- sockmapping rewritten from stratch to minimilse polling. poll() is now
only called if blocking is actually expected, splice pipes are now
polled if splice fails, buffers flushing is much more accurate.
- logging code moved to separate files
- signal masks added to client threads to prevent unneeded interruptions
- bandwidth limitation will not delay the thread after client or server
shutdown
Supports _real_ name resolution via parent proxy over TCP in nserver /
dnspr.
Can be used to create UDP->TCP name proxy, e.g.
nserver 127.0.0.1/tcp
nscache 65535
auth none
dnspr
auth iponly
tcppm 53 77.88.8.8 53
now, all names are resolved via TCP connection to 77.88.8.8
(dns.yandex.ru).
