On some boards, button 0 does not exist so BTN0_PIN is not defined, but
these boards may define other buttons.

This commit enables Cortex-M CPU interrupt sub-priorities
and allows the PendSV interrupt to have a priority different
from the default one. Together these two preprocessor
defines can be used to have PendSV always run as the last interrupt
before returning from the interrupt stack back to the user space.
Running PendSV as the last interrupt before returning to the
user space is recommended by ARM, as it increases efficiency.
Furthermore, that change enhances stability a lot with the
new nRF52 SoftDevice support, currently being worked in
PR #9473.
This commit merely enables sub-priorities and a separate
PendSV priority to be used without changing the default
RIOT behaviour.
There were two subtle bugs that prevented the DHCPv6 client to request
multiple prefixes for different interfaces.
- `dhcpv6_client_req_ia_pd()` would fill up *all* leases with the same interface
- `_parse_reply()` would return after parsing the first answer
With this patch, `gnrc_border_router` gets a prefix on both interfaces of the at86rf215.
One value in the output is possibly wrong, was left in the passing state
as the rest of the expected state reflects the same misconception, and
commented thusly.
Previously, when the creation of the TUN/TAP interface failed in one of
the `start_network.sh` scripts, the script will fail with a cryptic
error like
> dist/tools/ethos/start_network.sh: 68: [: -eq: unexpected operator
This fix ensures, that the value of this variable checked is always set
such that in the error case, `ethos`/`sliptty` won't start.
The DFLL on samd5x has a hardware bug that requires a special
re-enabling sequence when it is disabled and then re-enabled again.
When running the clock on-demand, the hardware handles the disabling
and re-enabling so that sequence does not get executed.
To reproduce, run `tests/periph_uart` on `same54-xpro`.
Without this patch the test will get seemingly stuck on `sleep_test()`.
(In fact it keeps running, but the DFLL has the wrong frequency so the
UART baudrate is wrong).
In this test, on `same54-xpro` only UART0 is sourced from DFLL.
So if the UART is disabled the DFLL will be turned off as well.
Switch from the on-chip LDO to the on-chip buck voltage regulator
when not fast internal oscillators are used.
On `saml21-xpro` with `examples/default` this gives
**before:** 750 µA
** after:** 385 µA
Proto files can include other proto files.
E.g. nanopb comes with a `nanopb.proto` include that contains some
nanopb-specific extensions.
This patch makes it possible to include this file as well as specifying
additional proto include folders.
I added the include to `simple.proto` so it gets exercised by the test.
