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docker/libtrust repository has been archived for several years now.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.

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 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.

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.

In case drvr.PutContent fails and returns error we'd have
some extra memory allocated, though in this case
(test with known size of the slice being iterated), that's fine.

Storage drivers may be able to take advantage of the hint to start
their walk more efficiently.
For S3: The API takes a start-after parameter. Registries with many
repositories can drastically reduce calls to s3 by telling s3 to only
list results lexographically after the last parameter.
For the fallback: We can start deeper in the tree and avoid statting
the files and directories before the hint in a walk. For a filesystem
this improves performance a little, but many of the API based drivers
are currently treated like a filesystem, so this drastically improves
the performance of GCP and Azure blob.
