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.

net: Add initial generic buffer implementation We need to have a generic buffer API in order to efficiently transfer data between different subsystems. The first such case will be the Networking and Bluetooth subsystems where 6LoWPAN data will be passed back and forth. The needed API needs to provide enough flexibility for different buffer sizes as well as custom protocol-specific context data. The implementation offered in this patch follows the general design of the existing Networking and Bluetooth buffer implementations by using a backing array of buffer which is fed into a "free buffers" FIFO for management. The main difference is that the API allows specifying variable sized buffers for each created pool, as well as a minimum amount of "user data" that's allocated as part of each buffer. There's also an optional destroy callback that's e.g. useful for HCI flow control in Bluetooth (for notifying the controller of available buffers).

net: buf: Fix NET_BUF_USER_DATA_SIZE value for Bluetooth For 32-bit architecture Bluetooth only requires 4 bytes for the user data. There are places that store a pointer in it, so we need to make an exception for 64-bit architecture. The code contains relevant build asserts, so it's sufficient to set a conditional default in Kconfig but let the range definition be simpler (unconditional). Also simplify & fix the conditional defaults & ranges. E.g. separately mentioning X86_64 is redundant since that option explicitly selects the 64BIT option.
