OML: Improve OML attribute handling

the OML attribute tables are hardcoded. To set variable parameters,
the hardcoded data structure (tlv) is patched on byte level during
runtime. This patch replaces this mechanism.

- Replace hardcoded OML attribute tables with dynamically
  generated TLV structures.

- Add unit tests to check if the OML attribute tables are
  generated correctly

- Put OML attribute table generator code in a separate file:
  bts_ipaccess_nanobts_omlattr.c
