Rewrite pg_regress as a C program instead of a shell script.

This allows it to be used on Windows without installing mingw
(though you do still need 'diff'), and opens the door to future

On some systems, the default Bourne-compatible shell
(<filename>/bin/sh</filename>) gets confused when it has to manage
too many child processes in parallel. This may cause the parallel
test run to lock up or fail. In such cases, specify a different
Bourne-compatible shell on the command line, for example:
