/* Generate a temporary file name based on TMPL.  TMPL must match the
   rules for mk[s]temp (i.e. end in "XXXXXX").  The name constructed
   does not exist at the time of the call to gen_tempname.  TMPL is
   overwritten with the result.

   KIND may be one of:
   GT_NOCREATE:         simply verify that the name does not exist
                  at the time of the call.
   GT_FILE:       create a large file using open(O_CREAT|O_EXCL)
                  and return a read-write fd.  The file is mode 0600.
   GT_DIR:        create a directory, which will be mode 0700.

   We use a clever algorithm to get hard-to-predict names. */
