Right now, we send each tcp packet separately, we call one system
call per-packet. This patch allows to generate multiple tcp packets
and send them by sendmmsg.
The arguable part of this CL is a way how to handle multiple headers.
This CL adds the next field to the Prepandable buffer.

Like (AF_INET, SOCK_RAW) sockets, AF_PACKET sockets require CAP_NET_RAW. With
runsc, you'll need to pass `--net-raw=true` to enable them.
Binding isn't supported yet.

Linux kernel before 4.19 doesn't implement a feature that updates
open FD after a file is open for write (and is copied to the upper
layer). Already open FD will continue to read the old file content
until they are reopened. This is especially problematic for gVisor
because it caches open files.
Flag was added to force readonly files to be reopenned when the
same file is open for write. This is only needed if using kernels
prior to 4.19.
Closes #1006
It's difficult to really test this because we never run on tests
on older kernels. I'm adding a test in GKE which uses kernels
with the overlayfs problem for 1.14 and lower.

Options that do not change mount behavior inside the Sentry are
irrelevant and should not be used when looking for possible
incompatibilities between master and slave mounts.

We already do this for `runsc run`, but need to do the same for `runsc exec`.

Filter installation has been streamlined and functions renamed.
Documentation has been fixed to be standards compliant, and missing
documentation added. gofmt has also been applied to modified files.

This commit allows the use of the `--fsgofer-host-uds-allowed` flag to
enable mounting sockets and add the appropriate seccomp filters.

- Sandbox logs are generated when running tests
- Kokoro uploads the sandbox logs
- Supports multiple parallel runs
- Revive script to install locally built runsc with docker

Some processes are reparented to the root container depending
on the kill order and the root container would not reap in time.
So some zombie processes were still present when the test checked.
Fix it by running the second container inside a PID namespace.

This used to be the case, but regressed after a recent change.
Also made a few fixes around it and clean up the code a bit.
Closes #720

This is the first step in replacing some of the redundant types with the
standard library equivalents.

Endpoint protocol goroutines were previously started as part of
loading the endpoint. This is potentially too soon, as resources used
by these goroutine may not have been loaded. Protocol goroutines may
perform meaningful work as soon as they're started (ex: incoming
connect) which can cause them to indirectly access resources that
haven't been loaded yet.
This CL defers resuming all protocol goroutines until the end of
restore.

Each gofer now has a goroutine that polls on the FDs used
to communicate with the sandbox. The respective gofer is
destroyed if any of the FDs is closed.

We can get the mount namespace from the CreateProcessArgs in all cases where we
need it. This also gets rid of kernel.Destroy method, since the only thing it
was doing was DecRefing the mounts.
Removing the need to call kernel.SetRootMountNamespace also allowed for some
more simplifications in the container fs setup code.
