packetEPs may get into a state that `len < cap`, casuing append() modifying the

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.

We should not assert that all resources are dropped after saving.

SO_OOBINLINE option is set/get as boolean value, which is the same as linux.
As we currently do not support disabling this option, we always return it as
true.

- Deep-copy pkt.Data and hold it instead of shallow-copy (vv.Clone).
This allows the pkt's backing array, which includes the header portion,
to be freed.
- Remove fragHeap. The fragments are now held in holes struct instead.
- Stop reserving the initial capacity of holes slice.

- Skip the bazel clean command on the last run of the benchmark.
- Use --test.benchtime=1ns to force running the benchmark once

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.

We do not rely on error for getsockopt options(which have boolean values)
anymore. This will cause issue in sendmsg where we used to return error
for IPV6_V6Only option. Fix the panic by returning error (for sockets other
than TCP and UDP) if the address does not match the type(AF_INET/AF_INET6) of
the socket.

These are not passing arguments properly. This breaks the current
pre-command for BuildKite.

For "hey", requests >= concurrency. b.N can be set by the
--test.benchtime={b.N}x. The previous setting of b.N * c
can be surprisingly slow for larger c.
Set the requests to max(b.N, c) and log to the user if it is c.

tcpip.ControlMessages can not contain Linux specific structures which makes it
painful to convert back and forth from Linux to tcpip back to Linux when passing
around control messages in hostinet and raw sockets.
Now we convert to the Linux version of the control message as soon as we are
out of tcpip.

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
