libc: rework libc selection and reduce Kconfigs Moved all libc Kconfigs to where the code is and remove the default Kconfig for selecting the minimal libc. Minimal libc is now the default if nothing else is configured in. Removed the options for extended libc, this obviously was restricting features in the minimal libc without a good reason, most of the functions are available directly when using newlib, so there is no reason why we need to restrict those in minimal libc.

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.

This option directs standard output (e.g. printf) to the console
device, rather than suppressing it entirely. See also EARLY_CONSOLE
option.
