* 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.

* @warn and Sass deprecations are printed as WARN
* @debug is currently logged as INFO (needs the `--verbose` flag). We may adjust this if it gets too chatty.
Fixes#9683
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 = ['.*']
```
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.
Fixes#8945
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)
```
See #8749
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
This commit fixes some issues where modules in /assets share the same name as in node_modules.
This was not intended, and with this commit the node_modules-components should be isolated. If you want to redefine something inside node_modules, use the `defines` option.
Fixes#7948
Updates #7777
Added support to allow SourceMap files to be external to the build.
In addition added more information when the js compilation has an error.
Correctly append sourceMappingURL to output file.
Fix merge conflict.
This change is mostly motivated to get a more stable CI build (we're building the Hugo site there, with Instagram and Twitter shortcodes sometimes failing).
Fixes#7866
This commit also introduces a convention where these common JS config files, including `package.hugo.json`, gets mounted into:
```
assets/_jsconfig
´``
These files mapped to their real filename will be added to the environment when running PostCSS, Babel etc., so you can do `process.env.HUGO_FILE_TAILWIND_CONFIG_JS` to resolve the real filename.
But do note that `assets` is a composite/union filesystem, so if your config file is not meant to be overridden, name them something specific.
This commit also adds adds `workDir/node_modules` to `NODE_PATH` and `HUGO_WORKDIR` to the env when running the JS tools above.
Fixes#7644Fixes#7656Fixes#7675
Added a flag to allow turning on sourcemap in ESBuild. The current support
can only support inline or true as value for sourcemap. This is because
the way ESBuild is invoked it doesn't have a separate output path
to write the mapfile external to the asset pipeline. Add disable for "" and "0".
Add test script and make sure mage check passes.
Fixes#7607
