The compile warnings at filling MIDI stream name strings are all
false-positive; the number of streams can't go so high.
For suppressing the warning, replace snprintf() with scnprintf().
As stated in the above, truncation doesn't matter.

ALSA driver for TASCAM FireWire series transfers MIDI messages in system
workqueue. In current design of the driver, applications should wait for
sequence of transmission when they close ALSA rawmidi character devices.
However, when considering design of rawmidi interface, it's preferable
to wait in drain ioctl.
This commit adds support for the drain ioctl to wait for the end of
the transmission.

Units on TASCAM FireWire series handle MIDI messages with support for
running status. Drivers for the series should remember current running
status and transfer valid MIDI messages. For this purpose, current
ALSA driver for the series has some members in its top-level structure.
This is due to better abstraction of async midi port. Nowadays, the
abstraction was localized just for the driver.
This commit moves the members to structure for async midi port.

In current design of ALSA driver for TASCAM FireWire series, initialization
of members in asymc midi port structure is done at device probing. Some of
the members should be initialized every time to use rawmidi devices because
they're changed in sequence of transmission for MIDI messages.
This commit adds a new function to initialize them. Invariant parameters
during object lifetime are kept as is.

Now snd_rawmidi_ops is maintained as a const pointer in snd_rawmidi,
we can constify the definitions.

Some identifiers are referred just by one functions. In this case, they
can be put into the function definition. This brings two merits; readers
can easily follow codes related to the identifiers, developers are free
from name conflict.
This commit moves such identifiers to each function definition.

In former commits, this driver got functionalities to transfer/receive
MIDI messages to/from TASCAM FireWire series.
This commit adds some ALSA MIDI ports to enable userspace applications
to use the functionalities.
I note that this commit doesn't support virtual MIDI ports which console
models support. A physical controls can be assigned to a certain MIDI
ports including physical and virtual. But the way is not clear.
