Make entry.type consistent arcoss various APIs

[Gozala]

Following APIs seem to return different thing for entry.type:

• ipfs.files.ls-> type: 1 (While docs say it's either 'file' | 'dir' https://github.com/ipfs/js-ipfs/blob/master/docs/core-api/FILES.md#ipfsfileslspath-options)
• ipfs.files.stat -> type: 'directory'
• ipfs.ls -> type: 'dir' (Docs don't specify but given others been document as 'directory' one would assume the same)

This can be very confusing when working with all these APIs as just like ipfs-webui does.

I would like to propose normalizing to a consistent variants for type.

Yes please, this has been on the list for ages. All type fields should be one of the UnixFS data types, my preference is for lower case, kebab-case strings, though using the enum value from the UnixFS spec would also be acceptable and strings could be a UI concern, but beware that go-IPFS uses different numbers depending on context.

Also see ipfs/kubo#7553 for another stat command that's being added.

Closing as this issue is very stale.
