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

Title: Logger application hook sample

Description:

A simple example on how to use logger hook in order to redirect the logger
output to various backends.
In this case, the logger is sending the output to ringbuf,
logger output can be sent to a driver such as UART / USIF etc. as well.

This unified project outputs to the console.
It can be built and executed on QEMU as follows:

    make run

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info

Sample Output:

[sample-unified] [ERR] main: SYS LOG ERR is ACTIVE
[sample-unified] [WRN] main: SYS LOG WRN is ACTIVE
[sample-unified] [INF] main: SYS LOG INF is ACTIVE
