wm4 b537b59e65 msg.c/h: partially change license to LGPL
msg.c is "partial" due to "michael", whose work can be changed to LGPL
only once the core is LGPL. It's explained in the Copyright file. I
prefer to do the relicensing incrementally (due to the overwhelming
workload). Changing the license before that happens would be legally
questionable, but nothing can stop us from essentially marking it as
"will be LGPL".

All authors have agreed to LGPL, with the following exceptions:

9df11ee8bf: the author (probably) didn't agree, but the line that is
added is later fully removed.

35e90f1556: was not asked, but all iconv code was 100% removed from the
mp_msg mechanism (we alwas require UTF-8 now).

4e4f3f806e: the change by michael.

50a86fcc34: the identify variable was move, and completely removed the
latest in commit 48bd03dd91.

1f6c494641: did not agree, but due to a major mp_msg change the added
line became unnecessary and was removed.

da63498bf9: was not reachable, but the MPlayer GUI is gone from mpv
anyway (also commit fc4d6e617d removed these specific additions a long
time ago).
