Delete contrib/xml2's legacy implementation of xml_is_well_formed().
This function is unreferenced in modern usage; it was superseded in 9.1
by a core function of the same name. It has been left in place in the C
code only so that pre-9.1 SQL definitions of the contrib/xml2 functions
would continue to work. Eleven years seems like enough time for people
to have updated to the extension-style version of the xml2 module, so
let's drop this.
We did this once before, in 20540710e
, and then reverted it because
the intended change of PGDLLEXPORT markings didn't happen. This
time the reason is to suppress link-time duplicate-symbol warnings
on AIX. That's not worth a lot perhaps, but the value of keeping
this function has surely dropped to about zero by now.
