Some versions of Perl export a macro named HS_KEY. This creates a conflict in contrib/hstore_plperl against hstore's macro of the same name. The most future-proof solution seems to be to rename our macro; I chose HSTORE_KEY. For consistency, rename HS_VAL and related macros similarly. Back-patch to 9.5. contrib/hstore_plperl doesn't exist before that so there is no need to worry about the conflict in older releases. Per reports from Marco Atzeri and Mike Blackwell.
