The path is not an absolute path and can't be used with `access()`.
Let's call `uc_mgr_config_load_file()` directly and mask acceptable
error numbers.

Since glibc-2.43:
For ISO C23, the functions bsearch, memchr, strchr, strpbrk, strrchr,
strstr, wcschr, wcspbrk, wcsrchr, wcsstr and wmemchr that return pointers
into their input arrays now have definitions as macros that return a
pointer to a const-qualified type when the input argument is a pointer
to a const-qualified type.

Add bool show_err parameter to uc_mgr_get_variable() to control whether
an error message is displayed when a variable is not defined. This
centralizes error reporting and eliminates redundant error messages
in callers.

Add variable support for all lookup arguments in find-card and find-device
substitutions. Variables are identified by $ prefix and only enabled for
Syntax 9+ to maintain backward compatibility.
Modified arguments with variable support:
- find-card: field, regex
- find-device: type, field, stream, regex
Example usage:
${find-card:field=$FieldName,regex=$Pattern,return=number}
${find-device:type=$DevType,stream=$StreamType,field=$FieldName,regex=$Pattern}

Implement ${info-card:} substitution to retrieve specific fields from
a card's information structure by card number or ID. Unlike ${find-card:}
which searches through cards using regex, ${info-card:} directly queries
a specific card.
Arguments:
card=<STR> card number or card ID (string identifier)
field=<STR> number, id, driver, name, longname, mixername, components
Allow card and field parameters to reference UCM variables by prefixing
with $ character. When the first character is $, the value is resolved
using uc_mgr_get_variable().
Example usage:
${info-card:card=$MyCard,field=$MyField}

When If.Condition is a string type instead of compound, parse it using
snd_config_load_string with variable substitution support for syntax v9+.
This allows more flexible condition definitions using variable references.

Refactor if_eval_string() to eliminate code duplication by introducing
a compare_strings() helper function that handles the common pattern of
retrieving, substituting, and comparing string pairs.

Adds support for integer comparison operations in If.Condition blocks.
Supports operators: ==, !=, <, >, <=, >= for comparing integer values.
Both values are substituted and converted from strings to 64-bit integers.
Hexadecimal (C like) strings are also accepted (like 0x1234).
Example usage:
If.check_channels {
Condition {
Type Integer
Operation ">"
Value1 "${var:channels}"
Value2 "2"
}
True { ... }
}

It is useful to substitute the variable names and string
macro arguments. It may simplify the UCM configurations.
E.g.:
Define."${var:Name} Suffix" "Value"
Macro.a.DoIt "Channels=${var:PlaybackChannels}"

The 'amixer controls' and 'amixer cget numid=' combo was not working
correctly when the remapping was active. This assert was trigerred:
amixer: control.c:427: snd_ctl_elem_info: Assertion `ctl && info && (info->id.name[0] || info->id.numid)' failed
All elements must be loaded and mapping created to build

Unfortunately, the case when the old application sets
own error callback using the old method, was not handled
properly in snd_lib_vlog_default() function.
Make sure that only error messages are passed to this
old callback and silent other log priorities.
