I just added the mktmpdir() function in serverutil.c to create this
directory.  Take a look at it and tell me if I'm missing anything
(since I'm not up on security as much as I should be)

If everything is kosher, I'll change those tmpnam calls to use this
directory.  Is there a clean way to do this other than adding another
entry to globals.h?  (I really hate globals like ASKfile and Gticket
where it's hard to figure out what the scope of the damage is going to
be if you change a call where they are involved)
