ld emits relocations for weak undefined symbols. We want to safely skip
them.

This lets us decide where the stack live, and place it at the best
possible spot for it to grow towards the image.

This is the first step towards having a heap in l0dables.

Make the flow-diagram correctly show that Epicardium will create
`menu.py` if none was found on the external flash.  This means,
the menu will always be run from `menu.py`.

The 3rd core is not used for BLE as of now so we should not document it
as such.  This commit also updates the colors of Epicardium and
Pycardium to match the rest of the docs & GitLab.

Plug in a new SDK with improved BLE support (more source files
available)

Does not yet actually us BLE.

We decided to merge the implementation ASAP so we can build other
features ontop of it.  Further cleanup and refactoring of the modules
will now happen in separate patches.

The Epicardium API for this module will not change that much from what
it looks like now.

Other existing API calls also use raw `int` for descriptors
so I think we should use it for file-functions as well.

The same commands can be used on Ubuntu and Debian stable. Debian stable
ships meson 0.49.2 which should be sufficient.

We provide a nix expression to build card10 firmware.

On Linux/Darwin with Nix and NixOS, this can be used as follows:

  $ git submodule update --init
  $ nix build
  $ ls result/
  result/bootloader:
  bootloader.elf

  result/epicardium:
  epicardium.elf

  result/pycardium:
  pycardium.elf  pycardium_epicardium.bin

This derivation can also be used for development:

  $ nix-shell
  $ meson --cross-file card10-cross.ini build/
  $ ninja -C build/ -j8
  $ # hack on things
  $ ninja -C build/ -j 8
  $ ls build/
  [ ... ]

is the current de facto standard to get bash somewhat universally.

Manual merge for !37

In this change we modify the CI pipeline to use pre-built Docker images
for both build and deploy stages.  To this end, we create
`docker/{build-env,deploy-env}`, two directories containing Dockerfiles
describing how to build those images, and scripts to push them to a
Docker registry.

Currently, docker.card10.badge.events.ccc.de seems broken. Thus, we push
to the Warsaw Hackerspace Docker registry.  Since the Docker images will
be pulled rarely anyway (as they are cached by build nodes), any low
bandwidth-caused slowdowns will not be usually end up in the CI critical
path.

We also bump `.gitlab-ci.yml` to point to those new images.
