build: add preliminary LGPL mode
See "Copyright" file for caveats. This changes the remaining "almost LGPL" files to LGPL, because we think that the conditions the author set for these was finally fulfilled.

Some libraries are GPLv2+ or GPLv3+ only. Building mpv with Samba support makes

+mpv can be built as LGPLv3+ with the --enable-preliminary-lgpl3 configure
+option. This is a very new switch and it hasn't been confirmed yet whether
+really all GPL code is excluded (thus preliminary). In addition, it disables
+a number of useful features, some of them quite central:
+- no audio filtering, which breaks: --volume, --af, replaygain, pitch
+ correction, fine control about downmix/upmix/resampling behavior
+- Linux X11 video output
+- Linux audio output via ALSA (PulseAudio works)
+- BSD audio output via OSS
+- Linux hardware decoding (vaapi, vdpau)
+- many builtin video filters (use libavfilter instead)
+- automatic rotation and stereoscopic video handling
+- Linux TV input
+- the --frames option
+- the add/cycle and sub-add/audio-add/sub-remove/audio-remove commands
+- video format conversion (if not supported by the VO)
+- minor features: jack, DVD, CDDA, SMB, CACA, legacy direct3d VO
+Some of these will be fixed in the future. The lack of the add/cycle commands
+makes this particularly useless for CLI mode, and most of the appeal of LGPL
+is for libmpv anyway. Thus it's not recommended to build mpv CLI in LGPL mode
+at all.
