use the types block instead of `map' in the tests too

break out if check_reply fails it's not a problem when we have only one check_reply at then end, since $? is kept across function boundaries, but when we have multiple checks we need to quit on the first error.

add tests for the type block

bail out of client_read if we've already decide what to do libevent2 can still somehowe call client_read even in code paths that never enable reading from the evbuffer. Can't reproduce on the libevent in base on OpenBSD. It's a bit ugly, but it's a small workaround for something that otherwise *always* make gmid crash when linked against libevent2. (client_read works under the assumption that c->host != NULL, matched_proxy crashes otherwise.)

add set_proxy to simplify testing + more checks in test_proxy_with_certs

parethesize `proxy', I'm about to change the syntax

add proxying with client certificate test

typo

add a test for the `proxy relay-to' rule

rename variable

run all kinds of tests via tests.sh/runtime while there also change the dependency in the makefile: iri_test should be alone, not as deps of `data'.

re-add sha script; it's used in the Makefile While there, use it in the tests too

rework the regression suite The tests are still there, the suite is equivalent to the old one, but this one is better structured. The biggest annoyance I had with the old one was that it wasn't straightforward to test only a specific set of tests. It's still impossible, but it's way easier to do it now. This extract all the tests to their own functions. It's overall better in all possible regards.
