FD table now holds both VFS1 and VFS2 types and uses the correct
one based on what's set.
Parts of this CL are just initial changes (e.g. sys_read.go,
runsc/main.go) to serve as a template for the remaining changes.

Special files can have additional requirements for granularity.
For example, read from eventfd returns EINVAL if a size is less 8 bytes.

This isn't in the libc wrapper, but it is in the syscall itself.
Discovered by @xiaobo55x in #1625.

And Type* over Type *. This is basically a whitespace only change.
gVisor code already prefers left-alignment of pointers and references, but
clang-format formats for consistency with the majority of a file, and some
files leaned the wrong way. This is a one-time pass to make us completely
conforming.
Autogenerated with:
$ find . \( -name "*.cc" -or -name "*.c" -or -name "*.h" \) \
| xargs clang-format -i -style="{BasedOnStyle: Google, \
DerivePointerAlignment: false, PointerAlignment: Left}"

In general, we've learned that logging must be avoided at all
costs in the hot path. It's unlikely that the optimizations
here were significant in any case, since buffer would certainly
escape.
This also adds a test to ensure that the caller identification
works as expected, and so that logging can be benchmarked.

Because the abi will depend on the core types for marshalling (usermem,
context, safemem, safecopy), these need to be flattened from the sentry
directory. These packages contain no sentry-specific details.

gonet.Conn can be created with both gonet.NewConn and gonet.Dial.
gonet.PacketConn was created only by gonet.DialUDP. This prevented
us from being able to use PacketConn in udp.NewForwarder() context.
This simple constructor - NewPacketConn, allows user to create
correct structure from that context.

Checksum computation is one of the most expensive bits of
packet processing. Manual unrolling of the loop provides
significant improvement in checksum speed.

Note that in VFS2, filesystem device numbers are per-vfs.FilesystemImpl rather
than global, avoiding the need for a "registry" type to handle save/restore.
(This is more consistent with Linux anyway: compare e.g.
mm/shmem.c:shmem_mount() => fs/super.c:mount_nodev() => (indirectly)
set_anon_super().)

Increase the timeout to 1s when waiting for async NDP events to help
reduce flakiness. This will not significantly increase test times as the
async events continue to receive an event on a channel. The increased
timeout allows more time for an event to be sent on the channel as the
previous timeout of 100ms caused some flakes.
Test: Existing tests pass

Go 1.14+ sends SIGURG to Ms to attempt asynchronous preemption of a G. Since it
can't guarantee that a SIGURG is only related to preemption, it continues to
forward them to signal.Notify (see runtime.sighandler).
We should ignore these signals, as applications shouldn't receive them. Note
that this means that truly external SIGURG can no longer be sent to the
application (as with SIGCHLD).

This pattern (delete from map when dropping) is also used in epoll.RemoveEntry,
and seems like generally a good idea.

The kernel may return EINTR from:
kvm_create_vm
kvm_init_mmu_notifier
mmu_notifier_register
do_mmu_notifier_register
mm_take_all_locks
Go 1.14's preemptive scheduling signals make hitting this much more likely.

Otherwise, this will be built when building a specific
release tag (typically in the past), causing the master
binary to be overwritten with something older.
We can generally assume that tags will be applied after
the commit has been integrated, and therefore that any
builds pointing to tags will use only the tags.
Another way to fix this would be to introduce something
akin to the KOKORO_BUILD_NIGHTLY environment variable,
but it doesn't seem strictly necessary.

- Wrap NIC's fields that should only be accessed while holding the mutex in
an anonymous struct with the embedded mutex.
- Make sure NIC's spoofing and promiscuous mode flags are only read while
holding the NIC's mutex.
- Use the correct endpoint when sending DAD messages.
- Do not hold the NIC's lock when sending DAD messages.
This change does not introduce any behaviour changes.
Tests: Existing tests continue to pass.

The iptables binary is looking for libxt_.so when it should be looking
for libxt_udp.so, so it's having an issue reading the data in
xt_match_entry. I think it may be an alignment issue.
Trying to fix this is leading to me fighting with the metadata struct,
so I'm gonna go kill that.
