valgrind handles floating point numbers differently for some reason, so using "simpler" numbers to make tests happy.

string to number API is now more strict not accepting spaces before or after the number. A few tests converted to match the new error messages using the word float instead of double.

new tests for EXPIRE family functions, new millisecond precision, and new millisecond argument variants.

Redis.call is now split into two variants of the same function. Redis.call will raise an error by default. Redis.pcall will return the error object instead.

Redis test ports selection made more robust. This prevents the test from hanging if an already bound port is selected but the TCP server listening to it does not cause a protocol error with a Redis client PING. Also base port moved away from the range near to the Redis Cluster gossip ports.

implemented --single, --list-tests. --accurante and --help are now recognized but not actually implemented.

no longer prints testing... but just shows the test when we get the final result from the testing client.
