Ipns Consistency

[whyrusleeping]

This PR changes the DHT so that it stores records instead of simple values. This allows us to add a layer of security onto the DHT, and also allows us to validate values that are stored in it.

Currently, only two value types are allows to be stored in the DHT:

• Public Keys
  • Public keys are verified by checking their hash against the key.
  • relevant code
• Ipns Records
  • Ipns records are verified by unmarshalling them, checking their validity type, and then performing the proper validity checks from there
  • relevant code

Other types of Ipns Validity functions should be discussed, as only one is implemented. More complex checks may require a change in how the validity functions are called (maybe add new parameters, etc).

Great PR, as always. A few codebase-friendliness comments up there, but all this LGTM!

@jbenet am i good to merge?

[jbenet]

@whyrusleeping depends, did the commands merge change anything here? we've officially deprecated cmd/ipfs until we migrate cmd/ipfs2 -> cmd/ipfs. Seems like no, but just verifying...

[whyrusleeping]

If you merged over the ipfs name code then no, nothing should have changed.

[jbenet]

merged over the ipfs name code

??

[whyrusleeping]

I mean, if you've ported over the code for ipfs name publish and ipfs name resolve from the original commands set, everything should work great

[btc]

those have been ported

[jbenet]

I'm going to rebase this on top of new master first.
