The presence of multiple packages in a single directory sometimes
confuses `go mod`, producing output like:

The current implementation has a bug where TCP listener does not ignore
RSTs from the peer. While handling RST+ACK from the peer, this bug can
complete handshakes that use syncookies. This results in half-open
connection delivered to the accept queue.
Fixes #6076

Executing `select {}` to wait forever triggers Go runtime deadlock
detection and kills the child, causing the number actual processes
be less than expected.

Adds support for the SO_BINDTODEVICE socket option in ICMP sockets with an
accompanying packetimpact test to exercise use of this socket option.
Adds a unit test to exercise the NIC selection logic introduced by this change.
The remaining unit tests for ICMP sockets need to be added in a subsequent CL.
See https://gvisor.dev/issues/5623 for the list of remaining unit tests.
Adds a "timeout" field to PacketimpactTestInfo, necessary due to the long
runtime of the newly added packetimpact test.

Testing only TestBindToDeviceDistribution decreased from 24s to 11s, and with
TSAN from 186s to 21s.
Note: using `t.Parallel()` actually slows the test down.

on Arm64 platform, we can use TLBI with 'IS' instead of IPI operation.
According to my understanding, the logic in invalidate() is much like
an IPI operation.
On Arm64, we can simply perform vmalle1is invalidation here, not
use IPI.

This change also includes miscellaneous improvements:
* UnknownProtocolRcvdPackets has been separated into two stats, to
specify at which layer the unknown protocol was found (L3 or L4)
* MalformedRcvdPacket is not aggregated across every endpoint anymore.
Doing it this way did not add useful information, and it was also error-prone
(example: ipv6 forgot to increment this aggregated stat, it only
incremented its own ipv6.MalformedPacketsReceived). It is now only incremented
the NIC.
* Removed TestStatsString test which was outdated and had no real
utility.

Previously, mount could discover a hierarchy being destroyed
concurrently, which resulted in mount attempting to take a ref on an
already destroyed cgroupfs.

Before this change, we would silently drop packets when link resolution
failed. This change brings us into line with RFC 792 (IPv4) and RFC 4443 (IPv6),
both of which specify that gateways should return an ICMP error to the sender
when link resolution fails.

Before fix, use of this flag causes an error.
It affects applications like OpenVPN which sets this flag for legacy reasons.
According to linux/if_tun.h "This flag has no real effect".

Fuchsia was unable to build when building netstack transitively depended on
golang.org/x/unix constants not defined in Fuchsia. The packages causing this
(safemem and usermem) are no longer in the allowlist.
Tested that this failed at cl/373651666, and passes now that the dependency has
been removed.

Add linuxerr package to replace syserror and syserr errors. This is done
to improve performance comparing/returning errors to on par with
syscall.Errno.
The below linuxerr_test (formerly syserror_test) shows linuxerr.Error
on par with unix.Error (syscall.Errno) as desired.
