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
improvements such as message localization.

-The parallel regression test script (gmake check) is known to lock up

-/sbin/sh. To fix this problem, you will need PHCO_30269 with its
-dependent patch or successor patches:

-    PHCO_29816  s700_800 rc(1M) scripts cumulative patch

-To work around this problem, use ksh to run the regression script:
-
-	gmake SHELL=/bin/ksh check
-
-If you see that the tests have stopped making progress and only a shell
-process is consuming CPU, kill the shell process and start over with the
-above command.
