With the ticker this could end up just doing back-to-back checks, which
isn't really what we want here.
Instead use a sleep to ensure we actually sleep for the desired
interval.

In info, we only need the number of images, but `CountImages` was
getting the whole map of images and then grabbing the length from that.
This causes a lot of unnecessary CPU usage and memory allocations, which
increases with O(n) on the number of images.

The re-coalesces the daemon stores which were split as part of the
original LCOW implementation.
This is part of the work discussed in https://github.com/moby/moby/issues/34617,

This PR has the API changes described in https://github.com/moby/moby/issues/34617.
Specifically, it adds an HTTP header "X-Requested-Platform" which is a JSON-encoded
OCI Image-spec `Platform` structure.
In addition, it renames (almost all) uses of a string variable platform (and associated)
methods/functions to os. This makes it much clearer to disambiguate with the swarm
"platform" which is really os/arch. This is a stepping stone to getting the daemon towards
fully multi-platform/arch-aware, and makes it clear when "operating system" is being
referred to rather than "platform" which is misleadingly used - sometimes in the swarm
meaning, but more often as just the operating system.
Use strongly typed errors to set HTTP status codes.
Error interfaces are defined in the api/errors package and errors
returned from controllers are checked against these interfaces.
Errors can be wraeped in a pkg/errors.Causer, as long as somewhere in the
line of causes one of the interfaces is implemented. The special error
interfaces take precedence over Causer, meaning if both Causer and one
of the new error interfaces are implemented, the Causer is not
traversed.

This showed up in a recent profile.
Search doesn't need to take a lock on the store, because digestset has
its own locking.
Some other methods can get by with a read lock instead of an exclusive
lock.

Issue Description:
* 1. Saving more than one images, `docker save -o a.tar aaa bbb`
* 2. Delete the last image which in saving progress. `docker rmi bbb`
Espected:
Saving images operation shouldn't be disturbed. But the real result is that failed to
save image and get an error as below:
`Error response from daemon: open
/var/lib/docker/image/devicemapper/imagedb/content/sha256/7c24e4d533a76e801662ad1b7e6e06bc1204f80110b5623e96ba2877c51479a1:
no such file or directory`
Analysis:
1. While saving more than one images, it will get all the image info from reference/imagestore,
and then using the `cached data` to save the images to a tar file.
2. But this process doesn't have a resource lock, if a deletion operation comes, the image will be deleted,
so saving operation will fail.
Solution:
When begin to save an image, `Get` all the layers first. then the
deletion operation won't delete the layers.

Instead of mutating and reverting, just create a copy and pass the copy
around.
Add a unit test for builder dispatcher.run
Fix two test failures
Fix image history by adding a CreatedBy to commit options. Previously the
createdBy field was being created by modifying a reference to the runConfig that
was held from when the container was created.
Fix a test that expected a trailing slash. Previously the runConfig was being
modified by container create. Now that we're creating a copy of runConfig
instead of sharing a reference the runConfig retains the trailing slash.

Mostly, they always have been. Most regular expressions were implemented
as `[\w][\w.-]{0,127]`, which actually allows 128 characters, since we
start with a character in the first expression.
This "fact" has been backported to the existing specifications where
length is mentioned. For the most part, no ill-effects should come of
this, unless someone has optimized to hold the length of a tag in a 7
bit integer.

I noticed that we're using a homegrown package for assertions. The
functions are extremely similar to testify, but with enough slight
differences to be confusing (for example, Equal takes its arguments in a
different order). We already vendor testify, and it's used in a few
places by tests.
I also found some problems with pkg/testutil/assert. For example, the
NotNil function seems to be broken. It checks the argument against
"nil", which only works for an interface. If you pass in a nil map or
slice, the equality check will fail.
In the interest of avoiding NIH, I'm proposing replacing
pkg/testutil/assert with testify. The test code looks almost the same,
but we avoid the confusion of having two similar but slightly different
assertion packages, and having to maintain our own package instead of
using a commonly-used one.
In the process, I found a few places where the tests should halt if an
assertion fails, so I've made those cases (that I noticed) use "require"
instead of "assert", and I've vendored the "require" package from
testify alongside the already-present "assert" package.

Remove forked reference package. Use normalized named values
everywhere and familiar functions to convert back to familiar
strings for UX and storage compatibility.
Enforce that the source repository in the distribution metadata
is always a normalized string, ignore invalid values which are not.
Update distribution tests to use normalized values.
