param: add a new user seq field in the param-info

Browse source 
Add a new seq field in the param-info struct. Users can use this
field to keep track of pending param updates.

Store the latest seq number of the param update in the seq field. Remove
all params that don't match the sequence number because they are too
old. This avoids duplicate old params in pw-dump output.

Rework the pulseaudio manager with this same method.
