- 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
