DUT logs will include logs from the posix server and gVisor, which
provides a way to instrument the DUT during test failures.

Now it calls pkt.Data.ToView() when writing the packet. This may require
copying when the packet is large, which puts the worse case in an even worse
situation.
This sent out in a separate preparation change as it requires syscall filter
changes. This change will be followed by the change for the adoption of the new
PacketHeader API.

Packet sockets also seem to allow double binding and do not return an error on
linux. This was tested by running the syscall test in a linux namespace as root
and the current test DoubleBind fails@HEAD.
Passes after this change.

gVisor incorrectly returns the wrong ARP type for SIOGIFHWADDR. This breaks
tcpdump as it tries to interpret the packets incorrectly.
Similarly, SIOCETHTOOL is used by tcpdump to query interface properties which
fails with an EINVAL since we don't implement it. For now change it to return
EOPNOTSUPP to indicate that we don't support the query rather than return
EINVAL.
NOTE: ARPHRD types for link endpoints are distinct from NIC capabilities
and NIC flags. In Linux all 3 exist eg. ARPHRD types are stored in dev->type
field while NIC capabilities are more like the device features which can be
queried using SIOCETHTOOL but not modified and NIC Flags are fields that can
be modified from user space. eg. NIC status (UP/DOWN/MULTICAST/BROADCAST) etc.

`set -e` does not catch errors in bash command substituions like
`echo $(bad cmd)` so bazel thinks it succeeded and cached the result.

Much like the boot process, apply pdeathsig to the gofer for cases where
the sandbox lifecycle is attached to the parent (runsc run/do).
This isn't strictly necessary, as the gofer normally exits once the
sentry disappears, but this makes that extra reliable.
When we failed to create the new socket after adding the fd to
fdnotifier, we should remove the fd from fdnotifier, because we
are going to close the fd directly.

To implement stat(2) in FUSE, we have to embed credentials and pid in request
header. The information should be extracted from the context passed to VFS
layer. Therefore `Stat()` signature in `kernfs.Inode` interface should include
context as first argument. Some other fs implementations need to be modified as
well, such as devpts, host, pipefs, and proc.

Add a conditional to avoid running the issue reviver on forks. It will
always cause errors since bug references in the source code don't match
issue IDs in forked repos.

This rule isn't restored when the Kokoro VM is restarted, so it's not doing
anything. And the problem it was meant to solved is instead addressed by
https://github.com/google/gvisor/pull/3207.

For accessing metadata fields:
- If metadataMu is locked, we can access without atomics
- If metadataMu is unlocked, we should use atomics
For mutating metadata fields:
- Always lock metadataMu and use atomics.
There were some instances of inconsistencies which have been fixed.

Earlier we were docker exec-ing each test at a time. However invoking the test
framework has a fixed overhead which made it infeasible to make the runtime
tests run as presubmits. This change now executes tests in batches of 50 (can
be altered). This really speeds up testing process.
With this change, the following tests can be run in reasonable times:
- Go
- Nodejs
- Php
- Python

Split the kvm ut test cases to pass unit-tests on Arm64.
I will add the tls and full-context test cases for Arm64 later.
