Fix null-dereference crash in parse_xml_decl().
parse_xml_decl's header comment says you can pass NULL for any unwanted
output parameter, but it failed to honor this contract for the "standalone"
flag. The only currently-affected caller is xml_recv, so the net effect is
that sending a binary XML value containing a standalone parameter in its
xml declaration would crash the backend. Per bug #6044 from Christopher
Dillard.
In passing, remove useless initializations of parse_xml_decl's output
parameters in xml_parse.
Back-patch to 8.3, where this code was introduced.
