Replace most BSD 3-clause license text with SPDX identifier. Many open source projects have moved to using SPDX identifiers to specify license information, reducing the amount of boilerplate code in every source file. This patch replaces the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause identifier. Almost all of these files share the exact same license text, and this patch only modifies the files that contain the most common license text. There can be slight variations because the third clause contains company names - most say "Intel Corporation", but there are instances for Nvidia, Samsung, Eideticom and even "the copyright holder". Used a bash script to automate replacement of the license text with SPDX identifier which is checked into scripts/spdx.sh.

ftl: Initial implementation This patch adds core FTL (flash translation layer) submodules. On regular SSDs the FTL is part of firmware, whereas Open Channel enables moving it to the host and allows for having full controll of data placement on the device.

ftl: Gathering asynchronous NAND management events The patch adds support for retrieving asynchronous media management events sent by the drives. SSDs needs to inform the host of various incidents concerning the data placed on the media. The events include wear-leveling, read disturb, and background data refresh. In order to poll for this asynchronous events, a separate thread is added that polls for completion of admin commands for each of Open Channel disk and dispatches the ANM events to the appropriate block devices.
