In case aufs driver is not supported because supportsAufs() said so,
it is not possible to get a real reason from the logs.
To fix, log the error returned.
Note we're not using WithError here as the error message itself is the
sole message we want to print (i.e. there's nothing to add to it).

Simplify the code by using a single logger instance.
While at it, use WithError in Umount.

ext4 support d_type by default, but filetype feature is a tunable so
there is still a chance to disable it for some reasons. In this case,
print additional message to explicitly tell how to support d_type.

In cases where a logging plugin has crashed when the daemon tries to
copy the container stdio to the logging plugin it returns a broken pipe
error and any log entries that occurr while the plugin is down are lost.
Fix this by opening read+write in the daemon so logs are not lost while
the plugin is down.

- Check errors.Cause(err) when comparing errors
- Fix bug where oldest log file is not actually removed. This in
particular causes issues when compression is enabled. On rotate it just
overwrites the data in the log file corrupting it.
- Use O_TRUNC to open new gzip files to ensure we don't corrupt log
files as happens without the above fix.

Closing the log driver was in a defer meanwhile logs are
collected asyncronously, so the log driver was being closed before reads

The overlay storage driver currently does not support any option, but was silently
ignoring any option that was passed.
This patch verifies that no options are passed, and if they are passed will produce
an error.

These network operations really don't have anything to do with the
container but rather are setting up the networking.
Ideally these wouldn't get shoved into the daemon package, but doing
something else (e.g. extract a network service into a new package) but
there's a lot more work to do in that regard.
In reality, this probably simplifies some of that work as it moves all
the network operations to the same place.

A recent optimization in getSourceMount() made it return an error
in case when the found mount point is "/". This prevented bind-mounted
volumes from working in such cases.
A (rather trivial but adeqate) unit test case is added.

It does not make sense to copy a slice element by element, then discard
the source one. Let's do copy in place instead which is way more
efficient.

When then non-blocking mode is specified, awslogs will:
- No longer potentially block calls to logstream.Log(), instead will
return an error if the awslogs buffer is full. This has the effect of
dropping log messages sent to awslogs.Log() that are made while the
buffer is full.
- Wait to initialize the log stream until the first Log() call instead of in
New(). This has the effect of allowing the container to start in
the case where Cloudwatch Logs is unreachable.
Both of these changes require the --log-opt mode=non-blocking to be
explicitly set and do not modify the default behavior.

Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".
Many vendored packages still use x/net/context, so vendor entry remains
for now.
