build the final stage of the Dockerfile (including COPY ...) if no BIND_DIR
is used.
if BIND_DIR is used, build the dev stage, thus skipping the COPY.

I noticed this in the build output;
```
16:05:07 [100%] Built target tini-static
16:05:07 + mkdir -p /build/
16:05:07 + cp tini-static /build//docker-init
```

These scripts explicitly use Bash, so we should be able to use
`[[` instead of `[` (which seems to be recommended).
Also added curly brackets to some bare variables, and quoted some paths.
This makes my IDE a bit more silent :-)

Using `errors.Errorf()` passes the error with the stack trace for
debugging purposes.
Also using `errdefs.InvalidParameter` for Windows, so that the API
will return a 4xx status, instead of a 5xx, and added tests for
both validations.

Description:
When using local volume option such as size=10G, type=tmpfs, if we provide wrong options, we could create volume successfully.
But when we are ready to use it, it will fail to start container by failing to mount the local volume(invalid option).
We should check the options at when we create it.

Many startup tasks have to run for each container, and thus using a
WaitGroup (which doesn't have a limit to the number of parallel tasks)
can result in Docker exceeding the NOFILE limit quite trivially. A more
optimal solution is to have a parallelism limit by using a semaphore.
In addition, several startup tasks were not parallelised previously
which resulted in very long startup times. According to my testing, 20K
dead containers resulted in ~6 minute startup times (during which time
Docker is completely unusable).
This patch fixes both issues, and the parallelStartupTimes factor chosen
(128 * NumCPU) is based on my own significant testing of the 20K
container case. This patch (on my machines) reduces the startup time
from 6 minutes to less than a minute (ideally this could be further
reduced by removing the need to scan all dead containers on startup --
but that's beyond the scope of this patchset).
In order to avoid the NOFILE limit problem, we also detect this
on-startup and if NOFILE < 2*128*NumCPU we will reduce the parallelism
factor to avoid hitting NOFILE limits (but also emit a warning since
this is almost certainly a mis-configuration).

In applyTar, if the driver's ApplyDiff returns an error, the function
returns early without calling io.Copy.
As a consequence, the resources (a goroutine and some buffers holding
the uncompressed image, the digest, etc...) allocated or referenced by
NewInputTarStream above aren't released, as the worker goroutine only
finishes when it finds EOF or a closed pipe.

A lack of check in the test code can lead to a panic due to
`len(ids)` being `0`.
Avoid the panic by adding appropriate checks. Note `Assert()` should be
used rather than `Check()` as if it fails we should not proceed with the
test.

Some messages are logged before the logrus format was set,
therefore resulting in inconsistent log-message formatting
during startup;
Before this patch;
