[PATCH 1/3] decnet: Move to staging

[Ben Hutchings <ben@decadent.org.uk>]

Recent review has revealed several bugs in obscure protocol
implementations that can be exploited by local users for denial of
service or privilege escalation.

The decnet protocol (PF_DECnet) is unmaintained.  Since 2.6.12-rc2 the
only changes appear to be adjustments for net API changes and fixes
for bugs found by inspection.

This protocol generally should not be enabled by distributions, since
the cost of a security flaw affecting all installed systems presumably
outweighs the benefit to the few (if any) legitimate users.
