Rather than re-downloading and installing Go for each pipeline run, we should
just do it at boot.

- Creates new metric "/tcp/segments_acked_with_dsack" to count the number of
segments acked with DSACK.
- Added check to verify the metric is getting incremented when a DSACK is sent
in the unit tests.

#6322 tried to update Go to 1.16, but existing nodes fail to upgrade due to the
presence of old Go [1]. Specifically when trying to add Go to `/usr/bin`:
```
ln: failed to create symbolic link '/usr/bin/go': File exists
```
Also:
- Removing `golang-go` also removes apt installs of `gcc` and `pkg-config`, so
those are installed explicitly.
- Add `-c` to wget, which will prevent re-downloading Go for each run.
- Disable GO111MODULE when building cri-tools and containerd, since we're using
pre-module versions of each.

The gofer session is killed when a gofer backed volume is unmounted. The
gofer monitor catches the disconnect and kills the container. This changes
the gofer monitor to only care about the rootfs connections, which cannot
be unmounted.

fs.renameMu is released and reacquired in `dentry.destroyLocked()` allowing
a dentry to be in `fs.syncableDentries` with a negative reference count.

We're currently on 1.13, which can cause build issues with code targeting later

TCP is fully supported. As with SO_RCVBUF, other transport protocols perform
no-ops per DefaultSocketOptionsHandler.OnSetReceiveBufferSize.

Remove the hack in gVisor vfs that allows verity to bypass the O_PATH
check, since ioctl is not allowed on fds opened with O_PATH in linux.
Verity still opens the lowerFD with O_PATH to open it as a symlink, but
the API no longer expects O_PATH to open a fd to be verity enabled.
Now only O_FOLLOW should be specified when opening and enabling verity
features.

It was confusing to find functions relating to root and non-root
containers. Replace "non-root" and "subcontainer" and make naming
consistent in Sandbox and controller.

Previously, two calls to set the send or receive buffer size could have raced
and left state wherein:
- The actual size depended on one call
- The value returned by getsockopt() depended on the other

Before this change, transmission of the first router solicitation races
with the adding of an IPv6 link-local address. This change creates the
NIC in the disabled state and is only enabled after the address is added
(if required) to avoid this race.

- Keeps Linux-specific behavior out of //pkg/tcpip
- Makes it clearer that clamping is done only for setsockopt calls from users
- Removes code duplication

Kernfs provides an internal mechanism to defer calls to `DecRef()` because
on the last reference `Filesystem.mu` must be held and most places that
need to call `DecRef()` are inside the lock. The same can be true for
filesystems that extend kernfs. procfs needs to look up files and `DecRef()`
them inside the `kernfs.Filesystem.mu`. If the files happen to be procfs
files, it can deadlock trying to decrement if it's the last reference.
This change extends the mechanism to external callers to defer DecRefs
to `vfs.FileDescription` and `vfs.VirtualDentries`.

Instead, roll the output scraping into the main runner. Pass a perf flag to
the runner in order to control leak checking, apply tags via the macro and
appropriately disable logging. This may be removed in the future.

Set stdio ownership based on the container's user to ensure the
user can open/read/write to/from stdios.
1. stdios in the host are changed to have the owner be the same
uid/gid of the process running the sandbox. This ensures that the
sandbox has full control over it.
2. stdios owner owner inside the sandbox is changed to match the
container's user to give access inside the container and make it
behave the same as runc.

Remove "partial write" handling as io.Writer.Write is not permitted to
return a nil error on partial writes, and this code was already
panicking on non-nil errors.

Go 1.17 adds a new register-based calling convention. While transparent for
most applications, the KVM platform needs special work in a few cases.
First of all, we need the actual address of some assembly functions, rather
than the address of a wrapper. See http://gvisor.dev/pr/5832 for complete
discussion of this.
More relevant to this CL is that ABI0-to-ABIInternal wrappers (i.e., calls from
assembly to Go) access the G via FS_BASE. The KVM quite fast-and-loose about
the Go environment, often calling into (nosplit) Go functions with
uninitialized FS_BASE.
That will no longer work in Go 1.17, so this CL changes the platform to
consistently restore FS_BASE before calling into Go code.
This CL does not affect arm64 code. Go 1.17 does not support the register-based
calling convention for arm64 (it will come in 1.18), but arm64 also does not
use a non-standard register like FS_BASE for TLS, so it may not require any
changes.
