Fixed wrong number of arguments specified for 'deprecated' attribute

The was an issue with the GCC `__attribute__((deprecated))` syntax in
the macro definition of `XML_DEPRECATED`. The problem was that older GCC
versions don't accept a string message argument in the deprecated
attribute.

See https://gcc.gnu.org/gcc-4.5/changes.html

Cherry-pick with minor modifications.
