Log Message:
Update to 1.17. Add dependencies on p5-Net-LibIDN and p5-IO-Socket-INET6
for IDN and inet6 support.

v.17 2008.10.13
- no code changes, publish v.16_3 as v.17 because it looks better
  than v.16
- document win32 behavior regarding non-blocking and timeouts

v.16_3   2008.09.25
- fix t/nonblock.t with workaround for problems with
  IO::Socket::INET on some systems (Mac,5.6.2) where it cannot do
  nonblocking connect and leaves socket blocked.
- make some tests less verbose by fixing diag in t/testlib.t
  (send output to STDOUT not STDERR and prefix with '#')

v.16_2   2008.09.24
- work around Bug in IO::Socket::INET6 on BSD systems
  http://rt.cpan.org/Ticket/Display.html?id=39550
  by setting Domain based on PeerAddr
  Thanks to srezic for report and support
- remove tests of recv/send from t/core.t. Might badly interact
  with SSL handshake and cause crashes as seen on OS X 10.4

v.16_1   2008.09.19
- better support for IPv6:
  - IPv6 is enabled by default if IO::Socket::INET6 is available
  - t/inet6.t for basic tests
