The 63f7745b commit is loading the driver specific configuration
multiple times which ends with the array merges (see the bug).
Introduce the loaded compound which traces the already loaded
driver configurations and skip the multiple load requests.

Fixes:
cd alsa-lib
if test -r Makefile; then
make distclean
fi
mkdir build
cd build
../configure
make
Note:
The srcdir is used for the symlinks to generated include files :-(
I've not found a better (easy) way to fix this.

Allow to save whole (or partial) local UCM alsa library configuration
to a file.
Syntax (saves key1.key2 sub-tree):
Sequence [

The /var/lib/alsa/card<CARDNO>.conf.d configurations are loaded
to the cards.<CARDNO> tree only (overwrite mode).

There's an issue with the current code: It says append for compounds,
but it does overwrite without the proper members delete from
the overwritten (destination) compound node.
Don't change the behaviour, just fix the comment and memory leak.

This change renames the original exec command to shell which
is more appropriate. Implement a light version of the exec
command which calls directly the specified executable without
the shell interaction (man 3 system).

The change device definitions (pcm.front etc.) from the driver
roots (cards.<DRIVER_NAME>) to the card number roots (cards.<CARDNO>).
This will allow us to do custom overrides (like UCM) in
/var/lib/alsa/card<CARDNO>.conf.d.
For dmix and dsnoop default values, use the card ID instead
the card driver name. It's more flexible.

For the per-card configuration, add possibility to define
card number -> card driver link table.
Example:
cards.0 'cards.USB-Audio'
cards.1 'cards.USB-Audio'
cards.2 'cards.HDA-Intel'
cards.3 'cards.USB-Audio'

Fix the "Capture Volume" and "Capture Switch" exceptions no longer
working after commit 86b9c67774 ("mixer: simple - Unify simple_none:
base_len() exception handling") because they were moved to after the
suffix checking, so they would be treated as CTL_GLOBAL_VOLUME resp.
CTL_GLOBAL_SWITCH based on their suffix before the exception check
has a chance to check for a match.

When the user requests to ignore sysfs write errors by prefixing
the path with a '-' then we need to skip the '-' when building the
actual path otherwise the write will never work.
