Every class must have a unique attribute that will be used
to instantiate the object. The value provided for this
attribute must be unique within the same alsaconf node for
objects of the same class. Add a helper function to get the
name of the attribute that must have a unique value in the
object instance.
For example, when instantiating 2 buffer widgets within a pipeline,
they must be given unique instance attribute values as:
Object.Widget.buffer.0{} and Object.Widget.buffer.1{}.

Add helper functions to check if an attribute is
mandatory, immutable or unique in the class definition.
ex: for a host widget component, these are defined
as follows:
attributes {
#
# host objects instantiated within the same alsaconf node must have unique
# direction attribute
#
unique "direction"
mandatory [
"type"
"stream_name"
]
immutable [
"uuid"
]
}

Add a helper function look up attribute definition in the
"DefineAttribute" config in the class definition.

Add a helper function to look up the class definition for
an object. ex: for an object instance, Object.Widget.pga.0{}, the
function returns the config pointing to Class.Widget.pga{} in
the input conf.
