rt_sigreturn is required for signal handling (e.g., SIGSEGV for nil-pointer
dereference). Before this, nil-pointer dereferences cause a syscall violation
instead of a panic.

Options that do not change mount behavior inside the Sentry are
irrelevant and should not be used when looking for possible
incompatibilities between master and slave mounts.

Adds two tests. One to make sure that $HOME is set when starting a container
via 'docker run' and one to make sure that $HOME is set for each container in a
multi-container sandbox.
Issue #701

'docker exec' was getting CAP_NET_RAW even when --net-raw=false
because it was not filtered out from when copying container's
capabilities.

BUILD:85:1: in _pkg_deb rule //runsc:runsc-debian: target
'//runsc:runsc-debian' depends on deprecated target
'@bazel_tools//tools/build_defs/pkg:make_deb': The internal version of
make_deb is deprecated. Please use the replacement for pkg_deb from
https://github.com/bazelbuild/rules_pkg/blob/master/pkg.

Filter installation has been streamlined and functions renamed.
Documentation has been fixed to be standards compliant, and missing
documentation added. gofmt has also been applied to modified files.
We need to include the `--stamp` flag in `tools/workspace_status.sh` for
the version to be picked up by the linker. Not sure why.
Also changes the VERSION string to STABLE_VERSION, which will cause the
program to be re-linked if the string changes.
Fixes#830
This is done because the root container for CRI is the infrastructure (pause)
container and always gets a low oom_score_adj. We do this to ensure that only
the oom_score_adj of user containers is used to calculated the sandbox
oom_score_adj.
Implemented in runsc rather than the containerd shim as it's a bit cleaner to
implement here (in the shim it would require overwriting the oomScoreAdj and
re-writing out the config.json again). This processing is Kubernetes(CRI)
specific but we are currently only supporting CRI for multi-container support
anyway.

Some processes are reparented to the root container depending
on the kill order and the root container would not reap in time.
So some zombie processes were still present when the test checked.
Fix it by running the second container inside a PID namespace.

The simple test script has gotten out of control. Shard this script into
different pieces and attempt to impose order on overall test structure. This
change helps lay some of the foundations for future improvements.
* The runsc/test directories are moved into just test/.
* The runsc/test/testutil package is split into logical pieces.
* The scripts/ directory contains new top-level targets.
* Each test is now responsible for building targets it requires.
* The install functionality is moved into `runsc` itself for simplicity.
* The existing kokoro run_tests.sh file now just calls all (can be split).
After this change is merged, I will create multiple distinct workflows for
Kokoro, one for each of the scripts currently targeted by `run_tests.sh` today,
which should dramatically reduce the time-to-run for the Kokoro tests, and
provides a better foundation for further improvements to the infrastructure.

This used to be the case, but regressed after a recent change.
Also made a few fixes around it and clean up the code a bit.

This commit adds support for detecting the socket file type, connecting
to a Unix Domain Socket, and providing bidirectional communication
(without file descriptor transfer support).
