all: Rework page store, add a dynacache, improve partial rebuilds, and some general spring cleaning
There are some breaking changes in this commit, see #11455.

Closes #11455
Closes #11549

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).

241b21b0fd Create a struct with all of Hugo's config options
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.

90da7664bf Add page fragments support to Related
The main topic of this commit is that you can now index fragments (content heading identifiers) when calling `.Related`.

You can do this by:

* Configure one or more indices with type `fragments`
* The name of those index configurations maps to an (optional) front matter slice with fragment references. This allows you to link
page<->fragment and page<->page.
* This also will index all the fragments (heading identifiers) of the pages.

It's also possible to use type `fragments` indices in shortcode, e.g.:

```
{{ $related := site.RegularPages.Related .Page }}
```

But, and this is important, you need to include the shortcode using the `{{<` delimiter. Not doing so will create infinite loops and timeouts.

This commit also:

* Adds two new methods to Page: Fragments (can also be used to build ToC) and HeadingsFiltered (this is only used in Related Content with
index type `fragments` and `enableFilter` set to true.
* Consolidates all `.Related*` methods into one, which takes either a `Page` or an options map as its only argument.
* Add `context.Context` to all of the content related Page API. Turns out it wasn't strictly needed for this particular feature, but it will
soon become usefil, e.g. in #9339.

Pass minification errors to the user
Previously, *minifyTransformation.Transform suppressed the
error returned by t.m.Minify. This meant that when minification
returned an error, the error would not reach the user. Instead,
minification would silently fail. For example, if a JavaScript
file included a call to the Date constructor with:

new Date(2020, 04, 02)

The package that the minification library uses to parse JS files,
github.com/tdewolff/parse would return an error, since "04" would
be parsed as a legacy octal. However, the JS file would remain
un-minified with no error.

Fixing this is not as simple as replacing "_" with an "err" in
*minifyTransformation.Transform, however (though this is
necessary). If we only returned this error from Transform,
then hugolib.TestResourceMinifyDisabled would fail. Instead of
being a no-op, as TestResourceMinifyDisabled expects, using the
"minify" template function with a "disableXML=true" config
setting instead returns the error, "minifier does not exist for
mimetype."

The "minifier does not exist" error is returned because of the
way minifiers.New works. If the user's config disables
minification for a particular MIME type, minifiers.New does
not add it to the resulting Client's *minify.M. However, this
also means that when the "minify" template function is executed,
 a *resourceAdapter's transformations still add a minification.
When it comes time to call the minify.Minifier for a specific
MIME type via *M.MinifyMimetype, the github.com/tdewolff/minify
library throws the "does not exist" error for the missing MIME
type.

The solution was to change minifiers.New so, instead of skipping
a minifier for each disabled MIME type, it adds  a NoOpMinifier,
which simply copies the source to the destination without
minification. This means that when the "minify" template
function is used for a particular resource, and that resource's
MIME type has minification disabled, minification is genuinely
skipped, and does not result in an error.

In order to add this, I've fixed a possibly unwanted interaction
between minifiers.TestConfigureMinify and
hugolib.TestResourceMinifyDisabled. The latter disables
minification and expects minification to be a no-op. The former
disables minification and expects it to result in an error. The
only reason hugolib.TestResourceMinifyDisabled passes in the
original code is that the "does not exist" error is suppressed.
However, we shouldn't suppress minification errors, since they
can leave users perplexed. I've changed the test assertion in
minifiers.TestConfigureMinify to expect no errors and a no-op
if minification is disabled for a particular MIME type.

Image resource refactor
This commit pulls most of the image related logic into its own package, to make it easier to reason about and extend.

This is also a rewrite of the transformation logic used in Hugo Pipes, mostly to allow constructs like the one below:

    {{ ($myimg | fingerprint ).Width }}
