[PATCH 0/1] MR9111: ws2_32: Implement SIO_BSP_HANDLE_SELECT.

[Josh Steffen (＠joshsteffen)]

My understanding is that, in the absence of layered service providers, `SIO_BSP_HANDLE_SELECT` should behave like `SIO_BASE_HANDLE` (this is relied upon by https://github.com/python-trio/trio). Should I add tests to verify this? If so, should they basically just be the same as the existing `SIO_BASE_HANDLE` tests?

[PATCH 1/1] ws2_32: Implement SIO_BSP_HANDLE_SELECT.

From: Josh Steffen

Wine does not support layered service providers, so just fall through to
SIO_BASE_HANDLE.

Yes, please.
