This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t. This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.
We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.
We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

This does not save any space but sets the fields in the
structs in more natural order. Move IPv6 related
fields in net_if into internal ipv6 struct so that all
IPv6 fields are located inside one struct. Same thing
is done for IPv4 fields which are now located inside
IPv4 internal struct in net_if.
There is no functionality changes by this commit.

If IPv6 DAD (Duplicate Address Detection) succeeds or fails,
we send a management event for that. This can be used by

This makes net_ipv6_nbr_add able to update entries so it can be reused

Following changes are made:
1. Output using NET_INFO logging level. This function is not part of
automatic logging, and must be called explicitly by a user application.
But if it outputs using NET_DEBUG, then DEBUG level needs to be
enabled, and the output of this function will be drowned in logging
spam. So, let user to enable just INFO level.
2. Show entire structure of the fragment chain, *including* the head
net_buf which holds net_nbuf structure. It is numbered as -1 in the
output to preserve existing order (and not change existing size
calculations).
3. Show owning pool (and its properties, like buffer size/user_data
size) for each buffer.
4. Check for NULL pointer, e.g. for convenience of calling directly
from net_context receive callback (which will be called with NULL
on TCP peer closed connection event).
With these changes, a newcomer from one look at the output of this
function will be able to have a clear basic picture of network
buffer management in Zephyr, and recurring user will be able to
recall any details at once.
