webkit: fix build with bison 2.6

WebKit 1.2.7 does not build with Bison 2.6, but Bison 2.6 is our
host-bison, so if the build machine has bison 2.6, or if by chance it
gets built before webkit, then the build fails with errors such as:

  http://autobuild.buildroot.org/results/0b7cfbebd4388cabfa243b5ef74e3b6316fd9fd9/build-end.log

(the real error is not visible due to the overwhelming number of
warnings).

So, we add a patch that modifies WebKit to make it compatible with
Bison 2.6 (patch taken from upstream), and we also add 'host-bison' to
the WebKit dependencies, so that we are sure that a well-known version
of bison is used.

++
++        Build fix with newer bison 2.6.
++        https://bugs.webkit.org/show_bug.cgi?id=92264
++
++        Reviewed by Adam Barth.
++
++        As stated in http://www.gnu.org/software/bison/manual/html_node/Table-of-Symbols.html
++        YYLEX_PARAM and YYPARSE_PARAM are depecreated since version 1.875. So far all Mac OS
++        version I had access to as well as recent Linux runs at least version 2.3 so it's safe
++        to use the replacement of these deprecated macros in favor of %lex-param and %parse-param.
++        As announced http://lists.gnu.org/archive/html/info-gnu/2012-07/msg00011.html with the release
++        of version 2.6 YYLEX_PARAM and YYPARSE_PARAM are not supported anymore.
++
++        No new tests : build fix and the patch should not trigger any regressions
++
++        * css/CSSGrammar.y:
++        * css/CSSParser.cpp:
++        * xml/XPathGrammar.y: Refactored a bit to not use an intermediate PARSER define.
++        * xml/XPathParser.cpp: bison 2.6 declare xpathyyparse in the .h file now, i.e. XPathGrammar.h
++        therefore including this file within the namespace {} declarations leads to xpathyyparse being
++        defined part of WebCore::XPath namespaces but the actual implementation of xpathyyparse is in XPathGrammar.cpp
++        (generated) and not implemented within the WebCore::XPath so it lead to linking issues. Last, XPathGrammar.h needs 
++        to be included after the other includes as it uses some XPath types. It breaks the style but CSSParser.cpp is doing the same.
