[PATCH v3 0/4] Basic binary cache implementation

[Alexander Smirnov <asmirnov@ilbers.de>]

Hello everybody,

this series introduces basic binary caching for Isar.

There is a new layer: meta-isar-bin which is intended to be the binary
cache. All the packages that are built in Isar are stored in this
cache using reprepro.

Having the separate layer makes possible to manage this cache separately
from the Isar build tree. So once you have built your packages, you could
re-use this cache for further builds.

Also this cache repo is now used to generate image filesystem via
multistrap.

Changes since v2:
 - Droped anonymous functions
 - Added number of attempts to access apt cache before fail

Changes since v1:
 - Total refactoring
 - Split huge patches into small pieces
 - Avoid races

With best regards,
Alex
