Bug#16233: XML: ExtractValue() fails with special characters

Browse Source 
ExtractValue didn't understand tag and attribute names
consisting of "tricky" national letters (e.g. latin accenter letters).
It happened because XPath lex parser recognized only basic
latin letter a..z ad a part of an identifier.

Fixed to recognize all letters by means of new "full ctype" which
was added recently.


mysql-test/r/xml.result:
  Adding test case
mysql-test/t/xml.test:
  Adding test case
sql/item_xmlfunc.cc:
  Using recently implemented "true" ctype functionality
      to treat all national letters as valid tag names,
      Only basic latin letters worked so far.
strings/ctype-simple.c:
  A bug fix: ctype is array of 257 elements,
      adding offset to address correct element.
