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

• rework hash table interna to avoid gcc-4.1 on Debian etch bug • also improve behaviour with _a lot_ (>2²⁸) entries • while here, improve comments and whitespace
