This brings freebsd in line with Darwin, ie it builds, but some parts may not yet
be fully functional. There is now a WIP `runc` port for FreeBSD at
https://github.com/clovertrail/runc/tree/1501-SupportOnFreeBSD so should be able
to test further.

There is still a special case where the client side fails to open or
load causes things to be slow and the shim can lock up when this
happens. This adds a timeout to the context for this case to abort fifo
creation.

logrus v1.0.3 was the first release that include the change in
terminal_windows.go that stops exec'ing "cmd ver" to obtain the version
information and rather uses the x/sys/crypto/terminal.IsTerminal on the
console fd. On Windows this is a significant performance difference to
avoid the additional process activation of the "cmd ver" for each
invocation of the shim/runhcs executables.

There were races with the way process states. This displayed in ways,
especially around pausing the container for atomic operations. Users
would get errors like, cannnot delete container in paused state and
such.
This can be eaisly reproduced with `docker` and the following command:
```bash
> (for i in `seq 1 25`; do id=$(docker create alpine usleep 50000);docker start $id;docker commit $id;docker wait $id;docker rm $id; done)
```
This two issues that this fixes are:
* locks must be held by the owning process, not the state operations.
* If a container ends up being paused but before the operation
completes, the process exists, make sure we resume the container before
setting the the process as exited.

add '-id' flag when start container with io.containerd.runc.v1 shim, or user
can not get container-shim relation from 'ps -ef',like
```
/usr/bin/containerd-shim-runc-v1 -namespace default -address
/run/containerd/containerd.sock -publish-binary /usr/bin/containerd
```

1. avoid dead lock during kill, fetch allProcesses before handle events
2. use argu's ctx instead of context.Backgroud() in openlog

Fixes#2709
This increases the buffer size for process exit subscribers. It also
implements a non-blocking send on the subscriber channel. It is better
to drop an exit even than it is to block a shim for one slow subscriber.

On Windows because of the way the log pipe is forwarded to the shim there is a
condition where the pipe listener may not yet be active when a client tries to
connect. To handle this case we allow polling on the file and rety on pipe not
found. This limits the pipe not found retry to 5 seconds but leaves the connect
timeout alone as if there is a listener we want to connect to it normally.

Revendors to Microsoft/hcsshim v0.7.5 that added support for logging all
runhcs.exe commands via Windows named pipes. This now launches all runhcs.exe
commands and forwards debug logging to the containerd-shim-runhcs log when
with --debug.

1. Fixes bugs in ctr run that were introduced by 1d9b969
2. Adds support for the --isolated flag that runs Windows HyperV
cotainers instead of process isolated containers on Windows.

func (e *execProcess) delete(ctx context.Context) error {
e.wg.Wait()
...
}
delete exec process will wait for io copy finish, if wait here,
other process can not get lock of shim service.
1. apply lock around s.transition() calls in the Delete methods.
2. put lock after wait io copy in exec Delete.
