799c654b0d resource: Preserve color palette for PNG images 
This commit will force a reprocessing of PNG images with new names, so it is adviced to run a `hugo --gc` to remove stale files.

58382e9572 resource: Fix multi-threaded image processing issue 
When doing something like this with the same image from a partial used in, say, both the home page and the single page:

```bash
{{ with $img }}
{{ $big := .Fill "1024x512 top" }}
{{ $small := $big.Resize "512x" }}
{{ end }}
```

There would be timing issues making Hugo in some cases try to process the same image with the same instructions in parallel.

You would experience errors of type:

```bash
png: invalid format: not enough pixel data
```

This commit works around that by adding a mutex per image. This should also improve the performance, sligthly, as it avoids duplicate work.

The current workaround before this fix is to always operate on the original:

```bash
{{ with $img }}
{{ $big := .Fill "1024x512 top" }}
{{ $small := .Fill "512x256 top" }}
{{ end }}
```

resource: Add smart cropping 
This commit `smart` as a new and default anchor in `Fill`.

So:

```html
{{ $image.Fill "200x200" }}
```

Is, with default configuration, the same as:

```html
{{ $image.Fill "200x200" "smart" }}
```

You can change this default in your `config.toml`:

```toml
[imaging]
[imaging]
resampleFilter = "box"

quality = 68

anchor = "Smart"
```

resource: Start Resources :counter first time they're used 
This is less surprising and more flexible than the original implementation.

Given:

```toml
[[resources]]
  src = "documents/photo_specs.pdf"
  title = "Photo Specifications"
[[resources]]
  src = "**.pdf"
  name = "pdf-file-:counter"
```

Every `pdf` in the bundle will have an unique counter, but the `photo_specs.pdf` is still allowed to have its specific `title`.

If you change the above example to:

```toml
[[resources]]
  src = "documents/*specs.pdf"
  title = "Photo Specifications #:conter"
[[resources]]
  src = "**.pdf"
  name = "pdf-file-:counter"
```

We are talking about two different groups of documents, each with its own counters starting at 1.

5a0819b9b5 Merge matching resources params maps 
This allows setting default params values in the more general resource matchers. I also allows override with more specific values if needed.

```toml
[[resources]]
src = "documents/photo_specs.pdf"
title = "Photo Specifications"
[resources.params]
ref = 90564687
icon = "photo"
[[resources]]
src = "documents/guide.pdf"
title = "Instruction Guide"
[resources.params]
ref = 90564568
[[resources]]
src = "documents/checklist.pdf"
title = "Document Checklist"
[resources.params]
ref = 90564572
[[resources]]
src = "documents/payment.docx"
title = "Proof of Payment"
[[resources]]
src = "documents/*.pdf"
title = "PDF file"
[resources.params]
icon = "pdf"
[[resources]]
src = "documents/*.docx"
title = "Word document"
[resources.params]
icon = "word"

```

In the above `TOML` example, `photo_specs.pdf` will get the `photo` icon, the other pdf files will get the default `pdf` icon.

Note that in the example above, the order matters: It will take the first value for a given params key, title or name that it finds.

resource: Add Match and GetMatch 
These methods takes a glob pattern as argument:

* by default matching from the bundle root
* matching is case insensitive and the separator is Unix style slashes: "/"
* the bundle root does (by default) not start with a leading slash
* if you renames the `Name` for the rsource in front matter (`src=...`), then that is the value used in `Match`.
* double asterisk matches beyond directory borders, so "**.jpg" will match any JPEG image in the bundle

See https://github.com/gobwas/glob

This commit also deprecates `ByPrefix` and `GetByPrefix`.

This should also be more effective, given a fair amount of reuse of the glob patterns:

```bash
BenchmarkResourcesByPrefix-4         300000          4284 ns/op        1130 B/op           7 allocs/op
BenchmarkResourcesMatch-4            300000          5220 ns/op         505 B/op           3 allocs/op
```

resource: Add front matter metadata to Resource 
This commit expands the Resource interface with 3 new methods:

* Name
* Title
* Params

All of these can be set in the Page front matter. `Name` will get its default value from the base filename, and is the value used in the ByPrefix and GetByPrefix lookup methods.

✨ Implement Page bundling and image handling 
This commit is not the smallest in Hugo's history.

Some hightlights include:

* Page bundles (for complete articles, keeping images and content together etc.).
* Bundled images can be processed in as many versions/sizes as you need with the three methods `Resize`, `Fill` and `Fit`.
* Processed images are cached inside `resources/_gen/images` (default) in your project.
* Symbolic links (both files and dirs) are now allowed anywhere inside /content
* A new table based build summary
* The "Total in nn ms" now reports the total including the handling of the files inside /static. So if it now reports more than you're used to, it is just **more real** and probably faster than before (see below).

A site building  benchmark run compared to `v0.31.1` shows that this should be slightly faster and use less memory:
