r7072: moved the esp hooks calls to the ejs level, so we can call them from
both esp scripts and ejs scripts. This allows the smbscript program to
call all the existing extension calls like lpGet() and ldbSearch()

Also fixed smbscript to load smb.conf, and setup logging for DEBUG()

I left the unixAuth() routine in web_server/calls.c at the moment, as
that is really only useful for esp scripts. I imagine that as we
extend esp/ejs, we will put some functions in scripting/ejs/ for use
in both ejs and esp, and some functions in web_server/ where they will
only be accessed by esp web scripts
