OSS improvements patchset

So here's a patchset which works for me. I used your suggestion of just caching
the largest bi.bytes value as the max buffer size, and calculating the amount
of data in the OSS buffer based off of that. It works in the handful of cases
that I've tried, and passes your extended render tests (with WINETEST_DEBUG=2)
just fine. Now it works basically the same as the ALSA driver (writing in
period-sized chunks, no more than 4 periods in the OSS buffer, no writing in
ReleaseBuffer, etc).
