`Daemon.getPidContainer()` was wrapping the error-message with a message
("cannot join PID of a non running container") that did not reflect the
actual reason for the error; `Daemon.GetContainer()` could either return
an invalid parameter (invalid / empty identifier), or a "not found" error
if the specified container-ID could not be found.
In the latter case, we don't want to return a "not found" error through
the API, as this would indicate that the container we're _starting_ was
not found (which is not the case), so we need to convert the error into
an `errdefs.ErrInvalidParameter` (the container-ID specified for the PID
namespace is invalid if the container doesn't exist).
This logic is similar to what we do for IPC namespaces. which received
a similar fix in c3d7a0c603.
This patch updates the error-types, and moves them into the getIpcContainer
and getPidContainer container functions, both of which should return
an "invalid parameter" if the container was not found.
It's worth noting that, while `WithNamespaces()` may return an "invalid
parameter" error, the `start` endpoint itself may _not_ be. as outlined
in commit bf1fb97575, starting a container
that has an invalid configuration should be considered an internal server
error, and is not an invalid _request_. However, for uses other than
container "start", `WithNamespaces()` should return the correct error
to allow code to handle it accordingly.

This utility was only used for a single test, and it was very limited
in functionality as it only allowed for a certain error-string to be
matched.
Let's change it into a more generic function; a helper that allows a
container to be created from a `TestContainerConfig` (which can be
constructed using `NewTestConfig`) and that returns the response from
client.ContainerCreate(), so that any result from that can be tested,
leaving it up to the test to check the results.

The `client` variable was colliding with the `client` import. In some cases
the confusing `cli` name (it's not the "cli") was used. Given that such names
can easily start spreading (through copy/paste, or "code by example"), let's
make a one-time pass through all of them in this package to use the same name.

The original code in container.Exec was potentially leaking the copy
goroutine when the context was cancelled or timed out. The new
`demultiplexStreams()` function won't return until the goroutine has
finished its work, and to ensure that it takes care of closing the
hijacked connection.

I noticed this was always being skipped because of race conditions
checking the logs.
This change adds a log scanner which will look through the logs line by
line rather than allocating a big buffer.
Additionally it adds a `poll.Check` which we can use to actually wait
for the desired log entry.

Calling function returned from setupTest (which calls testEnv.Clean) in
a defer block inside a test that spawns parallel subtests caused the
cleanup function to be called before any of the subtest did anything.
Change the defer expressions to use `t.Cleanup` instead to call it only
after all subtests have also finished.
This only changes tests which have parallel subtests.

The daemon.lazyInitializeVolume() function only handles restoring Volumes
if a Driver is specified. The Container's MountPoints field may also
contain other kind of mounts (e.g., bind-mounts). Those were ignored, and
don't return an error; 1d9c8619cd/daemon/volumes.go (L243-L252C2)
However, the prepareMountPoints() assumed each MountPoint was a volume,
and logged an informational message about the volume being restored;
1d9c8619cd/daemon/mounts.go (L18-L25)
This would panic if the MountPoint was not a volume;

This adds an additional interval to be used by healthchecks during the
start period.
Typically when a container is just starting you want to check if it is
ready more quickly than a typical healthcheck might run. Without this
users have to balance between running healthchecks to frequently vs
taking a very long time to mark a container as healthy for the first
time.

Multiple daemons starting/running concurrently can collide with each
other when editing iptables rules. Most integration tests which opt into
parallelism and start daemons work around this problem by starting the
daemon with the --iptables=false option. However, some of the tests
neglect to pass the option when starting or restarting the daemon,
resulting in those tests being flaky.
Audit the integration tests which call t.Parallel() and (*Daemon).Stop()
and add --iptables=false arguments where needed.
