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.

Introduce new sized integer typedefs This is a start to move away from the C99 {u}int{8,16,32,64}_t types to Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t. This allows Zephyr to define the sized types in a consistent manor across all the architectures we support and not conflict with what various compilers and libc might do with regards to the C99 types. We introduce <zephyr/types.h> as part of this and have it include <stdint.h> for now until we transition all the code away from the C99 types. We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some existing variables defined u8 & u16 as well as to be consistent with Zephyr naming conventions.

gpio: Improve the public API to handle multi callbacks Many sub-systems might require to set a callback on different pins. Thus enabling it via changing the API. It is also possible to retrieve private-data in the callback handler using CONTAINER_OF() macro (include/misc/util.h). Former API is still available, and is emulated through the new one. Using both should not be a problem as it's using new API calls. However, it's now better to start using the new API.
