[PATCH v3 0/6] Fixes usage of additional apt keys and repos

["Andreas J. Reichel" <andreas.reichel.ext@siemens.com>]

From: Andreas Reichel <andreas.reichel.ext@siemens.com>

Diff to v2:
	* split patches in a clean way:
	* only install https-support and ca-certificates if
	  we have provided a custom apt-key
	  (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=891009)
	  - use the existing override mechanism for this
	* first improve existing isar code before adding my own
	* don't include "tmp/" inside of $kfn

What this series does:

Enable the user to really ADD bootstrap repos and keys without
replacing existing ones.

The existing keyring is not replaced but keys are added to
/ect/apt/trusted.gpg.d/isar.gpg instead, where debootstrap and any apt
call can find it.

Furthermore, the code to add keys is simplified by removing duplicate
code and not manually parsing URIs and guessing about download locations
as well as not manually handling gpg and giving apt config overrides.

It is much simpler by using `apt-key` and default apt keyring paths.

Furthermore, apt-get must not use a given single source list which was
used from debootstrapping. Otherwise, additional packages are always
unauthenticated, which is a quite misleading error. Instead, apt-get
should use all source lists available in the built root.

  Revert "isar-bootstrap: Allow to set local keys in DISTRO_APT_KEYS"
  Remove duplicate code from apt-keyring generation
  Fix key filename in apt-keyring generator
  Use apt-key to generate apt-keyring
  Use all source lists in target root apt
  If we use a custom keyring debootstrap may fall to https
