This applies cherry-picked patches from: ipfs/js-ipfs#1989 ipfs/js-ipfs#1950 and solves stream issues on page refresh. Content-type sniffing is now done over a meaningful amount of bytes instead of arbitrary number.

As this PR was not merged and I had more improvements built on top of it, I've just pushed those additional improvements here and updated description to reflect what changed. Note: We should review & merge this before we add support for Question: If I wanted to add interop (go-vs-js) tests for relevant HTTP headers, which repo should I use? |

This change simplifies code responsible for streaming response and makes the streaming actually work by telling the payload compression stream to flush its content on every read(). (previous version was buffering entire thing in Hapi's compressor memory) We also do content-type detection based on the beginning of the stream by peeking at first `fileType.minimumBytes` bytes.

- Switched from deprecated `hapi` and `joi` to `@hapi/hapi` and `@hapi/joi`
- Added support for Conditional Requests (RFC7232)
- Returning `304 Not Modified` if `If-None-Match` is a CID matching `Etag`
- Added `Last-Modified` to `/ipfs/` responses (improves client-side caching)
- Always returning `304 Not Modified`
when `If-Modified-Since` is present for immutable `/ipfs/`
- Added support for Byte Range requests (RFC7233, Section-2.1)
- Added support for `?filename=` parameter (improves downloads of raw cids)

> Part of an effort to run embedded js-ipfs in Brave 🦁 ipfs/ipfs-companion#716 > Fixes #1918 This PR will add support for `/ipns/` paths at HTTP Gateway. Smoke test: [/ipns/tr.wikipedia-on-ipfs.org](http://127.0.0.1:9090/ipns/tr.wikipedia-on-ipfs.org/wiki/Anasayfa.html) (IPNS+DNSLink+HAMT-sharded website) This PR depends on the following merged PRs: - Gateway Improvements from #1989 (after merging #1989 I will rebase this PR, which will remove first two commits) - PeerID eg. `/ipns/<PeerId-as-multihash-b58>` - requires #2002 to land first - `/ipns/<libp2p-key-in-cidv1>` - requires multiformats/js-multicodec#45 - DNSLink eg. `/ipns/<fqdn>/path/file` like `/ipns/docs.ipfs.io/assets/logo.svg` - requires #2002 to land first - HAMT shard support eg. `/ipns/tr.wikipedia-on-ipfs.org/wiki/Anasayfa.html` (`wiki` is a sharded directory) - requires ipfs/js-ipfs-http-response#22 and ipfs-inactive/js-ipfs-mfs#48 to land first - Tests for `/ipns/` License: MIT Signed-off-by: Marcin Rataj <[email protected]>
