Finish WaitQueue, ErrorQueue; add util.count(), join(); extend qtest.
For WaitQueue, nail down the mechanism for declaring a subclass and for
calling a base-class method from a subclass override. Break out new
_wake_waiters() method from Enqueue(): we need to do the same from close(), in
case there are waiting consumers. Also, in Lua, 0 is not false.
Instead of bundling a normal/error flag with every queued value, make
ErrorQueue overload its _closed attribute. Once you call ErrorQueue:Error(),
every subsequent Dequeue() call by any consumer will re-raise the same error.
util.count() literally counts entries in a table, since #t is documented to be
unreliable. (If you create a list with 5 entries and delete the middle one, #t
might return 2 or it might return 5, but it won't return 4.)
util.join() fixes a curious omission from Luau's string library: like Python's
str.join(), it concatenates all the strings from a list with an optional
separator. We assume that incrementally building a list of strings and then
doing a single allocation for the desired result string is cheaper than
reallocating each of a sequence of partial concatenated results.
Add qtest test that posts individual items to a WaitQueue, waking waiting
consumers to retrieve the next available result. Add test proving that calling
ErrorQueue:Error() propagates the error to all consumers.
