bioq - Add a sysctl kern.bioq_barrier to control bioqdisksort()'s sorting.

Control how well sorted we want bioqdisksort() to be.  The value specified
in kern.bioq_barrier is the number of bio's that will be sorted until a
barrier is inserted, starting a new set.  The default value is 16.

This allows testing filesystem throughput under varying conditions.
