These changes are needed to prepare for the Directory page UI improvements
implemented in https://github.com/ipfs/dir-index-html/issues/37.
- update dir-index-html type structs
- emit gateway URL for root links
- emit CID of each directoryItem
- emit size of directory
- emit breadcrumbs
While the content of raw files retrieved via the gateway should never
change, the look and feel of the directory index can and will change
between versions of go-ipfs.
Incorporate the hash of assets/bindata.go into the ETag when appropriate
fixes https://github.com/ipfs/go-ipfs/pull/4233#issuecomment-631454543
Basically, there's a trade-off here:
1. We can support directory listings while supporting 404 pages (this PR).
2. If a 404 page is present, directory listings don't work.
Given that option 1 is more flexible and users shouldn't be _too_ confused if
they land on a directory with no index.html page, I've gone with that option.
Files already have an explicit Content-Type set. Be sure to do this for
directory listings as well to avoid a fallback to autodetection in
net/http. That fallback fails when a ResponseWriter is installed that
performs compression.
In the same way that an `index.html` file is rendered, if one is present, when the
requested path is a directory, now an `ipfs-404.html` file is rendered if
the requested file is not present within the specified IPFS object.
`ipfs-404.html` files are looked for in the directory of the requested path and each
parent until one is found, falling back on the well-known 404 error message.

When request is sent to http://localhost:8080/ipfs/$cid response has
HTTP 301 status code and "Location" header with redirect destination at
$cid.ipfs.localhost:8080
Redirect is followed by browsersi, but not by commandline tools.
Status 301 is ignored by curl in default mode: it will print response
and won't follow redirect, user needs to add -L for that.
To fix curl, we return correct payload in body of HTTP 301 response,
but set Clear-Site-Data header to ensure Origin sandbox can't be abused.
This requires a surgical workaround:
If Location header is present in ResponseWriter's Header map,
we ensure http.ServeContent() returns HTTP 301

Instead of adding a new fake header (that could be spoofed by the client...),
just read the original request URI from the request object.
This also removes support for suborigins. They have never been implemented in
browsers and it looks like efforts have stalled. We can add support back if we
need it but, well, maintaining support was going to be more trouble than it was
worth.

1. Require files to have known sizes. We can add support for unknown sizes
_later_ but we can't use ServeContent for those files.
2. Replace the `sizeReadSeeker` with a `lazySeeker`. This one makes no
assumptions about how it's used so we're less likely to run into weird bugs.
1. Fix handling of PUT. The simple implementation was the correct
implementation, I have no idea what was going on here.
2. Use MFS everywhere to reduce code duplication and add support for sharded
directories.
3. _Correctly_ block IPNS.
4. Remove the dependency on `core.IpfsNode`.
5. Remove support for putting empty directories with a well-known CID. It was
useless as directories are automatically created.
1. They don't _have_ to be mutually exclusive.
2. local, mode, etc is _really_ confusing.
