If a stream takes another stream(s) as a transport, it
always increases its reference count.  This means that
when that stream is destroyed the underlying stream is
not destroyed by default (its refcount is decreased, that's
all). To force destruction of the underlying stream,
the caller must explicitly unreference it after creating
the stream that uses it (or give its creation function
the MU_STREAM_AUTOCLOSE flag, if it supports flags).

Similarly, if a stream uses a non-stream object (e.g. a file
descriptor) as the transport, it will not destroy it, unless
it has been created with the MU_STREAM_AUTOCLOSE flag. This
differs from the previous behavior.

The MU_STREAM_NO_CHECK and MU_STREAM_NO_CLOSE flags are removed.
