Start a router DLL

Experimental, Windows only. This is intended as an alternative to Creative's
router DLL, fixing a few issues with it (falsely reporting extensions that
aren't supported, not being able to query the ALC version without a device, and
not being able to use ALC extension functions).

When enabled OpenAL Soft's DLL is built as soft_oal.dll, while the router is
OpenAL32.dll.
