Without this, all entries will have nlink==0, which confuses a bunch
of tools. Most dramatically, systemd-nspawn enters a busy loop in its
lock utility function.

To test it, set up an S3 bucket (in an AWS region that is not US
Standard, for read-after-write consistency), run `ipfs init`, then
edit `~/.ipfs/config` to say
"Datastore": {
"Type": "s3",
"Region": "us-west-1",
"Bucket": "mahbukkit",
"ACL": "private"
},
with the right values. Set `AWS_ACCESS_KEY_ID` and
`AWS_SECRET_ACCESS_KEY` in the environment and you should be able to
run `ipfs add` and `ipfs cat` and see the bucket be populated.
No automated tests exist, unfortunately. S3 is thorny to simulate.

Earlier, it also checked checked the leveldb directory. That part
added no crash safety to the application, and just hardcoded
assumptions about the datastore.
If anything, this should rely on the absolute last item created by
fsrepo.Init, and there should be fsync guarantees about ordering.

reintroduce indirect pinning, add enumerateChildren dag method
License: MIT
Signed-off-by: Jeromy <jeromyj@gmail.com>
This commit improves (fixes) the FetchGraph call for recursively
fetching every descendant node of a given merkledag node. This operation
should be the simplest way of ensuring that you have replicated a dag
locally.
This commit also implements a method in the merkledag package called
EnumerateChildren, this method is used to get a set of the keys of every
descendant node of the given node. All keys found are noted in the
passed in KeySet, which may in the future be implemented on disk to
avoid excessive memory consumption.

The addition of a locking interface to the blockstore allows us to
perform atomic operations on the underlying datastore without having to
worry about different operations happening in the background, such as
garbage collection.

Note from jbenet: Maybe we should remove the old protocol/muxer
and see what breaks. It shouldn't be used by anything now.

There was doublewrapping with an unneeded msgio. given that we
use a stream muxer now, msgio is only needed by secureConn -- to
signal the boundaries of an encrypted / mac-ed ciphertext.
Side note: i think including the varint length in the clear is
actually a bad idea that can be exploited by an attacker. it should
be encrypted, too. (TODO)

WARNING: No migration performed! That needs to come in a separate
commit, perhaps amended into this one.
This is the minimal rewrite, only changing the storage from
JSON(+extra keys) in Datastore to IPFS objects. All of the pinning
state is still loaded in memory, and written from scratch on Flush. To
do more would require API changes, e.g. adding error returns.
Set/Multiset is not cleanly separated into a library, yet, as it's API
is expected to change radically.
