This change changes `buffer.data` into a `[]byte`, from `[bufferSize]byte`.
In exchange, each `buffer` is now grouped together to reduce the number of
allocation. Plus, `View` now holds an embeded list of `buffer` (via `pool`) to
support the happy path which the number of buffer is small. Expect no extra
allocation for the happy path.
It is to enable the use case for PacketBuffer, which
* each `View` is small (way less than `defaultBufferSize`), and
* needs to dynamically transfer ownership of `[]byte` to `View`.
(to allow gradual migration)

The new testutil.MockLinkEndpoint implementation is not composed by
channel.Channel anymore because none of its features were used.

When printing flags, FlagSet.PrintDefaults compares the Zero
value to the flag default value. The Zero refs.LeakMode value
was panicking in String() because it didn't expect the default
to be used

https://go.googlesource.com/go/+/0941fc3 switches the Go runtime (on amd64)
from using arch_prctl(ARCH_SET_FS) to CLONE_SETTLS to set the TLS.

Neither CLONE_PARENT_SETTID nor CLONE_CHILD_SETTID are used, so these arguments
will always be NULL.

Originally, we avoided partial writes in case it caused us to write a partial
packet to a socket-backed specialFileFD. However, this check causes splicing
from a pipe to specialFileFD to fail if we hit EOF on the pipe.

"DefaultValueEqZero" is only valid if the test is in a
sandbox. Our CI VMs often have "/proc/sys/net/ipv4/ip_forward" set
to 1.

`recv` calls with MSG_DONTWAIT can fail with EAGAIN randomly
in tests. Fix this by calling `select` on sockets with a timeout
prior to attempting a `recv`.

Unfortunately, I think TSC misalignment means that we can't really expect any
consistent correspondence between a TSC-based VDSO and the sentry's view of
time on the KVM platform.

This is more consistent with Linux (see comment on MM.NewSharedAnonMappable()).
We don't do the same thing on VFS1 for reasons documented by the updated
comment.

TCP needs to enqueue any send requests arriving when the connection is in
SYN_SENT state. The data should be sent out soon after completion of the
connection handshake.

Linux defines this struct as:
struct sched_param {
int priority;

Go does not call arch_prctl(ARCH_GET_FS), nor am I sure it ever did. Drop the

SO_LINGER is a socket level option and should be stored on all endpoints even
though it is used to linger only for TCP endpoints.

Docker does not have IPv6 port forwarding as tracked by the following issue:
https://github.com/moby/moby/issues/11518
So when running bazel itself inside a docker container, we can not use the host
port bindings to communicate with sockets inside the container. This was causing
integration tests and image tests to fail when run through our Makefile targets.

This constant is used to represent int32 stored in file xattrs. The
integers are stored as strings there, so the real size should be the
string size (number of digits) instead of an int size (4 bytes).

This is required to make tcpdump work. tcpdump falls back to not using things
like PACKET_RX_RING if setsockopt returns ENOPROTOOPT. This used to be the case
before https://github.com/google/gvisor/commit/6f8fb7e0db2790ff1f5ba835780c03fe245e437f.
Fixes #3981
