[PATCH v8 0/7] Fix 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 v7: Complete rework :)

After a hard discussion things turned out to be cleaner and less error
prone. Thank you, Claudius!

* No keys added to host at all
* Keys needed for bootstrapping go to a separated keyring in the
  workdir
* Third party apt keys are added to
  /etc/apt/trusted.gpg.d/third_party.gpg only in the generated rootfs

* The following variables are renamed/created:

  Old name                New name
  -                       DISTRO_BOOTSTRAP_KEYRING
  DISTRO_APT_KEYS         DISTRO_BOOTSTRAP_KEYS
  -                       DISTRO_BOOTSTRAP_KEYFILES
  ISARKEYRING             THIRD_PARTY_APT_KEYRING
  -                       THIRD_PARTY_APT_KEYS
  APTKEYFILES             THIRD_PARTY_APT_KEYFILES

Tested building without error:
  qemuarm64-stretch
  qemuarm64-stretch with 3rd party docker repo
  raspbian-jessie

Not working yet:
  qemuarm64-stretch with BASE_REPO_KEY and do_cache_base_repo

| gpgme gave error GPGME:54:  Unusable secret key

I have created a keypair inside the build container and exported the
public key to a file "blabla.key". Then I set

BASE_REPO_KEY = "file:///build/blabla.key"

Any idea?

  Revert "isar-bootstrap: Allow to set local keys in DISTRO_APT_KEYS"
  Remove duplicate code from apt-keyring generation
  Fix fetched key location in apt-keyring generator
  Use apt-key to generate keyrings
  If we use a custom keyring debootstrap may fall to https
