Such a stat accounts for all connections that are currently
established and not yet transitioned to close state.
Also fix bug in double increment of CurrentEstablished stat.

Bug 68320120 was revived because TODOs referenced the IP_RECVTOS bug instead
of the IPV6_RECVTCLASS bug.

Note that these simply will use the same logic as getxattr and setxattr, which
is not yet implemented for most filesystems.

Java 11 parses /proc/self/mountinfo for cgroup information. Java 11.0.4 uses
the mount path to determine what cgroups existed, but Java 11.0.5 reads the
cgroup names from the superblock options.
This CL adds the cgroup name to the superblock options if the filesystem type
is "cgroup". Since gVisor doesn't actually support cgroups yet, we just infer
the cgroup name from the path.

CERT Advisory CA-96.21 III. Solution advises that devices drop packets which
could not have correctly arrived on the wire, such as receiving a packet where
the source IP address is owned by the device that sent it.

x86 and arm64 use a different stat struct in Linux
kernel, so the stat() syscall implementation has
to handle the file stat data separately.

There is a lot of code duplication for VFSv2 and this
serves as remind to keep the copies in sync.

These can remain disabled until we actually support extended attributes.
The following modifications were also made:
1. Disable save/restore on tests that change file permissions. Restore will not
work properly for these tests, since it will try to open the file with
read-write after it has been read- or write-only.
2. Change user.abc to user.test.

There was a very bare get/setxattr in the InodeOperations interface. Add
context.Context to both, size to getxattr, and flags to setxattr.
Note that extended attributes are passed around as strings in this
implementation, so size is automatically encoded into the value. Size is
added in getxattr so that implementations can return ERANGE if a value is larger
than can fit in the user-allocated buffer. This prevents us from unnecessarily
passing around an arbitrarily large xattr when the user buffer is actually too
small.
Don't use the existing xattrwalk and xattrcreate messages and define our
own, mainly for the sake of simplicity.
Extended attributes will be implemented in future commits.

sys_clone has many flavors in Linux, and amd64 chose
a different one from x86(different arguments order).
Ref kernel/fork.c for more info.

If a previously added IPv6 address (statically or via SLAAC) was removed, it
would be left in an expired state waiting to be cleaned up if any references to
it were still held. During this time, the same address could be regenerated via
SLAAC, which should be allowed. This change supports this scenario.
When upgrading an endpoint from temporary or permanentExpired to permanent,
respect the new configuration type (static or SLAAC) and deprecated status,
along with the new PrimaryEndpointBehavior (which was already supported).
Test: stack.TestAutoGenAddrAfterRemoval

This change adds support to send NDP Router Solicitation messages when a NIC
becomes enabled as a host, as per RFC 4861 section 6.3.7.
Note, Router Solicitations will only be sent when the stack has forwarding
disabled.
Tests: Unittests to make sure that the initial Router Solicitations are sent
as configured. The tests also validate the sent Router Solicitations' fields.

The change to introduce worker goroutines can cause the endpoint
to transition to StateError and we should terminate the loop rather
than let the endpoint transition to a CLOSED state as we do
in case the endpoint enters TIME-WAIT/CLOSED. Moving to a closed
state would cause the actual error to not be propagated to
any read() calls etc.

All inbound segments for connections in ESTABLISHED state are delivered to the
endpoint's queue but for every segment delivered we also queue the endpoint for
processing to a selected processor. This ensures that when there are a large
number of connections in ESTABLISHED state the inbound packets are all handled
by a small number of goroutines and significantly reduces the amount of work the
goscheduler has to perform.
We let connections in other states follow the current path where the
endpoint's goroutine directly handles the segments.

Do Source Address Selection when choosing an IPv6 source address as per RFC 6724
section 5 rules 1-3:
1) Prefer same address
2) Prefer appropriate scope
3) Avoid deprecated addresses.
A later change will update Source Address Selection to follow rules 4-8.
Tests:
Rule 1 & 2: stack.TestIPv6SourceAddressSelectionScopeAndSameAddress,
Rule 3: stack.TestAutoGenAddrTimerDeprecation,
stack.TestAutoGenAddrDeprecateFromPI
