gen_tempname. TMPL is overwritten with the result.

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. */
