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. Jira: ZEP-1457 Change-Id: I6131a1d4ee0e58f5b938300c2d2fc77d2e69572c Signed-off-by: David B.
