Message:

reconf: introducing the CC_TEST FSM in the vci_mem_cache

• The VciMemCache? and VciCcVcacheWrapper? components use the reconf version of dhccp_dspin_param.

• This FSM receives commands from the CC_RECEIVE FSM and acknowledge them through the CLEANUP and CC_SEND FSM.

• This commit is incomplete. The communication between the CC_TEST FSM and the CLEANUP and CC_SEND FSMs is not completely implemented.
