Bounded quantity semaphore in which the resource is acquired and released in units of one, but with a maximum amount of units available at any given time.

Build a new BQSem with supplied initial and maximum supply. An exception is thrown in any of the following cases:

• Initial supply is negative.
• Maximum supply is less than 1.
• Initial supply exceeds maximum.

Wait for a unit to become available.

Make a new unit available, unless the maximum number of units has been reached, in which case it does nothing (it doesn't block).

Get current supply quantity.
