There are surprisingly few syscall tests that run with hostinet. For example
running the following command only returns two results:
`bazel query test/syscalls:all | grep hostnet`
I think as a result, as our control messages evolved, hostinet was left
behind. Update it to support all control messages netstack supports.
This change also updates sentry's control message parsing logic to make it up to
date with all the control messages we support.

This command takes instruction pointers from stdin and converts them into their
corresponding file names and line/column numbers in the runsc source code. The
inputs are not interpreted as actual addresses, but as synthetic values that are
exposed through /sys/kernel/debug/kcov. One can extract coverage information
from kcov and translate those values into locations in the source code by
running symbolize on the same runsc binary.
This will allow us to generate syzkaller coverage reports.

fdbased endpoint was enabling fragment reassembly on the host AF_PACKET socket
to ensure that fragments are delivered inorder to the right dispatcher. But this
prevents fragments from being delivered to gvisor at all and makes testing of
gvisor's fragment reassembly code impossible.
The potential impact from this is minimal since IP Fragmentation is not really
that prevelant and in cases where we do get fragments we may deliver the
fragment out of order to the TCP layer as multiple network dispatchers may
process the fragments and deliver a reassembled fragment after the next packet
has been delivered to the TCP endpoint. While not desirable I believe the impact
from this is minimal due to low prevalence of fragmentation.
Also removed PktType and Hatype fields when binding the socket as these are not
used when binding. Its just confusing to have them specified.
See: https://man7.org/linux/man-pages/man7/packet.7.html
"Fields used for binding are
sll_family (should be AF_PACKET), sll_protocol, and sll_ifindex."
Fixes #5055

A few images were broken with respect to aarch64. We should now
be able to run push-all-images with ARCH=aarch64 as part of the
regular continuous integration builds, and add aarch64 smoke tests
(via user emulation for now) to the regular test suite (future).

c.Usage() only returns a string; f.Usage() will print the usage message.

We have seen a case when a memory cgroup exists but a perf_event one doesn't.

Container is not thread-safe, locking must be done in the caller.
The test was calling Container.Wait() from multiple threads with
no synchronization.
Also removed Container.WaitPID from test because the process might
have already existed when wait is called.

- Make AddressableEndpoint optional for NetworkEndpoint.
Not all NetworkEndpoints need to support addressing (e.g. ARP), so
AddressableEndpoint should only be implemented for protocols that
support addressing such as IPv4 and IPv6.
With this change, tcpip.ErrNotSupported will be returned by the stack
when attempting to modify addresses on a network endpoint that does
not support addressing.
Now that packets are fully handled at the network layer, and (with this
change) addresses are optional for network endpoints, we no longer need
the workaround for ARP where a fake ARP address was added to each NIC
that performs ARP so that packets would be delivered to the ARP layer.

When OOM score adjustment needs to be set, all the containers need to be
loaded to find all containers that belong to the sandbox. However, each
load signals the container to ensure it is still alive. OOM score
adjustment is set during creation and deletion of every container, generating
a flood of signals to all containers. The fix removes the signal check
when it's not needed.
There is also a race fetching OOM score adjustment value from the parent when
the sandbox exits at the same time (the time it took to signal containers above
made this window quite large). The fix is to store the original value
in the sandbox state file and use it when the value needs to be restored.
Also add more logging and made the existing ones more consistent to help with
debugging.

This is useful to optionally set /dev ro,noexec.
Treat /dev and /dev/pts the same as /proc and /sys.
Make sure the Type is right though. Many config.json snippets
on the Internet suggest /dev is tmpfs, not devtmpfs.
