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

Refactor the existing socket interface to share methods between VFS1 and VFS2.
The method signatures do not contain anything filesystem-related, so they don't
need to be re-defined for VFS2.
Updates #1476, #1478, #1484, #1485.

Previously, the import statement collision detection mechanism aborted
go-marshal whenever it detected two imports in any package that has
the same local name. Consider this trivial package, defined by the the
following two source files:
file1.go:
package example
import (
path/a/to/foo
)
...
file2.go:
package example
import (
another/package/with/final/component/foo
)
...
Go-marshal previously couldn't handle generating code for the the
above package, even if none of the types marked for marshalling used
either of the imported foo packages. This turns out to be too
restrictive as we run into this a lot in practice. Examples include
"encoding/binary" vs "gvisor/pkg/binary/binary", and "sync" vs
"gvisor/pkg/sync/sync".
This change allows go-marshal to proceed with marshalling, and only
abort if the code generated by go-marshal references any such
ambiguous import names.

A socket mount where anonymous sockets will reside is added to the
VirtualFilesystem. Socketfs is built on top of kernfs.

When copyUp fails, we attempt to clean up the upper filesystem by removing any
files that have already been copied-up. If the cleanup fails, we panic because
the "overlay filesystem is in an inconsistent state".
This CL adds the original copy-up error to the panic information, to hopefully
make it easier to track down how the overlay filesystem got into the
inconsistent state.

Some extra fields were added to the Mount type to expose necessary data to the
proc filesystem.
