Thread: pgsql: Check LIBXML_VERSION instead of testing in configure script.

Check LIBXML_VERSION instead of testing in configure script.

We had put a test for libxml2's xmlStructuredErrorContext variable in
configure, but of course that doesn't work on Windows builds.  The next
best alternative seems to be to test the LIBXML_VERSION symbol provided
by xmlversion.h.

Per report from Talha Bin Rizwan, though this fixes it in a different way
than his proposed patch.
