Subject: [PATCH] Install errcodes.txt for use by extensions.

Maintainers of out-of-tree PLs typically need access to the set of error
codes.  To avoid the need to duplicate that information in some form in PL
source trees, provide errcodes.txt as part of a server installation.

Author: Thomas Munro, based on a suggestion from Andrew Gierth
