* feat: serveRawBlock implements ?format=block * feat: serveCar implements ?format=car * feat(gw): ?format= or Accept HTTP header - extracted file-like content type responses to separate .go files - Accept HTTP header with support for application/vnd.ipld.* types * fix: use .bin for raw block content-disposition .raw may be handled by something, depending on OS, and .bin seems to be universally "binary file" across all systems: https://en.wikipedia.org/wiki/List_of_filename_extensions_(A%E2%80%93E) * refactor: gateway_handler_unixfs.go - Moved UnixFS response handling to gateway_handler_unixfs*.go files. - Removed support for X-Ipfs-Gateway-Prefix (Closes #7702) * refactor: prefix cleanup and readable paths - removed dead code after X-Ipfs-Gateway-Prefix is gone (https://github.com/ipfs/go-ipfs/issues/7702) - escaped special characters in content paths returned with http.Error making them both safer and easier to reason about (e.g. when invisible whitespace Unicode is used)
