LICENSE: switch to LGPLv2.1

[jcpunk]

One of the source files lists APL2 another lists GPL2, others have no identification. Can the license information be clarified for this code?

[jsorg71]

Yes, I noticed that too. Since these modules run in process and pulseaudio is GPL2 I guess they should all be GPL2.

Ideally, we need to get approval of re-definite license from all contributors however, fortunately, more than 80% of commits are made by Jay and speidy and me. The rest commits are only 10. If the changes are trivial enough, license change can be done without their approval.

At least I'm OK with changing everything I contributed to GPLv2.

Update:

I've looked through all commits, I think we can change the license.

metalefty, jsorg71, speidy and LK2000 are members of the xrdp project. So we don't need to get approval of these 4 of us.

NatureShadow contributed 1 commit but it was a simple document change. proski is a former outside contributor but his contributions are also very simple. CI fixes, suppress warnings and updating gitignore.

I noticed PulseAudio's license has been changed to LGPLv2.1.
