If data is sent over a stream socket that will not fit all at once, it will
be sent over multiple packets. SCM Rights should only be sent with the first
packet (see net/unix/af_unix.c:unix_stream_sendmsg in Linux).

This CL moves {S,G}etsockopt of SO_SNDBUF from all endpoints to socketops. For
unix sockets, we do not support setting of this option.

IN_CLOSE should only be generated when a file description loses its last
reference; not when a file descriptor is closed.
See fs/file_table.c:__fput.
Updates #5348.

The ARP stat NetworkUnreachable was removed, and was replaced by
InterfaceHasNoLocalAddress. No stats are recorded when dealing with an
missing endpoint (ErrNotConnected) (because if there is no endpoint,
there is no valid per-endpoint stats).

We have support for the output interface name, but not for the input
interface name.
This change adds the support for the input interface name, and adds the
test cases for it.

On ARM64, when ptrace stops on a system call, it uses the x7 register to
indicate whether the stop has been signalled from syscall entry or syscall
exit. This means that we can't get a value of this register and we can't change
it. More details are in the comment for tracehook_report_syscall in
arch/arm64/kernel/ptrace.c.
This happens only if we stop on a system call, so let's queue a signal, resume
a stub thread and catch it on a signal handling.

The same intent can be specified via the io.Writer.

- Remove the pipe package's dependence on the buffer package, which becomes
unused as a result. The buffer package is currently intended to serve two use
cases, pipes and temporary buffers, and does neither optimally as a result;
this change facilitates retooling the buffer package to better serve the
latter.
- Pass callbacks taking safemem.BlockSeq to the internal pipe I/O methods,
which makes most callbacks trivial.
- Fix VFS1's splice() and tee() to immediately return if a pipe returns a
partial write.

Return EEXIST when overwritting a file as long as the caller has exec
permission on the parent directory, even if the caller doesn't have
write permission.
Also reordered the mount write check, which happens before permission
is checked.

Link address resolution is performed at the link layer (if required) so
we can defer it from the transport layer. When link resolution is
required, packets will be queued and sent once link resolution
completes. If link resolution fails, the transport layer will receive a
control message indicating that the stack failed to route the packet.
tcpip.Endpoint.Write no longer returns a channel now that writes do not
wait for link resolution at the transport layer.
tcpip.ErrNoLinkAddress is no longer used so it is removed.
Removed calls to stack.Route.ResolveWith from the transport layer so
that link resolution is performed when a route is created in response
to an incoming packet (e.g. to complete TCP handshakes or send a RST).
Tests:
- integration_test.TestForwarding
- integration_test.TestTCPLinkResolutionFailure
Fixes #4458

These are primarily simplification and lint mistakes. However, minor
fixes are also included and tests added where appropriate.

This requires several changes:
* Templates must preserve relevant tags.
* Pagetables templates are split into two targets, each preserving tags.
* The binary VDSO is similarly split into two targets, with some juggling.
* The top level tools/go_branch.sh now does a crossbuild of ARM64 as well,
and checks and merges the results of the two branches together.
