1cd9396154 css: Review error messages 
... and move them from _gtk_css_parser_error() to the proper new error
message.

e0a01ba174 css: Redo for new parser 
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.

607502ef43 cssparser: Add gtk_css_parser_consume_url() 
Another slight renaming and semantics change.

acddc317da cssparser: Add gtk_css_parser_resolve_url()

7f99c1e588 cssparser: Split integer gettig into has/consume functions 
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.

5f3e5a0406 cssparser: Add gtk_css_parser_try_delim() 
For parsing single code point delimiters. Also port calc() to use this.

23080d47b5 cssparser: Get rid of _gtk_css_parser_try_double() 
Use gtk_css_parser_consume_number() everywhere instead.

f0d2f99239 cssparser: Add gtk_css_parser_consume_string() 
Well, just rename _gtk_css_parser_read_string() for the new semantics,
but this sounds cooler.

dce8c11b07 cssparser: Drop _gtk_css_parser_has_prefix() 
Replace it with has_ident/has_function. The old function is a typical
string matching API, not a tokenizing one.

d99ae4b6c2 cross-fade: Use gtk_css_parser_consume_any() 
.. and gtk_css_parser_consume_function().

gtk_css_parser_consume_any() is a new function that implements the CSS
spec's any combinator ||.

904a9d0c98 parser: Add gtk_css_parser_has_token() 
This is ithe first step towards converting the parsing code to use
tokens. For now, the topken type is just a magic enum value that only
works as-needed.

a938c14d11 build: Add gtk-css static library 
This library is meant to be the new CSS library that gets used from GDK,
GSK and GTK for string printing and parsing.

As a first step, move GtkCssProviderError into it.

While doing so, split it into GtkCssParserError (for critical problems)
and GtkCssParserWarning (for non-critical problems).

d9ef734458 cssparser: Simplify 
Remove the uint parser (and use the int parser in the one user of it).

And avoid unnecessarily going through a macro.

7f4b7c48e8 cssparser: Make _gtk_css_parser_try a macro 
We almost always pass a constant string to it, so use a macro and try to
trick the compiler into evaluating the 2(!) strlen() calls at compile
time.

4ac3f916d0 css: Parse hex colors with alpha value 
The CSS color spec version 4 introduces this, support has hit Safari,
Chrome and Firefox, so this looks like a feature that's here to stay.

9ef700b161 css parser: Reuse one GString 
Instead of creating a new one for every ident, name and string, just
create one GString and reuse it. This means the GString we keep around
will grow to the maximum size of any ident, name or string we parse,
which is still not terribly large.

fb47a8d714 css: Remove deprecated number-as-pixels compatibility 
Previously, for compatibility with GTK 3.0, we allowed specifying
numbers without units and interpreted them as pixels, even when the CSS
specification didn't.

Remove that now that we can break API.

3056d793a4 cssparser: Make _gtk_css_parser_has_number() a bit smarter 
Previously we just checked the first character. And if that was a "-" as
in "-gtk-some-special-value", we assumed it was a number. Which it
clearly wasn't.

Test included

b246d55472 css: Turn number values into a virtual type 
GtkCssNumberValue is now a base class for numbers.

Actual numbers are now implemented in GtkCssDimensionValue. The name is
borrowed from the CSS spec, so there.

3c54fbd3ac Use stupid quotes instead of dumb quotes 
Following a similar change in GLib a while ago.

'bla' may by stupid, but it looks less dumb than `bla'.

12683da8f7 gtk: Make functions static that don't need to be non-static 
Also remove the starting underscore from function names where
appropriate, as those functions are static now and not exported anymore.

This is part of a bunch of fixes for gcc complaining about
-Wmissing-declarations.
