The pthread_mutexattr_t object should be destroyed by calling
pthread_mutexattr_destroy(), otherwise it may cause a potential
memory leak due to the different implement of pthread_mutexattr_init()

We have a requirement to "hide" some hardware drivers, because
other (main) UCM configuration will refer them.

This error code can be used e.g. with echo reference PCM devices
(the SND_USE_CASE_MOD_ECHO_REF UCM token).

In commit b906db19ef, the snd_dlopen()
implements the automatic lookup to the ALSA_PLUGIN_DIR directory.
It is not necessary to add the absolute paths in callers now.
The plugin names are also searched in ld.so.conf paths as the fallback now,
but it should not be a big problem.

Include $XDG_CONFIG_HOME/alsa/asoundrc _or_ ~/.config/alsa/asoundrc as
the last user-defined configuration.

While I was trying to work on XDG_CONFIG_HOME support, I though
that it may be nice to support OR for the file specification.
But then I found that we can already do this via the refer hook.
I commit this change anyway, because the snd_config_hook_load()
function is more clean now.
The OR is implemented with three | characters like:
"~/.asoundrc|||~/.asoundrc2|||/opt/some/other/path"
(first file found wins)

once draining is done, the pcm enters the SETUP state, which ought to
be valid for snd_pcm_drain()

The syntax is ${CardIdByName:CARDNAME[#INDEX]}.
The CARDNAME is the ALSA's soundcard name (short form).
The INDEX is the instance (0 = first, 1 = second etc.).
Example: ${CardIdByName:HDA Intel PCH}
(which is identical to ${CardIdByName:HDA Intel PCH#0})

There is a big issue to validate all possible configuration paths.
Let create ucm2/ucm.conf file which describe the lookups. It may
be also customized later to follow the kernel-side development.

Syntax:
DefineRegex.VariableName {
String "something to match"
Regex "(me)thi(ng)"
}
Result:
- configuration variable "VariableName" is equal to "mething"
- configuration variable "VariableName1" is equal to "me"
- configuration variable "VariableName2" is equal to "ng"
Notes:
The "Flags" string in the DefineRegex compound may specify
the compilation flags (e = extended, i = ignore case,
s = no substitutes, n = newline). See 'man 3 regex' for
more details.

It may be useful for the library files to use the runtime configuration
variables.
Example:
Define.Var1 "hw:${CardId},2"
Value.PlaybackPCM "${var:Var1}"
