[AUDIO-BRINGUP]
- Move software bus functions into swenum.c - Add missing #undef INTERFACE in ksiface.h - Partly implement KsRemoveBusEnumInterface - Implement KsServiceBusEnumPnpRequest, KsServiceBusEnumCreateRequest, KsIsBusEnumChildDevice, KsInstallBusEnumInterface, KsGetBusEnumPnpDeviceObject, KsCreateBusEnumObject, KsGetBusEnumParentFDOFromChildPDO, KsGetBusEnumIdentifier - KS now supports the software bus driver - As a side effect, ks.sys now fully works in Windows XP - Tested with VBox+WINXP SP3+ svn path=/branches/audio-bringup/; revision=50067
