There was a check generating an internal warning if a new packet
analyzer mapping overwrote an existing one. However, replacing
an existing analyzer with a new one seems a legitimate use case (and
will be supported by Spicy soon). So removing that warning.
This is WIP: The test case would require a new pcap or the possibility
to overwrite analyzer mappings. The CustomEncapsulationSkip method and
the corresponding options need to be removed.
This is still WIP and includes the following changes:
* Dispatchers are now part of analyzers (moving dispatching logic from
the manager to the analyzers)
* All available analyzers are instantiated on start up
* Removal of configuration class
