Previously, SLAAC related state was stored on a per-address basis. This was
sufficient for the simple case of a single SLAAC address per prefix, but
future CLs will introduce temporary addresses which will result in multiple
SLAAC addresses for a prefix. This refactor allows storing multiple addresses
for a prefix in a single SLAAC prefix state.
No behaviour changes - existing tests continue to pass.

- Make oomScoreAdj a ThreadGroup field (Linux: signal_struct::oom_score_adj).
- Avoid deadlock caused by Task.OOMScoreAdj()/SetOOMScoreAdj() locking Task.mu
and TaskSet.mu in the wrong order (via Task.ExitState()).

When a NIC is removed, attempt to disable the NIC first to cleanup
dynamic state and stop ongoing periodic tasks (e.g. IPv6 router
solicitations, DAD) so that a removed NIC does not attempt to send
packets.
Tests:
- stack_test.TestRemoveUnknownNIC
- stack_test.TestRemoveNIC
- stack_test.TestDADStop
- stack_test.TestCleanupNDPState
- stack_test.TestRouteWithDownNIC
- stack_test.TestStopStartSolicitingRouters

- Don't allocate []*endpointsByNic in transportDemuxer.deliverPacket() unless
actually needed for UDP broadcast/multicast.
- Don't allocate []*endpointsByNic via transportDemuxer.findEndpointLocked()
=> transportDemuxer.findAllEndpointsLocked().
- Skip unnecessary map lookups in transportDemuxer.findEndpointLocked() =>
transportDemuxer.findAllEndpointsLocked() (now iterEndpointsLocked).
For most deliverable packets other than UDP broadcast/multicast packets, this
saves two slice allocations and three map lookups per packet.

Note that the raw faccessat system call does not actually take a flags argument;
according to faccessat(2), the glibc wrapper implements the flags by using
fstatat(2). Remove the flag argument that we try to extract from vfs1, which
would just be a garbage value.

2aa9514a06a5e34894e606d508ac2df53b082c74 skips SIGURG, but later code expects
the sigchans array contains consecutive signal numbers.

LinkEndpoints may expect/assume that the a tcpip.PacketBuffer's Header
has enough capacity for its own headers, as per documentation for
LinkEndpoint.MaxHeaderLength.

When the sandbox runs in attached more, e.g. runsc do, runsc run, the
sandbox lifetime is controlled by the parent process. This wasn't working
in all cases because PR_GET_PDEATHSIG doesn't propagate through execve
when the process changes uid/gid. So it was getting dropped when the
sandbox execve's to change to user nobody.

...instead of sorting at various times. Plug a memory leak by setting
removed elements to nil.

Atomically close the endpoint. Before this change, it was possible for
multiple callers to perform duplicate work.

This also adds substantial test cases.
The Read/Write interfaces are dropped as they are not necessary.

Endpoints which were being terminated in an ERROR state or were moved to CLOSED
by the worker goroutine do not run cleanupLocked() as that should already be run
by the worker termination. But when making that change we made the mistake of
not removing the endpoint from the danglingEndpoints which is normally done in
cleanupLocked().
As a result these endpoints are leaked since a reference is held to them in the
danglingEndpoints array forever till Stack is torn down.

Fixed flakes (tested via --runs_per_test=100) and added skips for
not-yet-implemented features. Once submitted, the iptables tests will be
ready to enable in kokoro.
