sensors: add driver for DHTxx sensors Add driver for the DHT temperature and relative himidity sensor family. The sensor has a single signal pin (in addition to GND and VDD) over which communication is done in a half-duplex manner (see datasheet for more details).

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.

logging: move sys_log to subsys/logging Move logging out of misc/ to its own subsystem. Anything related to logging and any new logging features or backends could be added here instead of the generic location in misc/ which is overcrowded with options that are not related to eachother.
