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.

The tcp_synack_received() function ends with a call to send_ack().
However, if we don't update the sequence and ACK values, we'll send back
headers with 0 values and the destination will try resending over and
over.
Fix this by saving the seq and ack values when a TCP_SYN is flagged
in the header (which should be the case almost any time this function
is used as a callback).

On accepting a new connection, the stack does an odd "swap" trick
where it updates the struct net_tcp record on the *listening* context
with the values from the new connection, and then swaps it with the
empty one that got allocated for the *new* context.
Unfortunately this swap forgot to swap the net_tcp "context" field
backpointers, so the net_context retrieved at runtime was for the
wrong connection. Surprisingly, this actually almost worked for a
long time, except that the destination address would be wrong in the
newer setup.

The source address for a TCP SYNACK must (obviously) be the same as
the destination address of the SYN that produced it. But the existing
IP packet creation routines would simply fill in a default address
from the net_context struct, which is correct for *established*
connections, but for the listening socket is generally INADDR_ANY
(i.e. all zeroes) and will result in an arbitrary choice for source
address (e.g. a link-local address on the same interface) which can
easily be wrong.
So we need to pass the correct address all the way down from the SYN
packet handler code through the net_ipv*_create() packet creation
functions. This requires lots of API plumbing, but relatively little
logic change.

This commit adds one routine previously found at the DNS resolver
library. The net_nbuf_linear_copy routine allows to "linearize"
an IP stack network buffer. This routine is required by functions
that must jump between big chunks of data that in this case may
lie between many fragments. Tracking fragments may be a tedious
task, so getting a linear copy of the buffer will reduce code
complexity altough it increases memory consumption.
The DNS client library is updated to reflect these changes.

channels present in 2.4Ghz spectrum. However, this will need refinement
as soon as other spectrums will be in use: L2 layer could request

Let's make net stack having its own level of debugging through sys_log.
It replaces NET_DEBUG by NET_LOG_ENABLED, which is then semantically
better: someone wanting to log the errors might want that not only for
debugging.
Along with it, CONFIG_NET_LOG_GLOBAL option is added, in order to enable
all available logging in network stack. It is disabled by default but
might be found useful when warning/errors need to be logged, so it is
then unnecessary to selectively enable by hand all CONFIG_NET_DEBUG_*
options.
It is possible, locally, to override CONFIG_SYS_LOG_NET_LEVEL by setting
the level one want to NET_SYS_LOG_LEVEL. This can be useful on samples
or tests.
