commit 79672d16 was missing the fact socket layer is putting net_pkt
into a k_fifo. However, it's on receiving side only: at this point the
k_fifo_put is using the k_work area which is then useless at this
point Thus why it did not break anything, as k_fifo only needs 4 bytes
while the k_work attribute takes 12 bytes.
Thus adding a union on the k_work attribute with another new attribute
that describes the behavior.

This attribute was used when net_pkt where queued into a fifo. However,
since the cove to k_work queues (due to the introduction of TC), such
attribute has been totally useless.
Removing it gains 4 bytes in net_pkt structure.

From POSIX.1-2017:
The getsockname() function shall retrieve the locally-bound name of the
specified socket, store this address in the sockaddr structure pointed
to by the address argument, and store the length of this address in the
object pointed to by the address_len argument.
The address_len argument points to a socklen_t object which on input
specifies the length of the supplied sockaddr structure, and on output
specifies the length of the stored address. If the actual length of the
address is greater than the length of the supplied sockaddr structure,
the stored address shall be truncated.
If the socket has not been bound to a local name, the value stored in
the object pointed to by address is unspecified.

sntp_simple() function queries the server (passed as "addr[:port]"
string). It wraps calls to a number of other functions, and may be
useful to write simple, concise apps needing the absolute time.

Two utils to manipulate addresses in format "addr[:port]". I.e.,
network address (domain name or numeric), optionally followed by
port number:
* net_addr_str_find_port(), to return pointer to port number
substring (or NULL if not present).
* net_getaddrinfo_addr_str(), which is effectively getaddrinfo()
wrapper taking a "addr[:port]" string as a parameter.
The header file is named socketutils.h to emphasize that these
utility functions are implemented on top of BSD Sockets API
(and other POSIX/ANSI C functions), and thus portable to other
POSIX systems (e.g., Linux), so can be used in apps testing
POSIX compatibility. More utility functions (beyond address
manipulation) can be added later.

Not in POSIX. Linux man getnameinfo says about it:
"In order to assist the programmer in choosing reasonable sizes for
the supplied buffers, <netdb.h> defines the constants
#define NI_MAXHOST 1025
#define NI_MAXSERV 32
Since glibc 2.8, these definitions are exposed only if suitable
feature test macros are defined, namely: _GNU_SOURCE, _DEFAULT_SOURCE
(since glibc 2.19), or (in glibc versions up to and including 2.19)
_BSD_SOURCE or _SVID_SOURCE."

It will help to use IS_ENABLED in place of #ifdef in relevant place.
Only struct net_if uses this structure.
In case only IPv4 is used, it will bloat up this struct by 12 bytes.
There are few reasons why this is "ok" in this case:
- On limited rom/ram system it will be unlikely to find a lot of
network interfaces so it should not harm much to raise the size of
struct net_addr.
- If IPv4 is the only enabled IP version, it gains a good amount of
rom/ram to discard IPv6 support so it is fine to steal a bit of this
gain to bloat up a bit struct net_addr.

The code (net_buf_simple_init in particular) expects the data buffer
to immediately follow the net_buf_simple struct, so it's wrong to
request any specific alignment for this buffer. In practice this
doesn't make any difference since the net_buf_simple struct itself is
4-bytes aligned and a multiple of 4 bytes, however the extra
__net_buf_align makes it look like its location in memory doesn't need
to immediately follow the net_buf_simple struct.
