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.

When a CNAME is part of the DNS answer RR, sometimes a label with
a pointer is found. The CNAME must be reused to create a new DNS
query and that CNAME will become the new DNS Query QNAME. This new
QNAME must not include pointers.
This patch introduces the qname_copy routine that "linearizes" a
given QNAME (perhaps with pointers).
The dns_read routine is also updated to reflect these changes.

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.
