Eclipse JGit: Java implementation of Git 5.6.0

5.6.0

Description

Implement FileReftableDatabase

Reftable is a binary, block-based storage format for the ref-database. It provides several advantages over the traditional packed + loose refs storage

Storage format:
- O(1) write performance, even for deletions and transactions.
- atomic updates to the ref database.
- O(log N) lookup and prefix scans
- free from restrictions imposed by the file system: it is case-sensitive even on case-insensitive file systems, and has no inherent limitations for directory/file conflicts
prefix compression reduces space usage for repetitive ref names, such as gerrit's refs/changes/xx/xxxxx format.
FileReftableDatabase is based on FileReftableStack, which does compactions inline. This is simple, and has good median performance, but every so often it will rewrite the entire ref database.
Add FileRepository#convertToReftable so existing testdata can be reused.
