* This file contains function declaration and structures for rate control
* memtabs
*
* @author
* ittiam
*
* @remarks
* The rate control library is a global library across various codecs. It
* anticipates certain structures definitions. Those definitions are to be
* imported from global workspace. Instead of that, the structures needed for
* rc library are copied in to this file and exported to rc library. If the
* structures / enums / ... in the global workspace change, this file also needs
* to be modified accordingly.
