While looking around to fix the pg_malloc(0) issue, I noticed that
various other pieces of code such as pg_basebackup have essentially
identical functions, except they're called xmalloc(). I propose to
standardize all these things on this set of names:
pg_malloc
pg_malloc0 (for malloc-and-zero behavior)
pg_calloc (randomly different API for pg_malloc0)
pg_realloc
pg_free
pg_strdup
Any objections?
