pgsql: Rename our substitute qsort to pg_qsort at the link-symbol level - Mailing list pgsql-committers

Log Message:
-----------
Rename our substitute qsort to pg_qsort at the link-symbol level (but
provide a macro so code can still just say qsort).  Avoids linker warnings
on pickier platforms such as Darwin, and outright failure on MSVC.
