The global winbind file descriptor can cause havoc in some situations -
particulary when it becomes 0, 1 or 2. This patch (based on some very nice
work by Hannes Schmidt <mail@schmidt-net.via.t-online.de>) starts to recitfy
the problem by ensuring that the close-on-exec flag is set, and that we move
above 3 in the file descriptor table.
I've also decided that the PAM module can close it's pipe handle on every
request - this isn't performance-critical code.
The next step is to do the same for nss_winbind. (But things like getent()
might get in our way there).
This also cleans up some function prototypes, puts them in just one place.
