Problem: when replacing the root element, UpdateXML
erroneously tried to mix old XML content with the

just return the replacement string.

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.

* Test results for other tests fixed due to added error #s
* Memory allocation/free issues found with running with valgrind

For grammar rules with loops like:

If we scanned scanned '+' and then met an error when parsing
MultiplicativeExpr, then we should fully stop parsing - without
trying to apply any other rules.
Fix: add "error" member into MY_XPATH structure,
and make my_xpath_parse_term() never return success
as soon as error set.
strings/xml.c:
Adding my_xml_ctype map for flags, indicating
whether a character is a space character, is a
valid identifier start character, is a valid

properly scan identifiers. Also, using this map
to scan spaces faster (instead of strchr).

fragment is not well-formed xml
Problem:
- ExtractValue silently returned NULL if a wrong XML value is passed.
- In some cases "unexpected END-OF-INPUT" error was not detected, and
a non-NULL result could be returned for a bad XML value.

- Adding warning messages, to make user aware why NULL was returned.
- Missing "unexpected END-OF-INPUT" error is reported now.

strings/xml.c:
- Making error messages better looking and clearer:
It is important because now they're seen in SHOW WARNINGS
(previously they were used only for debugging purposes).
- Adding "unexpected END-OF-INPUT" error if after scanning
closing tag for the root element some input is left
(previously this error was ignored in a mistake).
Problem source:
Qualified names (aka QName) didn't work as tag names and attribute names,
because the parser lacked a real rule to scan QName, so it understood
only non-qualified names without prefixes.
Solution:
New rule was added to check both "ident" and "ident:ident" sequences.

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.

was added recently.
