getuduser - return user database entry of Unidata user

       This function returns the user database entry for the Unidata user -- or NULL if no such user exists.  It
       tries the UNIX function `getpwnam()' with a series of user names and stops at the first valid entry.  The
       first  name  tried is the value of the environment variable UDLOGNAME, if it exists.  The remaining names
       are, in order, "unidata", "ldm4", and "ldm".

       UDLOGNAME   Contains the name of the Unidata user.
