Unfortunately, mentioned fix caused a regression for items stored in one file.
Merge the file contents after parsing not inside parsing process.

closefrom is a library function with a fallback mechanism for when the
kernel does not support the close_range syscall.
Also check for the function properly instead of assuming it is available
with _GNU_SOURCE defined.

BootCardGroup and BootCardSyncTime variables should not be listed
by default in _identifiers. Handle them differently using

Modify verb_dev_list_check() to ensure all devices in a conflicting or
supported group reference each other. Previously, the function only
ensured bidirectional relationships. Now it ensures all devices in
the same group have complete dependency lists.

We need a boot synchronization for multiple UCM cards where linking
is expected like AMD ACP or Intel AVS drivers. This method is
using a timestamp file which can be created and modified during
the boot process (e.g. from the alsactl tool).
The goal is to return a valid UCM configuration for standard
applications combining multiple ALSA cards into one UCM configuration
and cover the time window when all cards have not been probed yet.

Ensure the SND_CTL_TLV_DB_GAIN_MUTE value is returned when the calculated
gain equals the minimum dB value for the SNDRV_CTL_TLVT_DB_MINMAX_MUTE type.
The previous check based solely on the volume value could miss cases where
the linear calculation resulted in the minimum gain.

It is necessary to reset the state logic before each verb variant
is parsed. So save the original variable list and macros and
restore them before each parser iteration.
