Log:
[KS]
- Implement IKsDevice::GetAdapterObject, IKsDevice::ArbitrateAdapterChannel
- Store device interface guid in the symbolic link list entry, which is used by
KsFilterFactoryUpdateCacheData
- Implement KsFilterFactoryUpdateCacheData, which is used to dynamically propagate format
/ medium changes to directshow components
- Move stream pointer preparation to an own function, which is called by
KsPinGetLeadingEdgeStreamPointer / KsStreamPointerClone / KsStreamPointerAdvanceOffsets
- Fix locating correct offset in KsStreamPointerScheduleTimeout,
KsStreamPointerCancelTimeout, KsStreamPointerGetNextClone
- Further BDA support is on hold until ReactOS supports s/g in hal
