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.

We want to run a linter on CI submission.

We also want to display nice error messages to the user. Thus,
annoyatron is born.

The flow is as follows:
 - a MR is submitted and triggers the 'lint' pipeline
 - annoyatron gets pinged over https that an MR requires attention
 - annoyatron starts running and waits until the MR's pipeline run
   succeeds or fails
 - the lint jobs either succeeds or fails
 - annoyatron notices the pipeline passed, and inspects its results to
   see if the lint pipeline failed or not.
 - annoyatron posts a comment, if necessary

- The bootloader will now write files immediately, you
  no longer need to make sure you eject properly.
- *cardium is called l0dables and will definitely
  happen!
- External flash is now available from Pycardium

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/
