------------- Moves ecm_generator to media_cas_packager_sdk/internal. ------------- Add a simple TCP server listening on a port. My intention is to use this server to support the Simulcrypt APIs (TODO). Also add a simple TCP client binary for testing the server and also demo how to call the Simulcrypt APIs (TODO). ------------- If only a single key is in the ECM, it is the EVEN key. To make the code matches this understanding, change a parameter from 'false' to 'true'. But this change has NO impact on the produced ECM, regardless this parameter is 'false' or 'true' (i.e., whether using push_front or push_back), only a single key is in the ECM. ------------- Add classes that process Simulcrypt ECMG messages 1) Stream_set-up 2) CW_provision ------------- Renames server and client binaries. ------------- Make ecmg call ecm_generator to generate ecm. The return of the ecm to Simulcrypt caller will be implemented in the next CL. For now, using the 'key' (control word) in CW_provision message also as the 'key_id'. ------------- Move common folder ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=217358698
