Added snd_config_hook_load_for_all_cards.

Added private_data parameter for snd_config_hooks function.
Fixed the return value mess in the config parser routines.
The include file could begin with 'confdir:' which is replaced with /usr/share/alsa.
The snd_config_search_definitions looks for raw name at first (without suggested root).
Added snd_func_private_card_strtype function.
All configuration files moved to the src/conf directory.
Configuration files modified to use load-on-demand feature using hooks.
