The comment exists since the introduction of the [original
implementation], but its meaning is unclear and misleading, as the code
doesn't do anything with link-local.

Rule 2 of the source address algorithm outlined in [RFC6724] states the
possible source addresses must also be compared among each other:
> Rule 2: Prefer appropriate scope.
> If Scope(SA) < Scope(SB): If Scope(SA) < Scope(D), then prefer SB and
> otherwise prefer SA. Similarly, if Scope(SB) < Scope(SA): If
> Scope(SB) < Scope(D), then prefer SA and otherwise prefer SB.
Our current implementation doesn't do that. It just checks if the scope
of a possible source is lesser than the scope of the destination
(which involves the second "If" in the rule).
This fix grants points according to the scope of an address. If the
scope matches, they get the highest points, ensuring that the selected
source will always be reachable from the destination.

pic32 boards now provide an UART, and this the periph_uart feature
ruuvitag/thingy52 provide the periph_uart feature so stdio_uart can work
on these boards.
chronos is indirectly blacklisted because of missing periph_uart feature.
hamilton doesn't provide periph_uart when stdio_rtt is disabled (because
of ethos dependency to stdio_uart) and ruuvitag/thingy52 provide the
periph_uart feature so stdio_uart can work on these boards.
When generating the doxygen output the temp sens and offset are in the config group.
Since they are internal parameters not to be accessed by users they are placed in the mpu9x650_internal.h file.
Since the GNRC_IPV6 is part of GNRC it should be a part of the gnrc compile time configuration group.
This adds information on the group to specify it is gnrc and changes the group from config to net_gnrc_conf
With the introduction of BOARDSDIR external boards can re-use common
code of BOARDS present in RIOTBASE. To be able to do this file
references may not use $(BOARD) since BOARD will be set by the
external BOARD.
