The current implementation uses the assumption that the IPv6 address is
always based on an EUI-64, which it doesn't has to.

gnrc_ipv6_ext: use send for forwarding with RH

gnrc_netif: add general IID to/from l2addr conversion functions

gnrc_ndp: make compilable for router without ARSM

Makefile.include: building in docker should be done after clean 

Though this change might seem more complicated, it has the benefit, that
after #9484 we don't have to assume that a received packet within IPv6's
receive function can be handed to the function pre-parsed, making that
function far less complicated (will be provided in a future PR).

Also this might give the forwarding via routing header a little
performance boost, as we now don't *receive* the packet first only to
forward it later-on.

They are required to make GNRC's 6Lo IPHC implementation ready for
hardware addresses other than IEEE 802.15.4's.

boards/{firefly,samr30-xpro}: add missing `periph_gpio_irq` provided feature

cpu/esp8266: fix of adc_res_t

When building in parallel, clean is done at the same time as the
container starts building.

So the parallel `clean all` handling should also be done for the
`..in-docker-container` target.

make: fix BUILD_IN_DOCKER when RIOT is submodule

periph/uart: fix line length in doc header

tests/xtimer_now64_continuity|xtimer_usleep: disable running test on native

openocd: get flash and debug files from cli

gnrc_netif: make link-layer specific operations proper submodules

mcuboot.mk: Add mcuboot targets to BUILDDEPS.

The test randomly fails for unrelated PRs. Expecting real-time timing on
native is not really possible. Maybe it could be fixed but it currently
triggers many false positive.

When doing `make -j clean all' the directories can be cleaned after
files are made. To ensure files are created after clean, those targets
are made conditionally dependent on the clean target.

This copies the handling done in Makefile.include.

eclipse.inc.mk: Split eclipse support into it's own file.

Get FLASH_FILE from command line instead of environment variable.

The documentation was claiming ELFFILE was given as a command line argument
already, but is was not.

This is the same change as with `openocd.sh`.

Get FLASH_FILE and ELFFILE from command line instead of environment variable.

The documentation was claiming ELFFILE was given as a command line argument
already, but is was not.

To keep Makefile.include clean and to be consistent with other tools,
the Eclipse IDE support is put in a separate file.

No that we introduced sub-modules to `gnrc_netif` we can move that here
as well.

gnrc_netif_hdr: provide convenience function to get netif pointer from netif header.

drivers/periph_eeprom: add clear and erase functions

shell_commands/ifconfig: mark TENTATIVE addresses correctly
