- 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.

Commit 25b5ec7 moved link address resolution out of the transport layer;
special handling of link address resolution is no longer necessary in tcp.

Note, this includes static entries to match linux's behaviour.

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

Whether the variable was found is already returned by syscall.Getenv.
os.Getenv drops this value while os.Lookupenv passes it along.

Rather than dumping metrics on a single line, nearly unrelated textproto, print
them in alphabetical order, each on their own line.

If the release directory is a parent directory (for reasons), then this causes
a few problems (to say the least).

Files removed from the working tree were not being properly removed from
the branch, leading to symbol conflicts while building. This requires the
change to 'git add --all' in the tools/go_branch.sh script.
But why was this not caught by CI? The "git clean -f" command by default
only cleans files in the current working directory. In order to clean the
whole tree recursively, we need to specify a pathspec, which is ".".
In addition to these fixes, re-add the "go tests" command to help prevent
this from happening again, since merges on the Go branch will happen in
GitHub actions for simplicity. The Go test is retained in BuildKite.

When a control packet is delivered, it is delivered to a transport
endpoint with a matching stack.TransportEndpointID so there is no
need to pass the ID to the endpoint as it already knows its ID.

gvisor-containerd-shim is not compatible with containerd 1.1 or earlier.
Starting from containerd 1.2, shim v2 is the preferred interface.

This can race and cause issues. Instead, a manual shutdown can be done
via 'bazel-shutdown' if required for specific cases. The ARM64 builds
are now done using cross-compilation, so this hack is not necessary.

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.
