  Bug#24747 XPath error with the node name "Text"
  
  Problem: keywords, nodetype names and axis names
  didn't work in node name context.
  
  Fix:
  1. Changes in lexem scanner behaviour when an identifier has been read:
  - search through axis names and return MY_XPATH_AXIS_xxx only
    when identifier is followed by two semicolons. Don't check axis
    names and return MY_XPATH_IDENT of not followed by two semicolons.
  - search through nodetype names and return MY_XPATH_LEX_NODETYPE
    only when identifier is followed by left parenthesis.
    Don't check nodetype names and return MY_XPATH_LEX_IDENT when
    not followed by parenthesis
  2. Change in syntax analizer: QName scanner now accepts keywords 
     AND, OR, MOD, DIV as valid node names.
