Added SI_CALL_STATS and ENABLE_SYSCALL_STATS for system call statistics.

Added BUSC_PCI_DEV_NAME_S and BUSC_PCI_SLOT_NAME_S to support safecopies in PCI.
Added DL_WRITEV_S, DL_READV_S, DL_GETSTAT_S, DL_GRANT, and iovec_s_t to support
safecopies in ethernet drviers. Renamed DL_INIT to DL_CONF, and DL_INIT_REPLY
to DL_CONF_REPLY.
Added SYS_READBIOS and sys_readbios to read from BIOS data areas.
Added GET_KMESS_S for safecopy support in LOG.
Added sys_safe_insb and sys_safe_outsb.
