Improve the cert_*() interface. Use the return value to tell whether
the request is pending (waiting for an async event) or not. Success
or failure is always reported through the callback function.

add check-fcrdns builtin filter

ok eric@

no longer pass rdns in all filtering requests, they can be retrieved from
the filter session.

add client and listener address, as well as client rDNS and FCrDNS lookup
result to the filter_session structure upon filter session allocation. it
will allow me to simplify all filter hooks.

Use correct RFC 3464 specified values for Action field in a DSN.
error -> failed
success -> delivered

This fixes DSN parsing for Mailman. Issue reported by Cristiano

While here, rename enums to reflect the intent and properly handle
envelope ascii load/dump to understand change in the values.

Refactor certificate initialization and verification.
Factorize code duplicated in smtp_session.c and mta_session.c
Implement a simple callback interface, with proper request management
and simplified imsg protocol.

Only add the necessary parts for now.
Exisiting code path will be adapted later.

link-connect event report had an empty fcrdns field, but now that eric@ has
plugged fcrdns in the smtp_session we can fill the field with a value

introduce tx-mail and tx-rcpt report events

allow passing data lines to proc filters

ok eric@

in mda variables expansions, do not consider empty strings as errors since
an empty %{sender} is really a mailer-daemon and not an error

bring the first bits of DATA filtering plumbing but bypass it for now

ok eric@

prepare for smtp-out reporting and while at it, make a few changes to the
report format

introduce FILTER_COMMIT which will allow taking a decision at DATA commit
time, unusable yet but necessary for the upcoming serie of diffs.

ok eric@

when reporting tx events, report tx id
when reporting tx commit, report data size
report tx-envelope events

only apply filter rules to filtered interfaces

check-rdns builtin filter, to be improved

bring plumbing for proc filters

ok millert@, eric@, jung@

bring plumbing for builtin filters

ok millert@, eric@, jung@

report rDNS in link connect event

pass struct sockaddr_storage instead of ss_to_text() in reporting

teach smtp process how to report smtp events to lka and teach lka how to
report these events to a proc

ok millert@

introduce K_REGEX table type and table_regex_match(), unused for now

ok eric@

allow smtpd to fork processes at startup and maintain a socketpair with
them.

ok jung@, eric@

add helper valid_smtp_response() to be used in upcoming commits

Allow to use the "tls" keyword on any relay action to force TLS, with
strict certificate validation. The "no-verify" becomes optional.
