Parser: move match() into core/parse-xml.c

The match() function compares a pattern with a name with
a twist: The name may either end in '\0' or '.'. If pattern
and name match, a parsing function is called on a buffer and
a destination value. The result of the parsing is not checked.

This seems awfully XML-specific and therefore move the function
from the general parse.c to the specialized parse-xml.c unit
and make it of local linkage.
