SRVID ranges: Change the ranges for SRVIDs to allow 8 bit prefixes

Update the ranges used for SRVID allocation to allow 8 bit prefixes and thus
56 user-defined bits.
Define the defacto-use of the 0x00 prefix as a SRVID used to register a process id
Upgrade SAMBA/iSCSI/NFS/TEST from a 32 bit prefix each ot a 8 bit prefix each
for private use.
