* auth:
fix osdGetRoles
oops
Add showauth executable
getgrouplist() on OSX has different sig.
auth fix mingw static
fix search PeerInfo
PeerInfo in pva/server.h and pva/sharedstate.h
make PeerInfo available during search phase
auth status void accidental success.
minor doc
always need to link with netapi32 now
authorize with local group lookup
Add osdGetRoles()
authorization framework
pvasr show PeerInfo
redo security (aka. access control)
remove asCheck

Apparently SIO_GET_INTERFACE_LIST sometimes gives
the global broadcast (255.255.255.255) for one of
the interfaces. In this case silently compute
the iface bcast address.
in favor of discoverInterfaces().
if we have to do NIC discovery ourselves, then at least
avoid mixing our results with the similar, but not identical
results of osiSockDiscoverBroadcastAddresses() from Base.
change interface to distingush between bcast and point2point.
add netmask to truly distinguish unicast from bcast.
fix some minor (I think) errors in the bsd socks impl (use of clobbered buffer).
cleanup win32 impl. bcast and p2p handling.
Calling code can't deal with "cache" miss,
which indicates either a protocol error (use of invalid ID),
or a logic error on our part (didn't save ID).
In either case, better to throw an exception than to crash.
with bcast interfaces, send searches to bcast address
and !WIN32 binds bcast address to receive searches.
with point to point, send searches to dest address.
can't bind dest address (not local).
quiets spurious error message:
> Error binding socket: Cannot assign requested address.
Encountered with a P2P link setup by openvpn.
This approach works OK, but makes it much harder to find files
that have mistakes in them since they can cause other functions
to get the wrong import/export setting.
