...instead of calculating a fresh checksum to avoid re-calcalculating
a checksum on unchanged bytes.
Fixes #5340.

This change prepares for a later change which supports the NDP
Route Information option to discover more-specific routes, as
per RFC 4191.
The newly introduced off-link route state will be used to hold
both the state for default routers (which is a default (off-link)
route through the router, and more-specific routes (which are
routes through some router to some destination subnet more specific
than the IPv6 empty subnet).
Updates #6172.

A caller of CreateProcessGroup looks up a thread group without locks, so
the target process can exit before CreateProcessGroup will be called.

While #6204 addressed the stopped state for handling signals in the main
process, it did not update exec processes in the same way. This change
mirrors that adjustment for exec processes.

This change wraps containerd's errdefs.ToGRPC function with one that
understands Go 1.13-style error wrapping style, which is used
pervasively throughout the shim. With this change, errors that have been
marked with, e.g., `errdefs.ErrNotFound`, will be correctly propagated
back to the containerd server.

There are unnecessarily short timeouts in several places.
Note: a later change will switch tcp_test to fake clocks intead of the built-in
`time` package.

Add Equals method to compare syserror and unix.Errno errors to linuxerr errors.
This will facilitate removal of syserror definitions in a followup, and
finding needed conversions from unix.Errno to linuxerr.

tcpdump is largely supported. We've also chose not to implement writeable
AF_PACKET sockets, and there's a bug specifically for promiscuous mode (#3333).
Fixes #173.

Getting state of a stopped container would fail and could lead containerd
to not detecting that the container had actually stopped. Now stopped and
deleted containers return `stopped` state.
Also makes other messages more consistent when container is stopped. Some
where still sending messages to runsc and failing in different ways. Now
they go through `initState` state machine like the other messages.
There are a few changes to improve debugability with it as well.
Fixes #5861

It was possible for a SYN to arrive after the endpoint sent an ACK as part of
the transition to TIME-WAIT, but before returning from handleSegmentsLocked().
This caused the SYN to be dequeued and ACK'd despite the change in
EndpointState.
Deflakes TestTCPTimeWaitNewSyn.
Tested with:
blaze test --config=gotsan --runs_per_test 10000 \
//third_party/gvisor/pkg/tcpip/transport/tcp:tcp_x_test -j 2000 \
// --test_filter TestTCPTimeWaitNewSyn

epsByNIC.registerEndpoint can add a multiportEndpoint to its map of
nic->multiportEndpoint even if multiport.Endpoint.singleRegisterEndpoint
failed. Same for transportDemuxer.singleRegisterEndpoint which ends up adding an
entry to nic->epsByNIC even if epsByNIC.registerEndpoint fails.
These breaks an invariant which the code assumes that a
multiportEndpoint/endpointsByNIC always have at least one valid entry.

RFC 4191 supports the notion of a preference value for default routers
and more-specific routes, so update the OffLinkRouteUpdate event to
include this preference value so integrators may prioritize routes
based on a route's advertised preference value.
Note, more-specific route discovery is not supported yet, but will be in
a later change.
Updates #6172.

Change the p9 server to use *errors.Error defined in pkg linuxerr. Done
separate from the client so that we ensure different p9 server/client versions
