Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

3 * Routines for control of 16-bit SoundBlaster cards and clones
4 * Note: This is very ugly hardware which uses one 8-bit DMA channel and
5 * second 16-bit DMA channel. Unfortunately 8-bit DMA channel can't
6 * transfer 16-bit samples and 16-bit DMA channels can't transfer
7 * 8-bit samples. This make full duplex more complicated than
8 * can be... People, don't buy these soundcards for full 16-bit
9 * duplex!!!
10 * Note: 16-bit wide is assigned to first direction which made request.
11 * With full duplex - playback is preferred with abstract layer.
12 *
13 * Note: Some chip revisions have hardware bug. Changing capture
14 * channel from full-duplex 8bit DMA to 16bit DMA will block
15 * 16bit DMA transfers from DSP chip (capture) until 8bit transfer
16 * to DSP chip (playback) starts. This bug can be avoided with
17 * "16bit DMA Allocation" setting set to Playback or Capture.
