add testsuite infrastructure and osmux test
This patch adds the testsuite infrastructure and it populates it with one test for osmux. The osmux tests makes sure that: * We get the same number of RTP messages in the input and the output path. * The payload of the RTP message is reconstructed correctly. * The reconstructed timing is correct.
