Analyzer test was missing imports.
IPFIX templates with 16 bytes fields were processed extra, since struct
does not natively support conversion to int. The new implementation
still handles it extra, but uses struct's "s" unpack format descriptor
now.
The previously introduced tests/lib.py contained the NetFlow v9 packets
and then the IPFIX packets, those were split and put into their
respective test files again. The lib now contains shared objects only.
For IPFIX tests were added. Two new packets were added, one with
templates and one without (again, real exports from softflowd).
Different cases are checked: no template, template and later template.
Fields of flows are also checked, especially IPv6 addresses.
Note: exports made with softflowd were created by softflowd 1.0.0,
compiled from https://github.com/irino/softflowd
The tests are now located in tests/. They are also split into multiple
files, beginning with test_netflow and test_analyzer. The tests for
IPFIX will be added to test_ipfix.
