It is possible that the buffer waiting for retransmission is modified
after it is sent, for example, it can be compacted by 6lo, and our
assumption of where is the message ID is located in the buffer is no
longer valid.
As the message ID is the only information that is necessary for
keeping track of retransmissions, we keep a copy of it in the pending
struct, as well as the destination address of the retransmission.

Makes it cleared that zoap_update_from_block() doesn't modify the
packet.

This fixes the case that a request for block number (NUM) 0, using a
16 byte block was considered invalid.
This was because it is encoded as the value 0 (zero), which can be
expressed as the BLOCK1 option present but without any value
associated. The old code considered this the same as the option not
existing.

The returning 'len' was always informing the remaining available space
in that net_buf fragment. This not the expected behaviour for
incoming packets, in this case, we really want the size for the
payload already present in the packet.
When this function is called with a packet without a payload, with
will return the available space in the packet, when the payload is
already set, it will return the size of that payload.

In some situations, for example, when the remote side sends a RESET
message indicating that it is no longer interested in observing a
resource, it is helpful to have a way to obtain the obverser
representation.

When retrieving options that represent an integer, the order of the
bytes being considered was inverted, resulting in invalid values being
returned.

For example, when a RESET packet is passed to zoap_handle_request(),
there's nothing it can do, and it's not an error, so it returns
success silently.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.
