According to https://github.com/golang/go/issues/5373, go recognizes
(and optimizes for) the following syntax:
```go
for i := range b {
b[i] = 0
}
```
so let's use it. Limited testing shows ~7.5x speed increase,
compared to the previously used syntax.

The reason is, either more than one name server is configured, or
nameserver was reconfigured in the middle of the test run. In any case,
different nameserver IP in an error messages should not be treated
as a failure, so let's strip those out.

`TestCleanupMountsAfterDaemonAndContainerKill` was supposedly written
when the container mounts were visible from the host. Currently they
all live in their own mount namespace and the only visible mount is
the tmpfs one for shareable /dev/shm inside the container (i.e.
/var/lib/docker/containers/<ID>/shm), which will no longer be there
in case of `--default-ipc-mode private` is used, and so the test will
fail. Add a check if any container mounts are visible from the host,
and skip the test if there are none, as there's nothing to check.
`TestCleanupMountsAfterDaemonCrash`: fix in a similar way, keeping
all the other checks it does, and skipping the "mounts gone" check
if there were no mounts visible from the host.
While at it, also fix the tests to use `d.Kill()` in order to not
leave behind a stale `docker.pid` files.

This test was added a long time ago, and over the years has proven to be flaky,
and slow. To address those issues, it was modified to;
- cleanup containers afterwards
- take clock-skew into account
- improve performance by parallelizing the container runs
- _reduce_ parallelization to address platform issues on Windows (twice..)
- adjust the test to take new limits into account
- adjust the test to account for more events being generated by containers
The last change to this test (made in ddae20c032058a0fd42c34c2e9750ee8f62) actually
broke the test, as it's now testing that all events sent by containers
(`numContainers*eventPerContainer`) are received, but the number of events that
is generated (17 containers * 7 events = 119) is less than the limit (256 events).
The limit is already covered by the `TestLogEvents` unit-test, that was added in
8d056423f8c433927089bd7eb6bc97abbc1ed502, and tests that the number of events
is limited to `eventsLimit`.
This patch removes the test, because it's not needed.

When compiling containerd binaries statically, linker rightfully

/tmp/go-build/net/_obj/cgo-gcc-prolog:46: warning: Using 'getaddrinfo'
in statically linked applications requires at runtime the shared
libraries from the glibc version used for linking
The same error appears for ctr, containerd, and containerd-stress
binaries.
The fix is to use Go's own DNS resolver functions, rather than
glibc's getaddrinfo() -- this option is turned on by `netgo` build tag.
See https://golang.org/pkg/net/ (look for "Name Resolution") for more
details.

This is a fix to regression in vfs graph driver introduced by
commit 7a1618ced359a3ac92 ("add quota support to VFS graphdriver").
On some filesystems, vfs fails to init with the following error:
> Error starting daemon: error initializing graphdriver: Failed to mknod
> /go/src/github.com/docker/docker/bundles/test-integration/d6bcf6de610e9/root/vfs/backingFsBlockDev:

As quota is not essential for vfs, let's ignore (but log as a warning) any error
from quota init.

Validation of Mounts was only performed on container _creation_, not on
container _start_. As a result, if the host-path no longer existed
when the container was started, a directory was created in the given
location.
This is the wrong behavior, because when using the `Mounts` API, host paths
should never be created, and an error should be produced instead.
This patch adds a validation step on container start, and produces an
error if the host path is not found.

Follow the conventions for namespace naming set out by other projects,
such as linuxkit and cri-containerd. Typically, they are some sort of
host name, with a subdomain describing functionality of the namespace.
In the case of linuxkit, services are launched in `services.linuxkit`.
In cri-containerd, pods are launched in `k8s.io`, making it clear that
these are from kubernetes.

With the contianerd 1.0 migration we now have strongly typed errors that
we can check for process not found.
We also had some bad error checks looking for `ESRCH` which would only
be returned from `unix.Kill` and never from containerd even though we
were checking containerd responses for it.
Fixes some race conditions around process handling and our error checks
that could lead to errors that propagate up to the user that should not.
