6bb6d4dd5a vendoring: Update gopacket to latest master 
We'd like to benefit from the memory reduction from:

  https://github.com/google/gopacket/pull/377

I just ran:

  $ gvt update github.com/google/gopacket

Fixes: https://github.com/weaveworks/scope/issues/2905

8cf79b2e4a bump tcptracer-bpf version and use it to fix race 
We defer starting the ebpf tracer until we've set the global var which
is referenced by the callback functions. Previously the var could be
unset when the callbacks are invoked, resulting in a segfault.

Fixes #2687.

a306867610 fast network membership check 
The rendering code checks whether endpoint IPs are part of
cluster-local networks. Due to the prevalence of endpoints - medium
sized reports can contain many thousands of endpoints - this is
performance critical. Alas the existing code performs the check via a
linear scan of a list of networks. That is slow when there are more
than a few, which will be the case in the context of k8s, since there
the probes register service IPs as local /32 networks.

Here we change representation of the set of networks to a prefix
tree (aka trie), which is well-suited for IP network membership checks
since networks are in fact a bitstring prefixes.

The specific representation is a crit-bit tree, but that choice was
purely based on implementation convenience - the chosen library is the
only one I could find that directly supports IP networks.

performance critical. Alas the existing code performs the check via a
linear scan of a list of networks. That is slow when there are more

AWS, a cluster can contain hundreds of networks, due to /32 networks
derived from interfaces with multiple IPs.

tree (aka trie), which is well-suited for IP network membership checks

ac5e379da2 vendor: update gobpf and tcptracer-bpf 
It will help to get missing kretprobe events during the ebpf tracker
initialization and missing connect & accept events, specially visible on
single-cores:
- https://github.com/weaveworks/tcptracer-bpf/pull/36
- https://github.com/iovisor/gobpf/pull/39

It makes use of a Linux patch that should be in Linux >= 4.12
(unreleased yet): https://github.com/iovisor/bcc/issues/1072#issuecomment-289777787
It falls back gracefully on current/older Linux kernels.

The new gobpf vendoring also includes other small fixes such as error
handling.

7541ad9c9c vendor: bump tcptracer-bpf 
We found out we were losing kretprobes sometimes because maxactive was set too
low[1]. This problem was more apparent in our GCE test environment because
the kernel was configured with `CONFIG_PREEMPT` not set and we're running
single-core VMs (see https://github.com/weaveworks/tcptracer-bpf/issues/24 for
more details).

Unfortunately, we can't set the maxactive explicitly from userspace. Alban
submitted a kernel patch to allow this[2].

This bumps tcptracer-bpf to include a workaround[3] for this issue in the
guess-offsets phase.

467ad884f6 Vendor github.com/containernetworking/cni/pkg/ns 
We will use this code to execute the code in some process' network
namespace.

I did the vendoring a bit differently, as gvt seems to be a bit dumb
about getting dependencies for test packages (it tried to vendor
ginkgo and gomega, since cni tests are using it).

Also, instead of vendoring golang.org/x/sys as
github.com/containernetworking/cni/vendor/golang.org/x/sys I moved it
to scope's vendor directory.
