In page.NewOutputFormat, we take an output.Format f and use it to
create a page.OutputFormat. If the format is canonical, we assign
the final OutputFormat's Rel to "canonical" rather than using
f.Rel. However, this leads to unexpected behavior for custom
output formats, where a user can define a "rel" for a format
via the config file.
For example, the standard for "humans.txt" files requires using
rel="author" in HTML "link" elements. Meanwhile, humans.txt is
usually the only format used for its content. As a result, for
Hugo configurations that define a humans.txt custom output format,
Hugo will render "link" elements to content in this format with
rel="canonical," rather than "author" as required by the standard.
This commit changes page.NewOutputFormat to check whether a given
format is user defined and, if so, skips assigning Rel to
"canonical," even if isCanonical is true.
Fixes#8030
This is a security hardening measure; don't trust the URL extension or any `Content-Type`/`Content-Disposition` header on its own, always look at the file content using Go's `http.DetectContentType`.
This commit also adds ttf and otf media type definitions to Hugo.

In Hugo 0.89 we added remote support to `resources.Get`.
In hindsight that was not a great idea, as a poll from many Hugo users showed. See Issue #9285 for more details.
After this commit `resources.Get` only supports local resource lookups. If you want to support both, you need to use a construct similar to:
Also improve some option case handling.
```
{{ resource := "" }}
{{ if (urls.Parse $url).IsAbs }}
{{ $resource = resources.GetRemote $url }}
{{ else }}
{{ $resource = resources.Get $url }}
{{ end }}
```

This ommmit contains some security hardening measures for the Hugo build runtime.
There are some rarely used features in Hugo that would be good to have disabled by default. One example would be the "external helpers".
For `asciidoctor` and some others we use Go's `os/exec` package to start a new process.
These are a predefined set of binary names, all loaded from `PATH` and with a predefined set of arguments. Still, if you don't use `asciidoctor` in your project, you might as well have it turned off.
You can configure your own in the new `security` configuration section, but the defaults are configured to create a minimal amount of site breakage. And if that do happen, you will get clear instructions in the loa about what to do.
The default configuration is listed below. Note that almost all of these options are regular expression _whitelists_ (a string or a slice); the value `none` will block all.
```toml
[security]
enableInlineShortcodes = false
[security.exec]
allow = ['^dart-sass-embedded$', '^go$', '^npx$', '^postcss$']
osEnv = ['(?i)^(PATH|PATHEXT|APPDATA|TMP|TEMP|TERM)$']
[security.funcs]
getenv = ['^HUGO_']
[security.http]
methods = ['(?i)GET|POST']
urls = ['.*']
```
In Hugo 0.90.0 we introduced remote support in `resources.Get`.
But with remote resources comes with a higher chance of failing a build (network issues, remote server down etc.).
Before this commit we always failed the build on any unexpected error.
This commit allows the user to check for any error (and potentially fall back to a default local resource):
```htmlbars
{{ $result := resources.Get "https://gohugo.io/img/hugo-logo.png" }}
{{ with $result }}
{{ if .Err }}
{{/* log the error, insert a default image etc. *}}
{{ else }}
<img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
{{ end }}
{{ end }}
```
Note that the default behaviour is still to fail the build, but we will delay that error until you start using the `Resource`.
Fixes#9529
As documented in commit 30eea3915b,
some filenames have changed due to cache busting of PNG and Webp images.
This resolves recent TestImageOperationsGolden failure on arm64, ppc64le
and s390x.
See #6387 and #8729
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.

This is in line with how both Node and ESBuild's native import resolver does it.
The ambiguous situations above were discovered trying to build AlpineJS v3.
Note that the above was never an issue if you used `./foo.js` and similar to import the component.

This commit started out investigating a `concurrent map read write` issue, ending by replacing the map with a struct.
This is easier to reason about, and it's more effective:
```
name old time/op new time/op delta
SiteNew/Regular_Deep_content_tree-16 71.5ms ± 3% 69.4ms ± 5% ~ (p=0.200 n=4+4)
name old alloc/op new alloc/op delta
SiteNew/Regular_Deep_content_tree-16 29.7MB ± 0% 27.9MB ± 0% -5.82% (p=0.029 n=4+4)
name old allocs/op new allocs/op delta
SiteNew/Regular_Deep_content_tree-16 313k ± 0% 303k ± 0% -3.35% (p=0.029 n=4+4)

This commit adds support for using the `cascade` keyword in your configuration file(s), e.g. `config.toml`.
Note that
* Every feature of `cascade` is available, e.g. `_target` to target specific page sets.
* Pages, e.g. the home page, can overwrite the cascade defined in config.
Fixes#8741
Keep this as a separate commit as this isn't because the files have changed. The filenames have changed due to cache busting of PNG and Webp images.
See #8729
The main motivation behind this is simplicity and correctnes, but the new small config library is also faster:
```
BenchmarkDefaultConfigProvider/Viper-16 252418 4546 ns/op 2720 B/op 30 allocs/op
BenchmarkDefaultConfigProvider/Custom-16 450756 2651 ns/op 1008 B/op 6 allocs/op
```

Updates #8591Closes#6680Closes#5192
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.

The root cause of issue #8079 was a non-breaking space (U+0160).
`unicode.IsPrint` only allows the ASCII space (U+0020). Be more lenient
by using `unicode.IsGraphic` instead.
