Changed lp_add/delete/enum scripts to use lockdir if spool dir doesn't
exist for printer. Rather than using pid for suffix, use a 16 byte random string. Created generate_random_str() function in genrand.c. Still needs more testing but this is the way to go. Jeremy. (This used to be commit 71a330987f990007beb16f00fc468107361b5e9d)
