      unixfs: add a directory interface · 842c17b9
      Lucas Molas authored 
      Add a UnixFS `Directory` that hides implementation details and helps to
distinguish *what* is a UnixFS directory.

Replace the `unixfs.io.Directory` structure that contained the HAMT and basic
directory implementations (through inner pointers) with an interface containing
the same methods. Implement those methods in two clearly distinct structures for
each implementation (`BasicDirectory` and `HAMTDirectory`) avoiding pointer
logic and clearly differentiating which implementation does what.

The potential basic to HAMT transition was being hidden behind the `AddChild`
call at the UnixFS layer (changing one implementation pointer  with the other
one), it is now being explicitly done at the MFS layer.

Rename the `dirbuilder.go` file to `directory.go` and change the `Directory` MFS
attribute `dirbuilder` to `unixfsDir` to be consistent.

      unixfs: integrate `pb.Data` into `FSNode` · 3c982f0b
      Lucas Molas authored 
      To avoid duplicating fields and making the code easier to follow.

Remove all of `FSNode` previous fields in favor on a single `pb.Data` structure
that is not exported. Accessor methods are added only for the necessary internal
fields. This takes up more memory, `pb.Data` is always created inside `FSNode`
and it stays there instead of just being created and destroyed during the
(un)marshal operations.

The removed fields `Data`, `blocksizes` and `Type` had a direct counterpart in
the embedded `pb.Data` structure, in contrast (only) the `subtotal` field
doesn't have one, it was used as a temporary accumulator to track the
`Filesize`, which is now being kept updated on every modification (to ensure the
entire `FSNode` is always at a valid state), so `subtotal` could just be removed
without the addition of any other field (this temporary accumulator  was
obscuring how `Filesize` was computed).

To keep `Filesize` up to date a method was added (`UpdateFilesize()`) to adjust
its value in the two places where the file size could be modified, when changing
its data (in `SetData()`, accessor method added) and when adding or removing
child nodes (in `AddBlockSize()` and `RemoveBlockSize()`).

A constructor method was added (`NewFSNode()`) to initialize the required
fields, like `Type` which is explicitly set, this deprecates the previous
methodology of just calling `new(FSNode)` and relying in the default value of
`pb.Data_DataType` (`Data_Raw`) to avoid an explicit assignment. Also,
`Filesize` is initialized to avoid being left with a `nil` value before
marshaling empty nodes, which would result in a different hash from previous
versions, to be backwards compatible. Previous versions of `GetBytes()` always
set the `Filesize` value, even though it is reflected as an `optional` field in
the `.proto` file (this may be an inaccurate field rule).

Without the duplicated fields the functions `GetBytes()` and `FSNodeFromBytes()`
are now reduced to simple `Marshal()` and `Unmarshal()` operations respectively.

      dag: deduplicate AddNodeLinkClean into AddNodeLink · 165433d2
      Lucas Molas authored 
      `AddNodeLink` used to cache the linked node whereas `AddNodeLinkClean`
did not, however, at some point the former was changed to do the same
thing as the latter (i.e., not cache the linked node). That is, they now
do the same thing so there's no reason to have both.

The name `AddNodeLink` is preserved, even though it used to imply the
cache functionality contrasting with the `Clean` suffix of
`AddNodeLinkClean`, with this function removed the cache connotation
doesn't hold anymore.
