Summary: patch for native alsa sequencer midi support

Initial Comment:
The patch allows pd to be connected to different
sources and sinks of midi messages through the alsa
sequencer natively.
It lets pd open 1 or more sequencer inputs or outputs.
Alsa midi support is selected at compile time, if alsa
headers are found  alsa midi support will be compiled
instead of oss. 
All midi events work ok, i think probably raw midi does
not.

reopened!

attached is an improved version of the alsa-sequencer
support, that automatically connects each available device
to/from pd.
(note: currently it only connects if pd opens just 1 port)
this eliminates the need for "external" helpers, like the
[aconnect]-external, aconnect, aconnectgui or qjackctl

furthermore i found and fixed some, namely reverting the
number of in and out devices.

Hmm, I can't find Guenter's fix... did it really get uploaded?

implemented a first version of runtime switching between
OSS-midi and ALSA-midi.
i haven't made all the various APIs switchable (as is with
audio), because it deemed me too much work...

replaced s_midi_alsa.c with steve's version;
this allows more than 1 MIDI output-port (or device) (read:
more than 16 channels) and fixes [midiout]

i did a little tweaking of this patch and right now it works
on all 8 ports of my midisport8x8, plus sys_putmidibyte is
implemented, so [midiout] actually triggers midi instead of
an error message.  it's a bit of a hack job, but it works
great for me (and hopefully you as well).

my modified version of s_midi_alsa.c can be found at
http://finkla.com/steve/s_midi_alsa.c
if anyone with power to update the files here on sourceforge
cares to, please do, but in any case that link should stay
alive for quite a while.

I didn't look closely, but I think to do this right would
require
actually giving a run-time choice between ALSA and OSS MIDI
systems.  A big job.

Here is the patch and s_midi_alsa.c file as I use it in the
Debian package currently. It seems that the author  of the 
patch does  not have to time to update it, or probably he
just isn't aware of problems, so take it with a grain of
salt. Also we have to check for the multiple devices problem
steve.long
mentions.

apparently [notein] for channels above 16 works as expected,
17-32 coming from the second device and so on, but [noteout]
only sends to the first device, chans 17-32 send to device 1
just like 1-16, as do 33-48, etc.

this crashes my system if i don't have an alsa-sequencer
(e.g. no modules loaded)

there is a bug when no alsa devices are present (or if
they can't be opened). Attached addon patch fixes the problem.
