[ITP-adopt] stunnel-4.20-1

[Schulman dot Andrew at epamail dot epa dot gov]

stunnel was abandoned for Cygwin back in the fall.  I've packaged the
latest version for Cygwin (URLs below) and would like to maintain it.

stunnel is a program that allows you to encrypt arbitrary TCP
connections inside SSL (Secure Sockets Layer).  stunnel can allow you to
secure non-SSL aware daemons and protocols (like POP, IMAP, LDAP, etc)
by having stunnel provide the encryption, requiring no changes to the
daemon's code.

Changes since the last Cygwin release:
- updated to version 4.20
- moved stunnel executable from /usr/sbin to /usr/bin, to comply with
the Linux Filesystem Hierarchy Standard
- added cygstunnel.dll
- changed to cygport build method
- new Cygwin maintainer

Please note that, although libstunnel.so (i.e. cygstunnel.dll) is
included in this package (as Corinna requested back in October;
http://www.mail-archive.com/cygwin-apps@cygwin.com/msg17175.html), its
use is undocumented AFAICT and so I haven't tried to test it.  I guess
that something like LD_PRELOAD=/usr/bin/libstunnel.dll should provide
transparent proxy support for clients via stunnel, but I don't really
know how or if it would work.  If people want me to leave that in so
they can test it, fine.  If not, fine too and I'll take it out.

Please review and, if the package is found suitable, upload.

Thanks,
Andrew.
