Revert "Use prefix iterators for Get/Has()"

[hsanjuan]

Upon testing this on high concurrency scenario, it would seem that this makes reading very very slow in comparison to the previous implementation (ie. 50 vs 3000 ipfs block-reads per second).

For this reason we must revert.

Hmmm i think things may slow down too even with this reverted :cry:

Cutting a Release (and modifying non-markdown files)

This PR is modifying both version.json and non-markdown files. The Release Checker is not able to analyse files that are not checked in to master. This might cause the above analysis to be inaccurate. Please consider performing all the code changes in a separate PR before cutting the release.

Automatically created GitHub Release

A draft GitHub Release has been created. It is going to be published when this PR is merged. You can modify its' body to include any release notes you wish to include with the release.

This is merged because upstream pebble uses bloom filters now, so we don't need to complicate things here.
