protocol: reject illegal lco options
At the moment osmo-mgw will accept multiple lco options. (e.g.
p:10, a:PCMU, p:10) If LCO appear multiple times, than the first
appearance of will be parsed and used, all following appearances
will be ignored. However, having multiple appearances of LCO is
illegal and affected requests should be rejected. Also osmo-mgw
should reject illegal formatted LCO strings
- make sure that multiple appearances of LCOs will be rejected
- make sure that illegal formated LCOs are rejected
- add testcases with garbeled LCO and valid LCO examples
