Message:

Updated of the vci trdid/rtrdid and pktid/rpktid fields for the direct network.
The pktid values are commented in the components'headers that use them.

• In the vci_vdspin_*_wrapper components
  • added the transmission of the pktid/rpktid field
• In the vci_cc_vcache_wrapper_v4
  • updated gen_moore() to transmit a valid pktid
  • updated transition(), RSP_FSM now checks the rpktid
• In the vci_mem_cache_v4
  • transition(), tests originally performed on trdid now use pktid
  • gen_moore() transmit rpktid
  • !!! THE L1_MULTI_CACHE MECHANISM IS NO LONGER COMPATIBLE !!!
• In vci_block_device_tsar_v4
  • updated gen_moore function to transmit a valid pktid

Also renamed the "SC" states in "CAS" states in the concerned FSMs on the vci_cc_vcache_wrapper_v4 and the vci_mem_cache_v4
