David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
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

* @file
* @brief Stack frame created by swap (IA-32)
*
* This file details the stack frame generated by _Swap() when it saves a task
* or fiber's context. This is specific to the IA-32 processor architecture.
*
* NOTE: _Swap() does not use this file as it uses the push instruction to
* save a context. Changes to the file will not automatically be picked up by
* _Swap(). Conversely, changes to _Swap() should be mirrored here if the
* stack frame is modified.
