Return to cache.h CVS log

Up to [local] / src / usr.bin / systat

use a u_int64_t for the state id in pfsync_state. this makes it consistent
with every other thing that stores the state id (including other pfsync
messages).

includes improvements to the systat code to consider the creatorid as well
as the state id in its cache to avoid collisions between states created on
different hosts.

tested by me in production and on amd64 talking to sparc64.
