14c9ae88db Bug 773296 - Part 11: Give nsCSSParser and nsCSSScanner the ability to save/restore their current input state. r=dbaron 
This adds functions to nsCSSParser and nsCSSScanner that let us save the
current input position (and corresponding information like line/column
number) and parser pushback, and be able to restore it later.  We'll use
this when rewinding the scanner after we first encounter a property with
a variable reference and go back to reparse it as a token stream.

6c08a4ff75 Bug 773296 - Part 9: Give nsCSSScanner the ability to remember when it encounters a "var(" token. r=dbaron 
This is the first part of handling variable references in regular
properties.  We have the scanner set a flag whenever it returns a "var("
token, so that when we come to the end of parsing a property that
failed, we know that it is because of a variable reference.

4fb5922824 Bug 773296 - Part 8: Resolve and compute CSS variables. r=dbaron 
We add a new class CSSVariableResolver whose job is to take the
inherited computed variables and the specified variable declarations and
to perform cycle removal and resolution of the variables, storing the
result in the CSSVariableValues object on an nsStyleVariables.  We use
CSSVariableResolver in nsRuleNode::ComputeVariablesData.

The variable resolver does this:

  1. Asks the CSSVariableValues and CSSVariableDeclarations objects
     to add their variables to it.
  2. Calls in to a new nsCSSParser function
     EnumerateVariableReferences that informs the resolver which
     other variables a given variable references, and by doing so,
     builds a graph of variable dependencies.
  3. Removes variables involved in cyclic references using Tarjan's
     strongly connected component algorithm, setting those variables
     to have an invalid value.
  4. Calls in to a new nsCSSParser function ResolveVariableValue
     to resolve the remaining valid variables by substituting variable
     references.

We extend nsCSSParser::ParseValueWithVariables to take a callback
function to be invoked when encountering a variable reference.  This
lets EnumerateVariableReferences re-use ParseValueWithVariables.

CSSParserImpl::ResolveValueWithVariableReferences needs different
error handling behaviour from ParseValueWithVariables, so we don't
re-use it.

CSSParserImpl::AppendImpliedEOFCharacters is used to take the
value returned from nsCSSScanner::GetImpliedEOFCharacters while
resolving variable references that were declared using custom
properties that encountered EOF before being closed properly.

The SeparatorRequiredBetweenTokens helper function in nsCSSParser.cpp
implements the serialization rules in CSS Syntax Module Level 3:

68ac09e29e Bug 836530: Make all non-ASCII characters be CSS identifier characters. r=bzbarsky 
This is as was proposed in
http://lists.w3.org/Archives/Public/www-style/2013Jan/0394.html
and resolved in the CSS Working Group's teleconference on 2013-01-30.

This removes a difference between Gecko and other browsers.
