umh: Rename the user mode driver helpers for clarity

Browse Source 
Now that the functionality of umh_setup_pipe and
umh_clean_and_save_pid has changed their names are too specific and
don't make much sense.  Instead name them  umd_setup and umd_cleanup
for the functional role in setting up user mode drivers.
