implement `listen on' Listening by default on all the addresses is so bad I don't know why I haven't changed this before. Anyway. Add a `listen on $hostname port $port' syntax to the config file and deprecate the old "port" and "ipv6" global setting. Still try to honour them when no "listen on" directive is used for backward compatibily, but this will go away in the next next version hopefully. At the moment the `listen on' in server context don't filter the host, i.e. one can still reach a host from a address not specified in the corresponding `liste on', this will be added later.

use the default prefork in tests

regress: use -P with an absolute path

revert aae8f6bf2b it's just not worth it to inflict this breaking change to the users.

make the various strings in the config fixed-length will help in future restructuring to have fixed-size objects.

don't count twice the failing tests on gmid crash

change the flags to be consistent with other OpenBSD daemons -d is `debug' (run in the foreground) -f to load the configuration file adjust regress and contrib accordingly

adjust regress to use `ge' for the old configless test

count ran/failed tests number

posixify lib.sh: use = instead of == for test(1)

remove unused function

add set_proxy to simplify testing + more checks in test_proxy_with_certs

set prefork to 1 during regress

don't print `config OK'

switch to the new gg for the regress suite
