Makefile: remove test python files from dependencies

This means we don't have to regenerate everything when we change the tests.
pyloxi: unpack of_list_bucket_t
pyloxi: blacklist inheritance parents from simple list deserialization

All inheritance hierarchies need special list processing.
pyloxi: unpack of_list_group_desc_stats_entry
pyloxi: unpack of_list_group_stats_entry
openflow_input: add missing table_stats_request/reply messages to OF 1.3
pyloxi: support meter bands
pyloxi: unpack of_list_meter_stats
pyloxi: implement of_meter_features_t
pyloxi: generate instruction classes
pyloxi: unpack of_list_instruction
pyloxi: fix of_wc_bmap_t for OF 1.2+

This field changed semantics, so the LOXI type probably should change too.
