This new configuration parameter causes paths matching
"<dir>/index.html" to be stored as "<dir>/" remotely. This simplifies
the cloud configuration needed for some use cases, such as CloudFront
distributions with S3 bucket origins. Before this change, users must
configure their S3 buckets as public websites (which is incompatible
with certain authentication / authorization schemes), or users must add
a CloudFormation function to add index.html to the end of incoming
requests. After this change, users can simply use an ordinary CloudFront
distribution (no additional code) with an ordinary S3 bucket origin (and
not an S3 website).
This adds tests to ensure that functionality like matchers is unaffected
by this change. I have also tested that the functionality works as
expected when deploying to a real S3 / CloudFront website.

This fixes a set of bugs (see issue list) and it is also paying some technical debt accumulated over the years. We now build with Staticcheck enabled in the CI build.
The performance should be about the same as before for regular sized Hugo sites, but it should perform and scale much better to larger data sets, as objects that uses lots of memory (e.g. rendered Markdown, big JSON files read into maps with transform.Unmarshal etc.) will now get automatically garbage collected if needed. Performance on partial rebuilds when running the server in fast render mode should be the same, but the change detection should be much more accurate.
A list of the notable new features:
* A new dependency tracker that covers (almost) all of Hugo's API and is used to do fine grained partial rebuilds when running the server.
* A new and simpler tree document store which allows fast lookups and prefix-walking in all dimensions (e.g. language) concurrently.
* You can now configure an upper memory limit allowing for much larger data sets and/or running on lower specced PCs.
We have lifted the "no resources in sub folders" restriction for branch bundles (e.g. sections).
Memory Limit
* Hugos will, by default, set aside a quarter of the total system memory, but you can set this via the OS environment variable HUGO_MEMORYLIMIT (in gigabytes). This is backed by a partitioned LRU cache used throughout Hugo. A cache that gets dynamically resized in low memory situations, allowing Go's Garbage Collector to free the memory.
New Dependency Tracker: Hugo has had a rule based coarse grained approach to server rebuilds that has worked mostly pretty well, but there have been some surprises (e.g. stale content). This is now revamped with a new dependency tracker that can quickly calculate the delta given a changed resource (e.g. a content file, template, JS file etc.). This handles transitive relations, e.g. $page -> js.Build -> JS import, or $page1.Content -> render hook -> site.GetPage -> $page2.Title, or $page1.Content -> shortcode -> partial -> site.RegularPages -> $page2.Content -> shortcode ..., and should also handle changes to aggregated values (e.g. site.Lastmod) effectively.
This covers all of Hugo's API with 2 known exceptions (a list that may not be fully exhaustive):
Changes to files loaded with template func os.ReadFile may not be handled correctly. We recommend loading resources with resources.Get
Changes to Hugo objects (e.g. Page) passed in the template context to lang.Translate may not be detected correctly. We recommend having simple i18n templates without too much data context passed in other than simple types such as strings and numbers.
Note that the cachebuster configuration (when A changes then rebuild B) works well with the above, but we recommend that you revise that configuration, as it in most situations should not be needed. One example where it is still needed is with TailwindCSS and using changes to hugo_stats.json to trigger new CSS rebuilds.
Document Store: Previously, a little simplified, we split the document store (where we store pages and resources) in a tree per language. This worked pretty well, but the structure made some operations harder than they needed to be. We have now restructured it into one Radix tree for all languages. Internally the language is considered to be a dimension of that tree, and the tree can be viewed in all dimensions concurrently. This makes some operations re. language simpler (e.g. finding translations is just a slice range), but the idea is that it should also be relatively inexpensive to add more dimensions if needed (e.g. role).

This allows the AWS credentials to be picked up from the configured
target URL (like blob does) rather than the current behaviour of only
relying on the defaults.
Relying on the defaults here means having to specify credentials twice
(once in the URL for the blob, once in the environment for this code
path) when non-default AWS credentials are in used (e.g. via a profile).
This was broken in the config rewrite in Hugo 0.112.0.
The workaround is to be explicit about setting these flag values (even if just using the defaults), e.g.:
```
hugo deploy --invalidateCDN --maxDeletes 256
```
Fixes#11127
Primary motivation is documentation, but it will also hopefully simplify the code.
Also,
* Lower case the default output format names; this is in line with the custom ones (map keys) and how
it's treated all the places. This avoids doing `stringds.EqualFold` everywhere.
Closes#10896Closes#10620
* Add file context to minifier errors when publishing
* Misc fixes (see issues)
* Allow custom server error template in layouts/server/error.html
To get to this, this commit also cleans up and simplifies the code surrounding errors and files. This also removes the usage of `github.com/pkg/errors`, mostly because of https://github.com/pkg/errors/issues/223 -- but also because most of this is now built-in to Go.

During Hugo deploy when a remote MD5 is invalid (e.g due to multipart eTag) Hugo reads the entire remote file and calculates the MD5 again which can be slow.
This commit updates the file upload so that it will also store an MD5 hash in the cloud provider's attributes. e.g in AWS this looks like x-amz-meta-md5chksum: 26fe392386a8123bf8956a16e08cb841.
The main motivation behind this is simplicity and correctnes, but the new small config library is also faster:
```

BenchmarkDefaultConfigProvider/Custom-16 450756 2651 ns/op 1008 B/op 6 allocs/op
```

So we can use it and output.Format as map key etc.
This commit also fixes the media.Type implementation so it does not need to mutate itself to handle different suffixes for the same MIME type, e.g. jpg vs. jpeg.
This means that there are no Suffix or FullSuffix on media.Type anymore.

Currently, if cache invalidation is enabled when running `hugo deploy --dryRun` with , the deployer does not take the dry run flag into consideration and triggers CloudFront/GoogleCloudCDN cache invalidation if any of those services are configured.
This change will instead print a feedback message if a dry run is in effect and quiet mode is not enabled.
Fixes#7884
