pgsql: * construct "struct {} list [] = {}" confuses pgindent - split

Log Message:
-----------
* construct "struct {} list [] = {}" confuses pgindent - split those.
It was a bad style to begin with, and now several loops can be clearer.
* pgcrypto.c: Fix function comments
* crypt-gensalt.c, crypt-blowfish.c: stop messing with errno
* openssl.c: use px_free instead pfree
* px.h: make redefining px_alloc/px_realloc/px_free easier
