It seems pointless to accumulate "late" connection attempts.

I don't think it makes sense to ever package it separately from kresd,
so why should it have separate versioning? (could be confusing)

On 32-bit systems the insufficient GC could commonly happen:

The meaning of -f parameter got slightly changed, so that the buggy
computation could be greatly simplified.  GC seems to make sense when
most of cache space is used, in which case the difference is small.

There were the usual effects: very incorrect timestamps (even by days),
and I suspect we could even lose some logs completely.

Fixes #582.

Trie relies on __attribute__(cleanup) and if its missing, it could
lead to memory leaks such as:

daemon/tls: send fatal error on failed handshake

See merge request !1007

If the TLS handshake process fatally fails (e.g. no matching cipher
suite / cert), sent an alert to notify the peer.

modules/hints: NODATA answers also for non-address queries

See merge request !1005

The fact that it's not a real separate RCODE
is always complicating stuff.

Also avoid using non-local variables.
