As a step to completing removing use of Kconfig defines in dts files we
need to change how we configure/set CONFIG_FLASH_LOAD_{OFFSET,SIZE}.
Previously we would set them based on how the chosen property
'zephyr,code-partition' was set to. If 'zephyr,code-partition' wasn't
set we would default the values to 0. We had some generic overlay logic
which would define 'zephyr,code-partition' based on
CONFIG_BOOTLOADER_MCUBOOT.
Going forward if the DTS has 'zephyr,code-partition' set we will
generate DT_CODE_PARTITION_OFFSET & DT_CODE_PARTITION_SIZE defines. We
will leave it to Kconfig to set CONFIG_FLASH_LOAD_OFFSET &
CONFIG_FLASH_LOAD_SIZE.
We introduce a python script that allows Kconfig to extract data from
the DTS and thus we can utilize DT_CODE_PARTITION_OFFSET and
DT_CODE_PARTITION_SIZE values to set defaults for
CONFIG_FLASH_LOAD_OFFSET & CONFIG_FLASH_LOAD_SIZE.

As we want to remove dts dependency on Kconfig, we had a case based on
CONFIG_BOOTLOADER_MCUBOOT. From a DTS point of view that was just
getting the chosen property 'zephyr,code-partition' set. We can easily
move this to the actual dts files and remove the mcuboot.overlay.

The gpio_port_ functions provided by the gpio API do not provide
currently a mask parameter. As such they operate on a full port only.
In practice such functions are not useful. This commit deprecates them
to allow adding port functions with support for a mask parameter in the
future.

This commit implements a CTF-backend for Zephyr's tracing API.
The CTF-backend itself is split in a middle-layer and a bottom-layer.
- Middle-layer decides the payload in event transactions,
- Bottom-layer implements the IO transport.
A simple POSIX bottom-layer is provided so far.

If status is 0, both ip_hdr and proto_hdr will own a pointer to the
relevant IP and Protocol headers. In order to know which of ipv4/ipv6
and udp/tcp one will need to use respectively net_pkt_family(pkt) and
net_context_get_ip_proto(context).
Having access to those headers directly, many callbacks will not need
to parse the packet again no get the src/dst addresses or the src/dst
ports. This will be change after this commit.

Though these are currently used by the core only, it will be then used

Now that net_pkt are accessed through a common r/w API, using below a
net_pkt_cursor, let's have an option that will reset this cursor once
the net_pkt is freed.
Result is instead of segfaulting on r/w access, these operations will
bail out properly. Subsequent, and logical (unless you have a leak
which is another issue) net_pkt_unref will tell you who/where the pkt
was freed. Without it, you will get a segfault for instance, but that
won't tell you the exact reason. This options can help you then.

The test counts the '\0' of the data copied, though it does not belong
to the packet.
Since the test by-passes net_ipv6_input, which would update the packet
length according to what is in the IPv6 header, the checksum calculation
fails.
Before, checksum calculation used to grab the length from IPv6 header,
but that changed to use net_pkt_get_len(): that one must provide the
real lenth.

Most of the code had to be reworked due to the new API: it's more
logical to do everything sequentially (first headers, then MLD part)
than the contrary with inserting headers at the end.
Using get_data/set_data as well it makes the code clearer.

Also, return a verdict instead of a pointer to net_pkt. It's simpler as
it will be up to net_send_data()'s caller to unref the net_pkt in case
of NET_DROP: less places where net_pkt can be unref.

Reworking the logic to reduce the amount of variables.
Introducing a generic struct to acces the common part of MLD queries,
instead of accessing part by part.
Also, returning NET_OK in case parsing went fine. We send an MLD report
anyway, so it's not a good idea to count the message as being dropped in
statistics.
