Anas Nashif ca0ad13a61 net: enable SLIP only on QEMU targets
In many networking tests we had to configure SLIP in the prj.conf
leaving those configurations Qemu specific. This change enables SLIP for
QEMU targets automatically and allows reuse of prj.conf for multiple
boards.

Additionally, the TUN options is removed. This option was not used
anywhere.

To enable self-contained networking tests that do not depend on SLIP, we
introduce the new option NET_TEST which disables TAP and allows testing
in QEMU without the need for a host interface.

Tomasz Bursztyka bf964cdd4c net: Renaming net nbuf API to net pkt API
There have been long lasting confusion between net_buf and net_nbuf.
While the first is actually a buffer, the second one is not. It's a
network buffer descriptor. More precisely it provides meta data about a
network packet, and holds the chain of buffer fragments made of net_buf.

Thus renaming net_nbuf to net_pkt and all names around it as well
(function, Kconfig option, ..).

Though net_pkt if the new name, it still inherit its logic from net_buf.
'
This patch is the first of a serie that will separate completely net_pkt
from net_buf.

Jukka Rissanen 157c383260 net: ipv6: Make config options more fine grained
Add CONFIG_NET_IPV6_NBR_CACHE option that is the base for both
neighbor discovery (ND) and duplicate address detection (DAD).

Both ND and DAD can be disabled if needed. If NBR cache is
disabled, then ND and DAD are disabled too.

Note that it makes not much sense to disable DAD or NBR cache
as IPv6 will not work properly without them. It is possible
to disable ND but then the neighbor information needs to come
via other sources like RPL.

Jukka Rissanen ba5bb5a9df net: if: Join/leave pre-defined IPv6 multicast groups
When we setup the network interface, add predefined IPv6 multicast
groups into the network interface. When interface is taken down,
then leave all the multicast groups that joined.
See RFC 4291 ch 2.8 for details.

Jukka Rissanen d32503f57e net: nbuf: Split one global DATA pool to RX and TX DATA pools
If we receive lot of packets, it might happen that we exhaust
all the DATA buffers in the system. This would prevent from
us sending anything to the network.
Change this by splitting the DATA buffer pool into RX and TX
parts. This way RX flooding cannot consume all DATA buffers
that needs to be sent.

Marcus Shawcroft 954baea90b random: Restructure RANDOM Kconfig
Restructure the RANDOM Kconfig to match the structure used in other
drivers with a single top level menu.  Move the true random number
generators to appear first in the menu, with pseudo generators at the
bottom.  Do not present pseudo generators if a true random generator
is presented.

This change implies that tests, samples and applications that require
the random driver interface must now select CONFIG_RANDOM_GENERATOR.

In order for tests and samples to build (and run) on platforms that
have no random driver it remains necessary to select
the CONFIG_TEST_RANDOM_GENERATOR.

Note that CONFIG_TEST_RANDOM_GENERATOR retains its original purpose of
enabling a random driver that delivers non random numbers for the
purpose of testing only.

As the native IP stack is now the default, there is no need
for corresponding Kconfig option.

- new stack options are renamed and placed in their respective menus
- new stack Kconfig gets normalized (tabs vs spaces, etc...)
