rpcrt4: Dereference the pointer passed to the marshaling/unmarshaling/sizing routines in complex types for interface pointers.

rpcrt4: Set PointerBufferMark to the buffer location immediately after the non-pointer data in complex struct and array marshaling and unmarshaling to keep to the DCE/RPC specification.

rpcrt4: Try a lot harder to resuse existing connections by comparing inside the RpcQualityOfService and RpcAuthInfo objects.

Store a copy of the SEC_WINNT_AUTH_IDENTITY structure passed in to
RpcBindingSetAuthInfo(Ex) to enable us to do this for RpcAuthInfo objects.

rpcrt4: Store the assoc_group_id field returned from the bind_ack packet and use it when creating further connections in the association group.

rpcrt4: When an exception is raised, return the stored exception code instead of the generic RPC_S_CALL_FAILED.

rpcrt4: Translate STATUS_ACCESS_VIOLATION exceptions caught whilst executing the stub function to ERROR_NOACCESS to prevent confusing exceptions occurring in the client.

rpcrt4: Close the connection if a protocol error or certain other kinds of errors occur, instead of returning it to the connection pool.

rpcrt4: Don't use add on the sizes of array elements to an open-ended structure; use FIELD_OFFSET with the array index instead.

advapi32: Always set the requested fields of the security descriptor according to the info flags in GetNamedSecurityInfoW.

Also, set the control flags so that other security descriptor
functions can retrieve the info from it.

mshtml: Notify the Gecko stream listener that we stopped binding, if an error occurs in start_binding.
