Running the test 1000x almost always produces 1+ test failures where
the sample count is slightly more than 60.

Tested:
Sample output for printing 3 different Layer structs:
&testbench.Ether{SrcAddr:02:42:c4:77:5d:14 DstAddr:02:42:c4:77:5d:0a}
&testbench.IPv4{SrcAddr:196.119.93.20 DstAddr:224.0.0.1}
&testbench.UDP{SrcPort:0xc00033b260 DstPort:0xc00033b280}
Sample output for printing a Layers struct (word-wrapped):
[&testbench.Ether{SrcAddr:02:42:c4:77:5d:14 DstAddr:02:42:c4:77:5d:0a}
&testbench.IPv4{SrcAddr:196.119.93.20 DstAddr:224.0.0.1}

Software GSO implementation currently has a complicated code path with
implicit assumptions that all packets to WritePackets carry same Data
and it does this to avoid allocations on the path etc. But this makes it
hard to reuse the WritePackets API.
This change breaks all such assumptions by introducing a new Vectorised
View API ReadToVV which can be used to cleanly split a VV into multiple
independent VVs. Further this change also makes packet buffers linkable
to form an intrusive list. This allows us to get rid of the array of
packet buffers that are passed in the WritePackets API call and replace
it with a list of packet buffers.
While this code does introduce some more allocations in the benchmarks
it doesn't cause any degradation.

This change involves several steps:
- Refactor the VFS1 unix socket implementation to share methods between VFS1
and VFS2 where possible. Re-implement the rest.
- Override the default PRead, Read, PWrite, Write, Ioctl, Release methods in
FileDescriptionDefaultImpl.
- Add functions to create and initialize a new Dentry/Inode and FileDescription
for a Unix socket file.

NAME_MAX should be enforced per filesystem implementation
because other file systems may not have the same restriction.
Gofer filesystem now keeps a reference to the kernel clock to
avoid lookup in the Context on file access to update atime.
Update access, modification, and status change times in tmpfs.
Updates #1197, #1198.

As per RFC 6980 section 5, nodes MUST silently ignore NDP messages if
the packet carrying them include an IPv6 Fragmentation Header.

This is mostly required for PipeTest_OffsetCalls.
The options are DenyPRead/PWrite rather than AllowPRead/PWrite since, in Linux
terms, fs/open.c:do_dentry_open sets FMODE_PREAD|FMODE_PWRITE unconditionally
(although it allows filesystem implementations of open to unset these flags),
so they're set for most FDs; it's usually FDs created outside of open(2) that
don't get them, e.g.:
- Syscall-created pipes (fs/pipe.c:create_pipe_files =>
fs/file_table.c:alloc_file_pseudo)
- Epoll instances (fs/eventpoll.c:do_epoll_create =>
fs/anon_inodes.c:anon_inode_getfile => alloc_file_pseudo)
- Sockets (net/socket.c:sock_alloc_file => alloc_file_pseudo)
This CL adds the flags to epoll instances; a subsequent CL reworks the VFS2
implementation of pipe FDs to be filesystem-independent and adds the flags
there, and sockets aren't implemented yet.

The test is flaky in cooperative S/R mode because TCP timers are not restored
across a S/R. This can cause the TCPLinger2 timer to not fire. This change
disables S/R before setting the TCP_LINGER2 timeout.

"gcloud" may be installed as a snap, under "/snap/bin". Make
sure this is in our PATH so that we can use gcloud.

Previously, go-marshal only allowed literals for array
lengths. However, it's very common for ABI structs to have a fix-sized
array whose length is defined by a constant; for example PATH_MAX.
Having to convert all such arrays to have literal lengths is too
awkward.

Timeouts were increased to deflake pkg/tcpip/stack:stack_x_test tests
that depend on timers. Some timeouts used previously were intended for
tests that do not depend on timers, so this change updates those
timeouts to give more time for a timer-based event to occur. This
change also de-parallelizes non-subtests to reduce the number of active
timers.
Test: bazel test //pkg/tcpip/stack:stack_x_test --runs_per_test=500
