Note that we only use this for change detection.
The previous implementation invoked `MD5FromReaderFast` that created a MD5 has from 8 64 bytes chunks in the file, which is obviously very fast. The new implementation creates the hash from the entire file and ... seems to be even more effective:
```
name old time/op new time/op delta
HashImage-10 9.45µs ±21% 10.89µs ± 1% ~ (p=0.343 n=4+4)
name old alloc/op new alloc/op delta
HashImage-10 144B ± 0% 8B ± 0% -94.44% (p=0.029 n=4+4)
name old allocs/op new allocs/op delta
HashImage-10 4.00 ± 0% 1.00 ± 0% -75.00% (p=0.029 n=4+4)
```
This was partly broken in Hugo 0.123.0.
We have two internal config options that gets set from the CLI:
* Running; a web server is running
* Watching; either set via `hugo -w` or `hugo server --watch=false`
Part of the change detection code wrongly used the `Running` as a flag when `Watching` would be the correct.
Fixes#12296
The main use case for this is to resolve links and resources (e.g. images) relative to the included `Page`.
A typical `include` would similar to this:
```handlebars
{{ with site.GetPage (.Get 0) }}
{{ .RenderShortcodes }}
{{ end }}
```
And when used in a Markdown file:
```markdown
{{% include "/posts/p1" %}}
```
Any render hook triggered while rendering `/posts/p1` will get `/posts/p1` when calling `.PageInner`.
Note that
* This is only relevant for shortcodes included with `{{%` that calls `.RenderShortcodes`.
* `.PageInner` is available in all render hooks that, before this commit, received `.Page`.
* `.PageInner` will fall back to the value of `.Page` if not relevant and will always have a value.

Define global inclusion/exclusion in site configuration, and override
via front matter. For example, to exclude a page from the sitemap:
[sitemap]
disable = true # default is false

Changes:
- Remove trailing comma from list of keywords.
- Improve keywords precedence:
1. Use "keywords" term page titles.
2. Use "keywords" from front matter if "keywords" is not a taxonomy.
3. Use "tags" term page titles.
4. Use term page titles from all taxonomies.
- Enable schema for all page kinds, previously limited to kind = page.
- Remove trailing slashes from void elements.
- Improve readability.

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).

The page images selection order as follows:
1. Page's images parameter, image resources are supported.
2. Page's image resources that naming in *feature*, *cover* or *thumbnail* pattern.
3. If no page images specified, then the first one of site's images will be used as the fallback, supports site resources.
