Remove the old benchmark-tools directory, including
imports in the WORKSPACE file and associated bazel rules.
The new Golang benchmark-tools can be found at //test/benchmarks
and it is functionally equivalent, excepting syscall_test
which can be found in //test/perf/linux.

This change implements the Neighbor Unreachability Detection (NUD) state
machine, as per RFC 4861 [1]. The state machine operates on a single neighbor
in the local network. This requires the state machine to be implemented on each
entry of the neighbor table.
This change also adds, but does not expose, several APIs. The first API is for
performing basic operations on the neighbor table:
- Create a static entry
- List all entries
- Delete all entries
- Remove an entry by address
The second API is used for changing the NUD protocol constants on a per-NIC
basis to allow Neighbor Discovery to operate over links with widely varying
performance characteristics. See [RFC 4861 Section 10][2] for the list of
constants.
Finally, the last API is for allowing users to subscribe to NUD state changes.
See [RFC 4861 Appendix C][3] for the list of edges.

The go.mod dependency tree for the shim was somehow contradictory. After
resolving these issues (e.g. explicitly imported k8s 1.14, pulling a
specific dbus version), and adding all dependencies, the shim can now be
build as part of the regular bazel tree.
As part of this process, minor cleanup was done in all the source files:
headers were standardized (and include "The gVisor Authors" in addition
to the "The containerd Authors" if originally derived from containerd
sources), and comments were cleaned up to meet coding standards.
This change makes the containerd installation dynamic, so that multiple
versions can be tested, and drops the static installer for the VM image
itself.
This change also updates test/root/crictl_test.go and related utilities,
so that the containerd tests can be run on any version (and in cases
where it applies, they can be run on both v1 and v2 as parameterized
tests).
This change adds a layer of abstraction around the internal Docker APIs,
and eliminates all direct dependencies on Dockerfiles in the infrastructure.
A subsequent change will automated the generation of local images (with
efficient caching). Note that this change drops the use of bazel container
rules, as that experiment does not seem to be viable.

See tools/nogo/README.md.
The checkescape tool is able to perform recursive escape analysis, using the
actual generated binary to confirm the results produced by the compiler itself.
As an initial use case, this replaces the manual escape analysis tests used for
go_marshal, and validates that the CopyIn and CopyOut paths will not require
any allocation or stack splits.

ARM64 PTRACE_SYSEMU support was added to Linux kernal from
v5.3 and the corresponding support in golang is also enabled
in the latest org.golang/x/sys repository.

For everyone's joy, this is a tool that reopens issues that
have been closed, but are still referenced by TODOs in the
code. The idea is to run it in Kokoro nightly. Kokoro changes
are coming up next.

It would be preferrable to test iptables via syscall tests, but there are some
problems with that approach:
* We're limited to loopback-only, as syscall tests involve only a single
container. Other link interfaces (e.g. fdbased) should be tested.
* We'd have to shell out to call iptables anyways, as the iptables syscall
interface itself is too large and complex to work with alone.
* Running the Linux/native version of the syscall test will require root, which
is a pain to configure, is inherently unsafe, and could leave host iptables
misconfigured.
Using the go_test target allows there to be no new test runner.

This has adapted for use with bazel from the original commit
a26e93769ebefd82593a43e22fb13a09717cfa6d.
In particular, the style has been made consistent with internal python style
guidelines, and the packages (including the main entrypoint) have been
refactored in order to allow bazel testing targets.

absl flags are more modern and we can easily depend on them directly.
The repo now successfully builds with --incompatible_load_cc_rules_from_bzl.

This fixes the RBE warning:

The new version has a change in behavior when using a custom platform:
* Old behavior: rules that don't require a toolchain used host_platform, no
matter what execution platforms are specified.
* New behavior: rules that don't require a toolchain use standard platform
resolution that starts with execution platforms.
As part of this change, we cannot use the "extra_exectution_platforms" flag
provided by the default bazelrc. I got rid of the default bazelrc file, and
made our custom .bazelrc as minimal as possible.

This introduces two new types of Emitters:
1. MultiEmitter, which will forward events to other registered Emitters, and
2. RateLimitedEmitter, which will forward events to a wrapped Emitter, subject
to given rate limits.
The methods in the eventchannel package itself act like a multiEmitter, but is
not actually an Emitter. Now we have a DefaultEmitter, and the methods in
eventchannel simply forward calls to the DefaultEmitter.
The unimplemented syscall handler now uses a RateLimetedEmitter that wraps the
DefaultEmitter.

Adds simple introspection for syscall compatibility information to Linux/AMD64.
Syscalls registered in the syscall table now have associated metadata like
name, support level, notes, and URLs to relevant issues.
Syscall information can be exported as a table, JSON, or CSV using the new
'runsc help syscalls' command. Users can use this info to debug and get info
on the compatibility of the version of runsc they are running or to generate
documentation.
