This is the first commit from the set of patches that brings to the
Zephyr, SO_TIMESTAMPING socket level option. This enables to pass to
the network driver information whether given network packet should
be timestamped or not.

From change 47eb592c28b9e7dfbdd25fedbf07a528ad240084 net_buf structures
allocated from pools defined with NET_BUF_POOL_FIXED_DEFINE() will keep
their `size` member set to the actual fixed size and not requested
size like before.
For this set of tests NET_BUF_POOL_FIXED_DEFINE() for several test
cases. These tests check the several values based on a fact that the
network buffer's size was set to the requested size.
This commit changes definition of the buffer pool to
NET_BUF_POOL_FIXED_DEFINE() in order to satisfy these expectations.
This change does not impact the tests themselves.

rand32.h does not make much sense, since the random subsystem
provides more APIs than just getting a random 32 bits value.
Rename it to random.h and get consistently with other
subsystems.

For socket families that are niether INET/INET6 e.g., PACKET, we cannot
estimate header length, so, if the payload is zero as well, networking
stack drop the packet.
Instead, allow for zero header + payload packets and let L2 take care of
handling them, for some L2's this is still a valid frame.
E..g, In case of Wi-Fi this is sent as 802.11 Header + LLC Header
(no payload).
Add unittests for both AF_INET + Zero payload and AF_PACKET + Zero
payload.

The net packet structure contains pointers to link-layer source and
destination addresses. Usually, these structures do not point to
separately allocated memory but directly into the packet's data buffer.
In case of a deep package clone (which includes copying the buffer) the
copy of the ll addresses continued to point into the old package
(contrary to a rather misleading inline comment). This was proven by an
additional failing unit test assertion.
As the original package may be unreferenced while the cloned package is
still being accessed, the ll address pointers of the cloned package may
become invalid.
The fix consists of two parts:
* First it is determined whether a given ll address actually points into
the buffer and if so at which logical cursor offset it is located.
* If the address points into the package buffer then the cursor API is
used to determine the corresponding physical memory location in the
cloned package. The ll address of the cloned package is then patched
to point to the cloned buffer.
Additional assertions were introduced to the existing unit test to ensure
that the newly generated address points to the correct content of the
cloned package.
The solution is implemented in a generic way so that the previously
redundant implementations were consolidated into a single one. The code
includes a check that ensures that the ll address check and manipulation
will be skipped in case of shallow package copies.
The change also addresses problems related to the "overwrite" flag of the
package:
* Package cloning assumes the overwrite flag to be set. Otherwise it
will not work correctly. This was not ensured inside the clone method.
* Package cloning manipulates the overwrite flag of the cloned package
but does not reset it to represent the same state as the original
package.
The change introduces a fix and unit test assertions for both problems.
