This adds the SPDX-License-Identifier license headers to the majority of our source files to make it clearer exactly which license files are under. The bulk of the files are under GPL v2.0 with one found to be under V2.0 or later, some under MIT and some have dual license. There are some files which are potentially harder to classify where we've imported upstream code and those can be handled specifically in later commits. The COPYING file is replaced with LICENSE.X files which contain the full license texts.

The bitbake server takes 'commands' from its UI/commandline.
|
|
Commands are either synchronous or asynchronous.
|
|
Async commands return data to the client in the form of events.
|
|
Sync commands must only return data through the function return value
|
|
and must not trigger events, directly or indirectly.
|
|
Commands are queued in a CommandQueue
