Stuff in merge-all and not in merge minus minor changes:
Important note about "merge-all" branch
=======================================
Goal of the rather experimental "merge-all" branch is to merge all the stuff:
- changesets from "merge" branch
- features that DO IMPACT compatibility with original attic
- etc.
THERE IS NO GUARANTEE THAT IT IS COMPATIBLE WITH ORIGINAL ATTIC OR PREVIOUS
"merge-all" CODE nor THAT YOU CAN SWITCH BACK AND FORTH BETWEEN ORIGINAL CODE
OR PREVIOUS "merge-all" CODE AND THIS CODE WITHIN THE SAME REPOSITORY WITHOUT
ENCOUNTERING SEVERE ISSUES.
Please also see the LICENSE for more informations.

source: more flexible type 0x03 header format, allowing to give hash algo,
compression algo and level, encryption algo, key type.
IV is stored in full length, length of stored IV/MAC/hash is flexible.
Indexing key size (key = id_hash()) is flexible and configurable per repo.
source: less hardcoding, numeric offsets / lengths
source: flexible hashing, compression, encryption, key dispatching
