   changed to 2 megabytes.

*) Feature: the "proxy_half_close" directive in the stream module.

*) Feature: the "ssl_alpn" directive in the stream module.

This takes advantage of the introduction of the SYSCONFBASE variable.
Tested on NetBSD/amd64.

While there, add support for the "configtest" command in the RC script.
