Note that most kinds of sockets are not yet supported in VFS2
(only Unix sockets are partially supported at the moment), so
these syscalls will still generally fail. Enabling them allows
us to begin running socket tests for VFS2 as more features are
ported over.
Updates #1476, #1478, #1484, #1485.

The comments in the ticket indicate that this behavior
is fine and that the ticket should be closed, so we shouldn't
need pointers to the ticket.

As in VFS1, we only support the user.* namespace. Plumbing is added to tmpfs
and goferfs.
Note that because of the slightly different order of checks between VFS2 and
Linux, one of the xattr tests needs to be relaxed slightly.
Fixes#2363.

Continues the modifications in cl/272963663. This prevents non-syscall errors
from being propogated to kernel/task_syscall.go:ExtractErrno(), which causes a
sentry panic.

The dependency strace=>kernel grew over time. strace also depends on
task's FD table and FSContext. It could be fixed with some interfaces
the other way, but then we're trading an interface for another, and
kernel.Stracer is likely cleaner.
Closes#155

It was added in cl/201419897 to deflake
socket_ip_tcp_loopback_non_blocking_test_gvisor.
It seems we don't need this hack, because the origin issue isn't
reproducible without this hack.

Better validate NDP NS messages and their options before doing work in
response to them. Also make sure that NA messages sent in response to
an NS use the correct IPv6 and link-layer addresses so they are
routed properly and received by the right node.

When a command is called as if expression, its error
code can be get only in this if block.
For example, the next script prints 0:
if ( false ); then
true
fi
echo $?

Dereference any fields which are pointers before string formatting so that the
value pointed to ends up in the string representation.
Tested:
Added TestLayerStringFormat to

Determine system time from within the sentry rather than relying on the remote
filesystem to prevent inconsistencies.
Resolve related TODOs; the time discrepancies in question don't exist anymore.

FileDescription references are side-effectual; for example, holding a reference
on the write end of a pipe prevents reads from the read end from returning EOF.
This change is consistent with Linux, but not VFS1; while VFS1 also has this
bug, it's less visible there since VFS1 procfs disables caching.
