Save sph->src_key and use it when calculating named worker index, since it will be overwritten for blocked events
Get rid of old/unused exec/push - locked/unlocked, use plain exec/push and lock flag from session.cflags
Added new exec() method which assigns sph->src_key from its parameter
Use round-robin sph->src_key assignment. Added \n back into srw_log class to workaround cocaine messages, which do not contain it.
