We need to define the common shared configuration like for multiple
HDMI devices or so. Substitute the whole merged configuration tree
including identifiers.

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})

Condition {
Type ControlExists
Control "name='Capture Input'"
ControlEnum "Headphone Mic"
}
The result is true if the control exists, it is the enumerated
type and has the item with the ControlEnum text (name).

Because of the nature of the structured parser, it is not guaranteed
that the order of the parsed tree is equal to the lines in the source.
Add possibility to insert the If results before or after the selected
identifier like:
SectionDevice."Speaker" {
...
}
If.1 {
Condition { ... }
Before.SectionDevice "Speaker"
True { ... }
}
If.2 {
Condition { ... }
After.SectionDevice "Speaker"
True { ... }
}
If the "After" or "Before" identifiers are not found, the result is added
after the last entry in the block.

The syntax is simple:
If./any-if-identificator/ {
Condition {
Type /type_here/
/optional defines/
}
True {
/block used when condition is evaluated as true/
}
False {
/block used when condition is evaluated as false/
}
}
The Type "ControlExists" is implemented:
Condition {
Type ControlExists
Device "hw:${CardId}"
Control "iface=CARD,name='Headphone Jack'"
}
