AWARE: Abstract structure of match filters

Replace byte[] representation with a List<byte[]> representation
which abstracts the LV (TLV without a type field) structure of
the match filters.

Tlv utilities: remove tag indicating that will be made public API.
That is no longer expected (will be an internal utility) since the
match filter structure is now parsed when exposed to API.

Lv utilities: removed. Was a simple wrapper around Tlv utilities -
no longer needed since will not be exposed as API.
