...to remove the need for the transport layer to deduce the type of
error it received.
Rename HandleControlPacket to HandleError as HandleControlPacket only
handles errors.
tcpip.SockError now holds a tcpip.SockErrorCause interface that
different errors can implement.

gvisor-containerd-shim is not compatible with containerd 1.1 or earlier.
Starting from containerd 1.2, shim v2 is the preferred interface.

The default pipe size already matched linux, and is unchanged.
Furthermore `atomicIOBytes` is made a proper constant (as it is in Linux). We
were plumbing usermem.PageSize everywhere, so this is no functional change.

This splits the nogo rules into a separate configuration yaml file, and
allows for multiple files to be provided.
Because attrs cannot be passed down to aspects, this required that all
findings are propagated up the aspect Provider. This doesn't mean that
any extra work must be done, just that this information must be carried
through the graph, and some additional starlark complexity is required.
