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
context automatically includes this key.

golang.org/x/net contains a fix for CVE-2022-41717, which was addressed
in stdlib in go1.19.4 and go1.18.9;
> net/http: limit canonical header cache by bytes, not entries
>
> An attacker can cause excessive memory growth in a Go server accepting
> HTTP/2 requests.
>
> HTTP/2 server connections contain a cache of HTTP header keys sent by
> the client. While the total number of entries in this cache is capped,
> an attacker sending very large keys can cause the server to allocate
> approximately 64 MiB per open connection.
>
> This issue is also fixed in golang.org/x/net/http2 v0.4.0,
> for users manually configuring HTTP/2.

commit 9337b8df66 rewrote the fuzzers to
native go fuzzers, so the script was no longer needed. With this, the
script directory is no longer used, so we can remove it.

This is just cosmetic; alighn the fields with the order in which they appear
in the struct (and JSON output).

I am looking at aligning the types defined in this repository with the
OCI image specification, and potentially exchanging local types with
those from the specification.
This patch is a stepping-stone towards that effort, but as this changes
the format of the serialized JSON, I wanted to put this up first before
proceeding with the other work in case there are concerns.

Docker Image manifest v2, schema version 1 is deprecated since 2015, when
manifest v2, schema version 2 was introduced (2e3f4934a7).
Users should no longer use this specification other than for backward
compatibility.

This makes them easier to find between the non-exported ones, and puts
them as separate sections in the generated docs. While updating, also
extended documentation for some to be more descriptive.

Localhost is treated special when parsing references, and always considered
to be a domain, despite not having a "." nor a ":port". Adding a const for
this, to allow documenting this special case (making it more visible).

This pattern was used in two places, so adding an intermediate variable allows
documenting its purpose. The "remote-name" grammer (which is interchangably
used with "path") also seemed to be missing from the grammar, so adding it.

The `domain` variable didn't make it clear that this could include port-numbers
as well, so renaming it makes that more visible.

The remaining uses of "expression()" were quite trivial; probably goes without
saying, but just using string-concatenating for these is more performant as well,
and removing the extra abstraction may make it easier to read;

With the exception of ".", none of the literals used required escaping, which made
the function rather redundant (and the extra abstraction made it harder to read).

NameRegexp does not have capturing groups, so updating the documentation
to reflect that.
To verify if this was an unintentional regression, I looked up the commit
that introduced this regex (31a448a628), and
it looks like it never had capturing groups, so this was just a mistake in
the docs.

This patch:
- makes regexp strings that are constant a const
- moves some variables closer to where they're used
- removes some intermediate vars
- un-wraps some lines; they're lengthy, but probably more readable than having
them wrapped over multiple lines.
- touches-up some docs.

Not all tests have been rewritten to use sub-tests; for those
I enabled t.Parallel() for the parent test only.
