- add warning note to ctnl_test.c: old API is deprecated
- split expect_api_test.c into small example files expect_*.c - introduce alias tags for original tuple attributes - introduce nfexp_sizeof and nfexp_maxsize - build expectation attributes iif they are set - fix l3num setting in expect/build.c
