ALSA: seq: Notify UMP EP and FB changes
So far we notify the sequencer client and port changes upon UMP FB
changes, but those aren't really corresponding to the UMP updates.
e.g. when a FB info gets updated, it's not notified but done only when
some of sequencer port attribute is changed. This is no ideal
behavior.
This patch adds the two new sequencer event types for notifying the
UMP EP and FB changes via the announce port. The new event takes
snd_seq_ev_ump_notify type data, which is compatible with
snd_seq_addr (where the port number is replaced with the block
number).
The events are sent when the EP and FB info gets updated explicitly
via ioctl, or the backend UMP receives the corresponding UMP
messages.
The sequencer protocol version is bumped to 1.0.5 along with it.

ALSA: rawmidi: Show substream activity in info ioctl
The UMP legacy rawmidi may turn on/off the substream dynamically
depending on the UMP Function Block information. So far, there was no
direct way to know whether the substream is disabled (inactive) or
not; at most one can take a look at the substream name string or try
to open and get -ENODEV.
This patch extends the rawmidi info ioctl to show the current inactive
state of the given substream. When the selected substream is
inactive, info flags field contains the new bit flag
SNDRV_RAWMIDI_INFO_STREAM_INACTIVE.
