  r e n a m e o n e

  Worker function to rename one file for dorenam() (below).
    old        = name of file or directory to be renamed
    new        = new name (not required for /UPPER, /LOWER, and /REPLACE)
    replacing  = 1 if doing string replacement on the name  
    casing     = 1 if converting name to lowercase, 2 if to uppercase
    all        = if doing case conversion on all names, not just monocase ones
    converting = 1 if converting character sets
    cset1      = character set to convert from (File Character Set index)
    cset2      = character set to convert to (ditto, see ck?xla.h)
    listing    = 1 to show results of rename
    nolist     = 1 to be completely silent (don't even print error messages)
    op         = 1 means simulate, 2 means check for collision, 0 means rename
    size       = length of result buffer.
    collision  = action to take if destination file already exists:
                 0 = fail
                 1 = overwrite and succeed
                 2 = skip and succeed
  Returns:
     0: on failure to rename or when a forbidden collision would have occurred.
     1: on success (file was renamed or did not need to be renamed).
  Note:
     If this code is ever built on any platform that is not Unix, Windows,
     VMS, or OS/2, this routine might need some adjustment.
