Both tty.resize and notifySocket.setupSocket return an error which isn't
handled in the caller. Fix this and either log or propagate the errors.

To make sure that `make release` doesn't suddenly break after we've cut
a release, smoke-test the release scripts. The script won't fail if GPG
keys aren't found, so running in CI shouldn't be a huge issue.

This script is far easier to use than the previous `make release`
target, not to mention that it also automatically signs all of the
artefacts and makes everything really easy to do for maintainers.

state.json should be a reflection of the container's
realtime state, including resource configurations,
so we should update state.json after updating container
resources.

Go has supported PIC builds for a while now, and given the security
benefits of using PIC binaries we should really enable them. There also
appears to be some indication that non-PIC builds have been interacting
oddly on ppc64le (the linker cannot load some shared libraries), and
using PIC builds appears to solve this problem.

The "go build -i" invocation may slightly help with incremental
recompilation, but it will cause builds to fail if $GOROOT is not
writeable by the current user. While this does appear to work sometimes,
it's a concern for external build systems where "-i" causes build errors
for no real gain.
Given the size of the runc project, --install is not really giving us
much anyway.

With this runC also uses RPC to ask CRIU for its version. CRIU supports
a VERSION RPC since CRIU 3.0 and using the RPC interface does not
require parsing the console output of CRIU (which could change anytime).
For older CRIU versions which do not yet have the VERSION RPC runC falls
back to its old CRIU output parsing mode.
Once CRIU 3.0 is the minimum version required for runC the old code can
be removed.

This includes lazy_pages for the upcoming lazy migration support.

To use the CRIU VERSION RPC the criuSwrk function is adapted to work
with CriuOpts set to 'nil' as CriuOpts is not required for the VERSION
RPC.
Also do not print c.criuVersion if it is '0' as the first RPC call will
always be the VERSION call and only after that the version will be
known.

If the version of criu has already been determined there is no need to
ask criu for the version again. Use the value from c.criuVersion.
v2:
* reduce unnecessary code movement in the patch series
* factor out the criu version parsing into a separate function
Signed-off-by: Adrian Reber <areber@redhat.com>
The checkCriuVersion function used a string to specify the minimum
version required. This is more comfortable for an external interface
but for an internal function this added unnecessary complexity. This
changes to version string like '1.5.2' to an integer like 10502. This is
already the format used internally in the function.

go's switch statement doesn't need an explicit break. Remove it where
that is the case and add a comment to indicate the purpose where the
removal would lead to an empty case.

This removes usages of docker/pkg/term to set raw terminal, handle interrupt

This moves all console code to use github.com/containerd/console library to
handle console I/O. Also move to use EpollConsole by default when user requests
a terminal so we can still cope when the other side temporarily goes away.
