Patch info for stdin_confpatch_bri

Author Comments

This patch allows you to provide the Stunnel configuration file
on stdin or on any arbitrary file descriptor.

  stunnel -conf_stdin		# take the configuration from standard input

  stunnel -conf_fd=#		# take the configuration from file
                                   descriptor number "#"


This allows you much greater flexibility, in that you can
generate dynamic stunnel configurations on the fly without
resorting to temporary stunnel.conf files.

I'm debating if I should make it possible to have the config
file on stdin work in non-daemon mode.  For example, with the
a file such as this:

        client = yes
        pid =
        connect = www.example.com:443

you'd be able to run stunnel like this:

        $ stunnel stunnel.conf
        GET / HTTP/1.0             <== typed by you.
                                   <== typed by you.
        HTTP/1.0 200 OK            <== returned by remote
        ....
        
and have your stdin and stdout connected to the remote end.  If you
use 'stunnel -conf_stdin' this is not possible, because the config
file (stdin) is closed after being read.

The only way I can think to get around this is by instead using
-conf_fd= instead, or by modifying the patch to create some new
config option that says 'config ends here' and makes sure that
it leaves the file descriptor open.  I'm not too pleased with
that second option.
