Gives us the lowest HW sample rate that's >= 22KHz. Needed because some targets that don't support 22K support 11K or 8K, so HW_SAMPR_MIN will give us much lower quality than is acceptable. Take advantage of this new macro in the SDL, MIDI, and MIKMOD plugins, and implement a crude "fast enough" test to enable higher sample rates on more capable targets.
