Something seems broken on azure/azure sdk side - it is currently not
possible to copy a blob of type AppendBlob using `CopyFromURL`.
Using the AppendBlob client via NewAppendBlobClient does not work
either.
According to Azure the correct way to do this is by using
StartCopyFromURL. Because this is an async operation, we need to do
polling ourselves. A simple backoff mechanism is used, where during each
iteration, the configured delay is multiplied by the retry number.
Also introduces two new config options for the Azure driver:
copy_status_poll_max_retry, and copy_status_poll_delay.

It is desirable to remove Platform from distribution.Descriptor because it doesn't really belong there. However this would be a further breaking change because the References() call would no longer be returning plaform information when it reurns descriptors of manifests, which is started to for OCI Indices after c94f288 and this feature was added to Docker Manifest Lists in 1a059fe. I don't want to take away something people clearly want.

Introduced a Catalog entry in the configuration struct. With it,
it's possible to control the maximum amount of entries returned
by /v2/catalog (`GetCatalog` in registry/handlers/catalog.go).
It's set to a default value of 1000.
`GetCatalog` returns 100 entries by default if no `n` is
provided. When provided it will be validated to be between `0`
and `MaxEntries` defined in Configuration. When `n` is outside
the aforementioned boundary, an error response is returned.
`GetCatalog` now handles `n=0` gracefully with an empty response
as well.

Move implementation of the index from the manifestlist package to the ocischema package so that other modules making empty imports support the manifest types their authors would expect. This is a breaking change to distribution as a library but not the registry.
As OCI 1.0 released the manifest and index together, that is a good package from which to initialise both manifests. The docker manifest and manifest list remain in separate packages because one was released later.
The image index and manifest list still share common code in many functions not intended for import by other modules.

This is an edge case when we are trying to upload an empty chunk of data using
a MultiPart upload. As a result we are trying to complete the MultipartUpload
with an empty slice of `completedUploadedParts` which will always lead to 400
being returned from S3 See: https://docs.aws.amazon.com/sdk-for-go/api/service/s3/#CompletedMultipartUpload
Solution: we upload an empty i.e. 0 byte part as a single part and then append it
to the completedUploadedParts slice used to complete the Multipart upload.

The loop that iterates over paginated lists of S3 multipart upload parts
appears to be using the wrong variable in its loop condition. Nothing
inside the loop affects the value of `resp.IsTruncated`, so this loop
will either be wrongly skipped or loop forever.
It looks like this is a regression caused by commit
7736319f2e. The return value of
`ListMultipartUploads` used to be assigned to a variable named `resp`,
but it was renamed to `partsList` without updating the for loop
condition.
I believe this is causing an error we're seeing with large layer uploads
at commit time:
upload resumed at wrong offset: 5242880000 != 5815706782
Missing parts of the multipart S3 upload would cause an incorrect size
calculation in `newWriter`.

Previously we used a custom Transport in order to modify the user agent header.
This prevented the AWS SDK from being able to customize SSL and other client TLS
parameters since it could not understand the Transport type.
Instead we can simply use the SDK function MakeAddToUserAgentFreeFormHandler to
customize the UserAgent if necessary and leave all the TLS configuration to the
AWS SDK.
The only exception being SkipVerify which we have to handle, but we can set it
onto the standard http.Transport which does not interfere with the SDKs ability
to set other options.

Currently, "response completed with error" log lines include an
`auth.user.name` key, but successful "response completed" lines do not
include this, because they are logged a few stack frames up where
`auth.user.name` is not present on the `Context`. Move the successful
request logging inside the `dispatcher` closure, where the logger on the

Go 1.18 and up now provides a strings.Cut() which is better suited for
splitting key/value pairs (and similar constructs), and performs better:
```go
func BenchmarkSplit(b *testing.B) {
b.ReportAllocs()
data := []string{"12hello=world", "12hello=", "12=hello", "12hello"}
for i := 0; i < b.N; i++ {
for _, s := range data {
_ = strings.SplitN(s, "=", 2)[0]
}
}
}
func BenchmarkCut(b *testing.B) {
b.ReportAllocs()
data := []string{"12hello=world", "12hello=", "12=hello", "12hello"}
for i := 0; i < b.N; i++ {
for _, s := range data {
_, _, _ = strings.Cut(s, "=")
}
}
}
```
BenchmarkSplit
BenchmarkSplit-10 8244206 128.0 ns/op 128 B/op 4 allocs/op
BenchmarkCut
BenchmarkCut-10 54411998 21.80 ns/op 0 B/op 0 allocs/op
While looking at occurrences of `strings.Split()`, I also updated some for alternatives,
or added some constraints;
- for cases where an specific number of items is expected, I used `strings.SplitN()`
with a suitable limit. This prevents (theoretical) unlimited splits.
- in some cases it we were using `strings.Split()`, but _actually_ were trying to match
a prefix; for those I replaced the code to just match (and/or strip) the prefix.

(*App).context, called in the HTTP handler on each request, creates a
URLBuilder, which involves calling Router(). This shows up in profiles a
hot spot because it involves compiling the regexps which define all the
routes. For efficiency, cache the router and return the same object each
time.
It appears to be safe to reuse the router because GetRoute is the only
method ever called on the returned router object.
