make tmux hack workable for now (libtermcap is… ugly) • track $TERM for the types tmux uses /^screen(-.*)?$/ • when tmux is in use (or GNU screen, really), use the, now hardcoded, clear-to-EOL string; otherwise, use the old behaviour • drop unnecessary x_e_rebuildline() carefully tested to behave no worse than R52b

further optimise and simplify the handling of $RANDOM, reads and writes to it are now either arc4random or rand/srand, but srand retains the old state; set +o arc4random is no longer possible, but if it's there we use arc4random(3), if not, we use rand(3) for $RANDOM reads; optimise special variable handling too and fix a few consts and other minor things
