This commit make the S3 driver chunk size constants more straightforward
to understand -- instead of remembering the bit shifts we make this more
explicit.
We are also updating append parameter to the `(writer).Write` to follow
the new convention we are trying to establish.

Nowadays there are much, much better UUID implementations to choose
from, such as github.com/google/uuid. Prevent external users from
importing our bespoke implementation so that we can change or migrate
away from it internally without introducing breaking changes.

Our registry client is not currently in a good place to be used as the
reference OCI Distribution client implementation. But the registry proxy
currently depends on it. Make the registry client internal to the
distribution application to remove it from the API surface area (and any
implied compatibility promises) of distribution/v3@v3.0.0 without
breaking the proxy.

docker/libtrust repository has been archived for several years now.
This commit replaces all the libtrust JWT machinery with go-jose/go-jose module.
Some of the code has been adopted from libtrust and adjusted for some of
the use cases covered by the token authorization flow especially in the
tests.

This commit changes storagedriver.Filewriter interface
by adding context.Context as an argument to its Commit
func.
We pass the context appropriately where need be throughout
the distribution codebase to all the writers and tests.
S3 driver writer unfortunately must maintain the context
passed down to it from upstream so it contnues to
implement io.Writer and io.Closer interfaces which do not
allow accepting the context in any of their funcs.

Small refactoring of storagedriver errors.
We change the Enclosed field to Detail and make sure
Errors get properly serialized to JSON.
We also add tests.

Nested files aren't supported on MinIO, and as our storage layout is
filesystem based, we don't actually use nest files in the code.
Remove the test so that we can support MinIO.

This fixes some of the tests for minio.
The walk tests needs a version of minio that contains https://github.com/minio/minio/pull/18099
The storage classes minio supports are a subset of the s3 classes.

This commit removes some `conn` parameters of private functions, which can
be obtain from the struct itself. The `conn` is for the old `redisgo` library,
which is replaced by `go-redis` in #4019.

In terms of results, a`manifestTagsPathSpec{ name: "repo" }` equals
`manifestTagPathSpec{ name: "repo", tag: "" }`, but from the intention,
the `manifestTagsPathSpec` should be used.

This commit cleans up and attempts to optimise the performance of image push in S3 driver.
There are 2 main changes:
* we refactor the S3 driver Writer where instead of using separate bytes
slices for ready and pending parts which get constantly appended data
into them causing unnecessary allocations we use optimised bytes
buffers; we make sure these are used efficiently when written to.
* we introduce a memory pool that is used for allocating the byte
buffers introduced above
These changes should alleviate high memory pressure on the push path to S3.

Add two new checks to the testsuite that check
the driver can handle zero byte files and appends to zero
byte files correctly

The SuccessStatus acted on the response's status code, and was used to return
early, before checking the same status code with HandleErrorResponse.
This patch combines both functions into a HandleHTTPResponseError, which
returns an error for "non-success" status-codes, which simplifies handling
of responses, and makes some logic slightly more idiomatic.

It was used for signing schema v1 manifests in tests which have now been
removed so there is no point in keeping these there anymore.

Use the non-exported function to all errors; there's currently no external
consumers of this function (perhaps it should be deprecated).
