081246737c net/http: let HTTP_SERVER, HTTP_CLIENT and HTTP_PARSER select HTTP
Due to commit 8308b9bd2d ("net/http: Add the HTTP/1.1 API")
every user of CONFIG_HTTP_PARSER would need to add CONFIG_HTTP to
their .conf files.  Which is fine for intree samples/tests as they
have been adjusted, but the rest of world working on Zephyr apps
will need to make this changes as well.

Instead, we should have each of the following select HTTP instead of
depend on it, which will make future use of these configs and their
dependencies more intuitive:
HTTP_SERVER
HTTP_CLIENT
HTTP_PARSER

NOTE: As cleanup, this commit also removes the CONFIG_HTTP added to
samples and test .conf files.

c54b3c7e8f drivers: Update Atmel SAM family GMAC Ethernet driver
Networking stack has split one global DATA pool to RX and TX DATA pools
and also added net_buf pool support to each context. Update the driver
to support this new design. Since the GMAC TX descriptor list has a fixed
size but the number of TX DATA buffers is no longer limited updating the
TX descriptor list has to be guarded by a semaphore.

Tested on Atmel SMART SAM E70 Xplained board

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.

e1a6c7d472 drivers: slip: Allow specifying the MAC address from config file
The current state of affairs will not allow to set a MAC address and
thus will initialize a random MAC address.

However, when we are in a situation where we are trying to interface
Zephyr OS QEMU VMs with physical targets for testing, this is not
practical. We need to create a macvtap interface, on which we need to
set the MAC address of the Zephyr OS SLIP device so packets can be
routed.  There is no way to guess which random address is going to be
used, and there is no practical way to query it.

So this patch adds a CONFIG_SLIP_MAC_ADDR config
setting. slip_iface_init() is changed to take the code from
slip_get_mac() for initializing the MAC address (which should be
happening there anyway) and if CONFIG_SLIP_MAC_ADDR is set, it takes
that one -- otherwise goes to generate a random one.

d6d1b3a748 net/mgmt: Add a network interface based synchronous event listener
In case of callback based event listener, it is easy for the callback to
filter on the given interface. But in case of the synchronous call it's
not: it would need, after a failed comparison on the interface pointer
to loop by itself on the net_mgmt_event_wait() which is a little bit
heavy (reinstalling the event listener, with the semaphore and all) and
a bit of a burden for the caller itself.

Instead, net_mgmt provides a dedicated call
net_mgmt_event_wait_on_iface() which does it the right way, so the
callback and the related semaphore are destroyed if only the iface
matches the one given as parameter (besides the timeout obviously).
