codec/ecu: Introduce new generic Error Concealment Unit abstraction
We don't want to expose the details of a given ECU implementation to the user (e.g. osmo-bts), but have a generic abstraction layer where an ECU implementation can simply register a few call-back functions with the generic core. As the developer and copyright holder of the related code, I hereby state that any ECU implementation using 'struct osmo_ecu_ops' and registering with the 'osmo_ecu_register()' function shall not be considered as a derivative work under any applicable copyright law; the copyleft terms of GPLv2 shall hence not apply to any such ECU implementation. The intent of the above exception is to allow anyone to combine third party Error Concealment Unit implementations with libosmocore, including but not limited to such published by ETSI.
