46c67fe070 Portability fix for alsa-lib on mips 
From: Henryk Plötz <henryk@ploetzli.ch>

I recently had problems building alsa-lib 1.0.10 on mips (for my
Netgear WGT634U). Turned out the problem was in include/alsa-symbols.h
were there was __asm__ code that wouldn't work with the mips assembler.
Attached is a patch that makes this work again.

551c22fcb8 seq: reorganize sequencer client numbers 
Reduce the maximum possible number of global clients to 16 to make
more numbers available for card clients, and allow dynamically allocated
card client numbers to share the same range as application client
numbers to make sure that all 32 cards can be used at the same time.

ce67d5389b more simple mixer - basic abstraction - work 
- midlayer cleanups and simplification
- probably broke the "none" abstraction code somehow (not intensively tested
  midlayer changes)
- trying to implement ac97 module
  - far from finished
  - common code should be moved to alsa-lib as core for other modules
  - perhaps simple_abst.c can be based on this common code, too

597b4d0942 big simple mixer update 
- exported all necessary functions to create a mixer module outside alsa-lib
- separated simple mixer API from the simple mixer implementation
  (using callbacks as usuall)
  - src/mixer/simple.c is the core
  - src/mixer/simple_none.c is the current (no-abstraction) implementation
    based on control names; note that this module does not depend on
    internal ALSA structures now
  - src/mixer/simple_abst.c is the ongoing abstraction which will use
    external dynamic modules; src/conf/smixer.conf will describe which
    modules will be used depending on the components from the driver

4d7c53d280 Add snd_pcm_hw_params_get/set_export_buffer() 
Add snd_pcm_hw_params_get/set_export_buffer() API functions.

Otherwise the buffer can be handled only locally (no shm).

Also fixed Version file for 1.0.9.
