Reimplement 'pause' in C - smaller footprint all around
Statically links against musl. Size of amd64 binary is 3560 bytes.
I couldn't test the arm binary since I have no hardware to test it on, though I assume we want it to work on a raspberry pi.
This PR also adds the gcc5/musl cross compiling image used to build the binaries.

Correct the display of the output when e.g. starting the kubelet fails in the node e2e tests. This
change makes it display a string instead of an array of decimal values.

Framework support for node e2e.
This should let us port existing e2e tests to the node e2e suite, if the tests are node specific.
- Add keep-alive to ssh connection
- Don't try to stop services on image-based runs
- Increase jenkins ci timeout to 90 minutes to accomadate unpredictable go build times
- Remove spammy log statement

Fix PullImage and add corresponding node e2e test
Fixes#24101. This is a bug introduced by #23506, since ref #23563.
The root cause of #24101 is described [here](https://github.com/kubernetes/kubernetes/issues/24101#issuecomment-208547623).
This PR
1) Fixes#24101 by decoding the messages returned during pulling image, and return error if any of the messages contains error.
2) Add the node e2e test to detect this kind of failure.
3) Get present check out of `ConformanceImage.Remove()` and `ConformanceImage.Pull()`. Because sometimes we may expect error to occur in `PullImage()` and `RemoveImage()`, but even that doesn't happen, the `Present()` check will still return error and let the test pass.

Also /cc @resouer, because he is doing the image related functions refactoring.

e2e_node: port privileged pod tests from test/e2e/priviliged.go
The ported test is functionally the same as the original test.
The main difference between the two tests is that the original test relies on
`kubectl` to exec into the container, while the latter directly uses the REST
client of the apiserver. This avoids the need to copy kubectl to the node under
test.
