When following a journal-based log, it was possible for the worker
goroutine, which reads the journal using the journal context and sends
entry data down the message channel, to be scheduled after the function
which started it had returned. This could create problems, since the
invoking function was closing the journal context object and message
channel before it returned, which could trigger use-after-free segfaults
and write-to-closed-channel panics in the worker goroutine.
Make the cleanup in the invoking function conditional so that it's only
done when we're not following the logs, and if we are, that it's left to
the worker goroutine to close them.

The journald log reader keeps a map of following readers so that it can
close them properly when the journald reader object itself is closed,
but it was possible for its worker goroutine to be scheduled so that the
worker attempted to remove a reader from the map before the reader had
been added to the map. This patch adds the item to the map before
starting the goroutine which is expected to eventually remove it.

The GCP logging driver is calling out to GCP cloud service on package
init.
This is regardless if you are using GCP logging or not.
This change makes this happen on the first invocation of a new GCP
logging driver instance instead.

This fixes problems encountered when running with a remapped root (the
syscalls related to the metadata directory will fail under user
namespaces). Using 0711 rather than 0701 (which solved the problem
previously) fixes the issue.

Following #19995 and #17409 this PR enables skipping userns re-mapping
when creating a container (or when executing a command). Thus, enabling
privileged containers running side by side with userns remapped
containers.
The feature is enabled by specifying ```--userns:host```, which will not
remapped the user if userns are applied. If this flag is not specified,
the existing behavior (which blocks specific privileged operation)
remains.

When I use `docker exec -ti test ls`, I got error:
```
ERRO[0035] Handler for POST /v1.23/exec/9677ecd7aa9de96f8e9e667519ff266ad26a5be80e80021a997fff6084ed6d75/resize returned error: bad file descriptor
```
It's because `POST /exec/<id>/start` and
`POST /exec/<id>/resize` are asynchronous, it is
possible that exec process finishes and ternimal
is closed before resize. Then `console.Fd()` will
get a large invalid number and we got the above
error.
Fix it by adding synchronization between exec and
resize.

Now what we provide dynamic binaries for all plaforms,
we shouldn't try to run docker without udev sync support.
This change changes the previous warning to an Error,
unless the user explicitly overrides the warning, in
which case they're at their own risk.
