snd_config_add() checks for duplicate ids, but it was possible to create
duplicates by adding a note and changing the id afterwards with
snd_config_set_id(); so we have to add a check there, too.

Make sure that we do not crash when encountering configuration nodes
with a NULL id. Furthermore, since we cannot avoid having NULL ids
anyway, allow the id of a top-level node to be reset to NULL.

The variable $ALSA_CONFIG_PATH specifies the config path, but the current
code accepts the empty string and results in a mysterious error because
no config file is found.
This patch fixes the check of the variable and takes the default value
if the string is empty.

Added --with-configdir and --with-plugindir options to configure
which specify the directories for config files and plugin objects
respectively. The default paths when these options are not
specified are unchanged.
- add snd_device_name_hint() and snd_device_name_free_hint() functions
- add snd_ctl_iface_conf_name() functions
- do not accept parameters for the plugin definition without @args section
- add defaults.pcm.dmix.card/device and dsnoop.card/device definitions
- add hints for HDA-Intel.conf, pcm/dmix.conf, pcm/dsnoop.conf and alsa.conf
- add test/namehint test utility
- doxygen related cleanups
safe_strtoll() now accepts numbers in any base. It formerly assumed that
its input was a decimal number, which had the consequence that
hexadecimal or octal numbers would be parsed as strings when occurring
outside of parameter lists.
This obsoletes some workarounds in the file permission parsing code that
relied on this bug.

Freeing the global config update structure when it had been created
without any configs present caused an assertion to trigger. Since this
is a valid scenario and the assertion didn't really protect against
anything, it should simply be removed. Attached patch does exactly that.
Fixed problem with EOF detection in freestring parser.
Fixed problem with run-time argument parsing (snd_config_load()->snd_config_load_override() replace).
Added more documentation for configuration run-time arguments and hooks.
Fixed the behaviour of snd_config_search_definition() - implicit and explicit base.
- changed snd_config_get_id function to follow semantic of other get functions
- added snd_config_test_id
- added runtime pointer type (not persistent)
- added snd_config_make_pointer, snd_config_set_pointer, snd_config_get_pointer
- added type/contents checking for callback functions
- changed 'void *private_data' to 'snd_config_t *private_data'
- renamed card_strtype functions to card_driver
Control:
- fixed passing parameters to snd_ctl_async
Async handlers:
- added public snd_async_handler_get_signo function
Documentation:
- moved all documentation to source files
