The additional []containerd.RemoteOpt is not used by ctr currently,
but planned to be used by nerdctl and also probably by stargz's ctr-remote.

Go 1.14 introduced a change to os.OpenFile (and syscall.Open) on Windows
that uses the permissions passed to determine if the file should be
created read-only or not. If the user-write bit (0200) is not set, then
FILE_ATTRIBUTE_READONLY is set on the underlying CreateFile call.
This is a significant change for any Windows code which created new
files and set the permissions to 0 (previously the permissions had no
affect, so some code didn't set them at all).
This change fixes the issue for the Windows service panic file. It will
now properly be created as a non-read-only file on Go 1.14+.
I have looked over the rest of the containerd code and didn't see other
places where this seems like an issue.

This allows filesystem-based ACLs for configuring access to the socket

This adds linux cni support to `ctr run` via a `--cni` flag. This uses the
default configuration for CNI on `ctr` to configure the network namespace for a
container.

Starting with go1.14, the go runtime hijacks SIGURG but with no way to
not send to other signal handlers.
In practice, we get this signal frequently.
I found this while testing out go1.15 with ctr and multiple execs with
only `echo hello`. When the process exits quickly, if the previous
commit is not applied, you end up with an error message that it couldn't
forward SIGURG to the container (due to the process being gone).

Previously the signal loop can end up racing with the process exiting.
Intead of logging and continuing the loop, exit early.

The flag was being silently ignored, and so no network setup was done,

We should never return a nil context because of the way this function is
typically used... e.g.
```
ctx, done, err := containerd.WithLease(ctx)
```
If there is an error `ctx` will be nil and any error handling may cause
an NPE if it tries to use `ctx`.

I missed this in my previous change: the ctr man page is also
in Section 8, because it's considered an administrative tool,
and containerd-config is related to containerd so updating these
as well.
This commit also fixes naming of the generated files, which was
hard-coded to .1.

Add `remotes/certutil` functions for loading `ca.crt`, `client.cert`, and `client.key` into `tls.Config` from a directory like `/etc/docker/certs.d/<hostname>.
See https://docs.docker.com/engine/security/certificates/ .
Client applications including CRI plugin are expected to configure the resolver using these functions.
As an example, the `ctr` tool is extended to support `ctr images pull --certs-dir=/etc/docker/certs.d example.com/foo/bar:baz`.
Tested with Harbor 1.8.

If runtime is not runc, it doesn't make sense to send runc Options

Seems to be that docs/man/ctr.1.md and docs/man/containerd.1.md were
removed in #3637 and were not updated correctly in the Makefile, leading
to build failures like:
