* pattern.c, xpath.c, include/libxml/pattern.h: Further enhancement for XPath streaming, consolidated with schemas usage of pattern.c. Added a new enum xmlPatternFlags. * doc/*, testapi.c, elfgcchack.h: updated to reflect new enum. * test/XPath/tests/mixedpat, test/XPath/docs/mixed, result/XPath/mixedpat: added regression test for problems reported in bug306348
