This commit removes gogoproto.enumvalue_customname,
gogoproto.goproto_enum_prefix and gogoproto.enum_customname.
All of them make proto-generated Go code more idiomatic, but we already
don't use these enums in our external-surfacing types and they are anyway
not supported by Google's official toolchain (see #6564).

Bundle directory permissions should be 0700 by default. On Linux with
user namespaces enabled, the remapped root also needs access to the
bundle directory. In this case, the bundle directory is modified to
0710 and group ownership is changed to the remapped root group.
Port of the same change for the v2 runtime

In linux platform, the shim server always listens on the socket before
the containerd task manager dial it. It is unlikely that containerd task
manager should handle reconnect because the shim can't restart. For this
case, the containerd task manager should fail fast if there is ENOENT or
ECONNREFUSED error.
And if the socket file is deleted during cleanup the exited task, it
maybe cause that containerd task manager takes long time to reload the
dead shim. For that task.v2 manager, the race case is like:
```
TaskService.Delete
TaskManager.Delete(runtime/v2/manager.go)
shim.delete(runtime/v2/shim.go)
shimv2api.Shutdown(runtime/v2/task/shim.pb.go)
<- containerd has been killed or restarted somehow
bundle.Delete
```
The shimv2api.Shutdown will cause that the shim deletes socket file
(containerd-shim-runc-v2 does). But the bundle is still there. During
reloading, the containerd will wait for the socket file appears again
in 100 seconds. It is not reasonable. The Reconnect should prevent this
case by fast fail.
Closes: #5648.
Fixes: #5597.

Go 1.15.7 contained a security fix for CVE-2021-3115, which allowed arbitrary
code to be executed at build time when using cgo on Windows. This issue also
affects Unix users who have “.” listed explicitly in their PATH and are running
“go get” outside of a module or with module mode disabled.
This issue is not limited to the go command itself, and can also affect binaries
that use `os.Command`, `os.LookPath`, etc.
From the related blogpost (ttps://blog.golang.org/path-security):
> Are your own programs affected?
>
> If you use exec.LookPath or exec.Command in your own programs, you only need to
> be concerned if you (or your users) run your program in a directory with untrusted
> contents. If so, then a subprocess could be started using an executable from dot
> instead of from a system directory. (Again, using an executable from dot happens
> always on Windows and only with uncommon PATH settings on Unix.)
>
> If you are concerned, then we’ve published the more restricted variant of os/exec
> as golang.org/x/sys/execabs. You can use it in your program by simply replacing
This patch replaces all uses of `os/exec` with `golang.org/x/sys/execabs`. While
some uses of `os/exec` should not be problematic (e.g. part of tests), it is
probably good to be consistent, in case code gets moved around.

oom_score_adj must be in the range -1000 to 1000. In AdjustOOMScore if containerd's score is already at the maximum value we should set that value for the shim instead of trying to set 1001 which is invalid.

Currently the shims only support starting the logging binary process if the
io.Creator Config does not specify Terminal: true. This means that the program
using containerd will only be able to specify FIFO io when Terminal: true,
rather than allowing the shim to fork the logging binary process. Hence,
containerd consumers face an inconsistent behavior regarding logging binary
management depending on the Terminal option.
Allowing the shim to fork the logging binary process will introduce consistency
between the running container and the logging process. Otherwise, the logging
process may die if its parent process dies whereas the container will keep
running, resulting in the loss of container logs.
