Show listening port number in startup log message.

Include more details in --version output: say whether symlinks and
hardlinks are supported.
When hardlink support is missing, explain whether the problem is on

Automatically build included libpopt if there is none on the system,
or if --with-included-popt is specified.
Add --enable-debug.
