- dead SMP lock in es1968 (maestro2) driver.
Bugfix & enhances of sequencer stuff
by Scott McNab <sdm@fractalgraphics.com.au>:
- fix for the insrument list locking in SND_SEQ_EVENT_INSTR_BEGIN
and SND_SEQ_EVENT_INSTR_END events.
Note that nothing seems to really take notice of the list locking.
This is more an issue when we add support for editing instruments
anyway.
- added new alsa-lib utility function snd_seq_ev_set_varusr() which
is similar to snd_seq_ev_set_variable(), but specifies userspace
extended event data.
This is required in order to use the SND_SEQ_EVENT_INSTR_PUT
command (took me bloody ages to work this out btw)
- minor correction for gus & trident synth drivers
- snd_seq_event_output_buffer()
Outputs an event on buffer without flushing to sequencer.
Useful for non-blocking mode write.
- snd_seq_event_output_direct()
Outputs an event directly to sequencer without using buffer.
Thus the event can be passed even if output buffer is full.
- snd_seq_input_buffer_size(), snd_seq_output_buffer_size()
Returns the size of input/output buffers
- snd_seq_resize_input_buffer(), snd_seq_resize_output_buffer()
Changes the size of input/output buffers
- removed mmap control device
- reordered pcm shared and not shared code
- changed O_WRONLY oss pcm modifier in a more symmetric and elegant way
- changed slightly control interface
- added snd-debug-check
- uniformed null pointer check
- fixed a typo in linear plugin

- bugfix: proper handling of exclusive subscription
- bugfix and update: alsa-lib/test/seq* stuff
- minor updates (long option support, etc) of aconnect and aseqnet
- man pages for aconnect and aseqnet are added

- fix of memory leak in seq_midi
- snd_seq_extract_output() accepts NULL ev_res argument (for removing the
error event without malloc).
- addition of snd_seq_drain_input_buffer() and snd_seq_drain_output_buffer()
functions in alsa-lib
