Python3 has been the default in our scripts for some time now, but pyterm still
requested python which uses python2 on ubuntu stable.
This pushes toward only needing to install `python3` python
dependencies.
Change description to reflect the configurability of the serial
interface.
Also, fix the uart_mode parameter description as the UART will be
configured and not initialized.

Usually, all .rodata sections are placed in RAM by the Espressif SDK since IROM (flash) access requires 32-bit word aligned reads. thanks to the LoadStoreError exception handler from esp-open-rtos which is used now in RIOT-OS, it is also possible to place .rodata sections in IROM (flash) to save RAM resources.
Usually, the access to the IROM (flash) memory requires 32-bit word aligned reads. Attempts to access data in the IROM (flash) memory less than 32 bits in size triggers a LoadStoreError exception. With the exception handler from esp-open-rtos it becomes possible to access data in IROM (flash) with a size of less than 32 bits and thus to place .rodata sections in the IROM (flash).
To be able to include *_params.h in docuementation, STRIP_FROM_INC_PATH has to be empty. Otherwise, a number of warnings are thrown if *_params.h files with same names exist in different directories.
The `_next_removable` list manages the cache-out of the neighbor cache.
However, when a neighbor cache entry is removed, it is not removed
from that list, which may lead to a segmentation fault when that list is
accessed, since the whole entry (including its list pointer) is zeroed
after removal.
With this change the entry is removed from that list accordingly before
the zeroing happens.
Cenk and I put some effort into making 6LoWPAN work without IPv6; except
for when used with the IPv6 header compression of course. This is why
`gnrc_ipv6` is only really *required* by `gnrc_sixlowpan_iphc` now.
With this change the `gnrc_ipv6` dependency is moved from the
`gnrc_sixlowpan` module to the `gnrc_sixlowpan_iphc` module.
Features must be provided by the board if they're actually
available on board. Other features might be provided by the
CPU.
Some grouping is also removed as it is not necessary.
Leverages common flasher (avrdude) and removes unnecessary exports.
Moreover, a reuse of serial.inc.mk is perfomed from the same
atmega_common/Makefile.include
Allows to use avrdude as a flashing tool in any context
(e.g. not dependent on arduino or atmega) though it only
works (AFAIK) on atmega, but I thought it's better to
have it here as we have other flashing tools.
When either `gnrc_sixlowpan_iphc_nhc` or `gnrc_udp` is not compiled
in `_compressible()` never returns `true`. This causes the
`dispatch` snip in `gnrc_sixlowpan_iphc_send()` to be of length 0,
meaning `dispatch->data` is `NULL`, causing possible crashes when
trying to send IPv6 packets over 6LoWPAN without NHC or UDP.
