[RFC v2][PATCH 0/3] Introduce base-apt

[Alexander Smirnov <asmirnov@ilbers.de>]

Hello everybody,

first of all, to avoid unnecessary effort I've diced to split build
reproducibility feature into two parts:
 - base-apt creation
 - switch Isar to base-apt

So this series introduces base-apt only.

If set ISAR_BUILD_REP = "1", Isar creates base-apt repository that contains
debs for all possible build targets within current tree.

Special notes:
 - To derive dependencies, I've added DEBIAN_DEPENDS variable which duplicates
   'debian/control' content. IMHO this is the best compromise for now.
 - I use multistrap to fetch debs, I haven't found for now any other tool that
   could fetch debs from multiple sources. The issue is that multistrap doesn't
   understand 'debian/control' format, so perl parsing is used.

Alexander Smirnov (3):
  dpkg-base: Make DEBIAN_DEPENDS global
  build-rep: Add helper class
  base-apt: Introduce fetching upstream apt
