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.

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.

It's possible to know from which pool the nbuf comes from so
let's reduce nbuf size by removing its internal type attribute which
becomes then useless.
When a data buffer is not coming from nbuf data buffer pool, let's call
it "EXTERNAL", just to make debugging handling a little simple in the
code.

As the native IP stack is now the default, there is no need
for corresponding Kconfig option.

Provide an utility function that pushes data down in the fragment
chain which means that there would be some free space before the
first fragment.

Provide a function that checks if there is any free space
in the individual fragment and remove such slack. If there
are fragments that would become empty, then those fragments
are removed from the fragment list and freed to the fragment
pool.
