meta-mortsgna: (more than) yet another distro layer

The target of this layer is to build images with the best out-of-the-box experience and to support developers with helpers for common tasks.
It has its origin Ångström distribution - check https://github.com/Angstrom-distribution/meta-angstrom.

Additional global variable for local.conf:

• MORTSGNA_ARMV7_TUNE:

  If this variable is set to “1”, all armv7a / cortex variants are build as
  armv7a.

  + Reduce build time/disk-space required when building for multiple machines

  - Build optimization (e.g vfp/NEON) is not the best your machine can get

  Rules of thumb:

  • If you build images for multiple armv7 machines and don’t need to tickle
    the last quarter of your machine’s performance:
    Set MORTSGNA_ARMV7_TUNE=”1”
  • If you are looking for best optimization for your machine and/or you have
    a fast build host with lots of disk-space: don’t!
    see mortsgna-armv7-tune.inc for more information

The following image-features are (re-)added:

• x11-base:
  Let systemd boot into grahical target

• volatile-log:
  If set, journal goes to volatile /run/log and /var/log is linked to /run/log
  which is volatile. NOTE: We change OE-Core’s default here: In bitbake.conf
  VOLATILE_LOG_DIR is enabled so that all images are build for volatile log.
  Since this is far off what others do change the default. See
  mortsgna-image-logfile-volatile.inc for more
  information.

This layer contains the following folders:

appends:

• All bbappends are stored in this folder. For each layer a sub-folder exists
  and the appends are dynamic: If a layer is not in bblayers.conf the folder
  for the layer is ignored (see conf/layer.conf).

classes:

• instant-sysroot-target.bbclass: Create a sysroot for target remote
  building/debugging - Yocto’s suggested workflows are cumbersome for ad-hoc
  usage.
• instant-sysroot-native.bbclass: Native recipes inheriting this class
  install everything necessary to run into a native sysroot. For a
  quick & minimal native SDK gcc-cross and gdb-cross inherit this class.
  class to enable instant remote debugging.
• user-with-full-skel.bbclass: Helper to populate /etc/skel in user’s
  home at image creation time.

conf:

• layer.conf / and distro configurations

recipes-defaultconfig:

• default configurations for lxqt and xfce to get a preconfigured
  environment. Note that all data is stored in th image at /etc/skel
• unpriv-user: A default non root user (named morona) member of many groups
  required for daily operations. It is shipped with home folder populated
  form /etc/skel.

recipes-image:

• All images for cinnamon / console / gnome / kde / lxqt / weston / xfce are found in this folder.
  allgui-images build images for all desktop environments.

recipes-utils:

• udev-rules-udisks-hide-bootpart: Hide boot partition from udisks
• Some tools (these are the only left from angstrom). Honestly: Have never
  used them but kept them if users come from angstrom and might miss
  them.

scripts:
A script collection

• to write images or kernel only to sdcards
• for changing recipe checksums automatically after version bump -> update-recipe-checksums.sh
