Change subject: ASCI: Add GCC/BCC (call control) to mobility management
......................................................................
ASCI: Add GCC/BCC (call control) to mobility management
GCC is the call control for voice group calls, BCC is the call control
for voice broadcast calls.
This patch includes the new message primitives between MM layer and the
GCC/BCC layers.
