Follow the new definitions in the kernel side. MONO and others have
been added, and the order of position table was changed again.

mixer.h already contains some channel position definitions.
To be more consistent over all systems, better to follow the same
order for the new channel map, too. But since UNKNOWN channel must be
zero but the definition in mixer.h contains -1 as UNKNOWN, simply
shift the value with 1.
If the conversion is required between SND_CHMAP and SND_MIXER_SCHN,
just increment/decrement 1. Eventually I'll provide helper functions
for that...

Added new channel-mapping API functions.
Not all plugins are covered, especially the route, multi and external
plugins don't work yet.

Handling of user control elements was implemented for all types except
BYTES and ENUMERATED. Enumerated user controls will be needed for the
device-specific mixers of upcoming FireWire drivers.

The off_t in kernel struct (for ioctls) is actually different from the
definition of user-space off_t. The kernel off_t is equial with long
while user-space off_t depends on the large-file support.

Increase the components array size from 80 to 128 chars.
The string there is supposed to be null-terminated, so it can cover
the smaller array size in the older version, too.

Remove enum in structs from kernel API headers.
The enum is not always equivalent with int on some architectures.
From: Hans-Christian Egtvedt <hcegtvedt@atmel.com>
- this patch adds support for suspend & result for dmix and other
direct plugins
- the timer detection / initialization (TREAD support) was redesigned and
the check for proper driver version was moved to the timer_hw.c
Add snd_pcm_hw_params_get/set_export_buffer() API functions.
They control to ensure the buffer export to other processes.
If this flag is set, the local buffer of a plugin is exported over IPC shm.
Otherwise the buffer can be handled only locally (no shm).
Also fixed Version file for 1.0.9.
