-------------
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
