Cover letter [PATCH v4 00/19] Adds reftable library code from https://github.com/hanwen/reftable.
The reftable format is described in Documentation/technical/reftable.txt.
This is a fully reentrant implementation of reading and writing the reftable file format, and should be suitable for embedding in libgit2 too. It does not hook the code up to git to function as a ref storage backend yet.
v4:
* fixes by Carlo Belón.
* remove RFC from LICENSE commit.
