests/css-match-region-matches-star.ui for a testcase.
