wm4 642e963c86 dec_video: change license to LGPL (almost)
"Almost" because this might contain copyright by michael, who agreed
with LGPL, but only once the core is LGPL. This is preparation for that
to happen.

Apart from that, the usual remarks apply. In particular, dec_video.c
started out quite chaotic with no modularization, but was later
basically gutted, and in general rewritten a bunch of times. Not going
to give a history lesson.

Special attention needs to be given to 3 patches by cehosos, who did not
agree to the relicensing:

240b743ebdf: --field-dominance
e32cbbf7dc3: reinit VO if aspect ratio changes
306f6243fdf: use container aspect if codec aspect unset (?)

The first patch is pretty clearly still in the current code, and needs
to be disabled for LGPL.

The functionality of the second patch is still active, but implemented
completely different, and as part of general frame parameter changes (at
the time of the patch, MPlayer already reinitialized the VO on frame
size and pixel format changes - all this was merged into a single check
for changing image parameters).

The third patch makes me a bit more uncomfortable. It appears the code
was moved to dec_video.c in de68b8f23c, and further changed in
82f0d373, 0a0bb905, and bf13bd0d. You could claim that cehoyos'
copyright still sticks. Fortunately, we implement alternative aspect
detection, which is simpler and probably preferable, and which arguably
contains none of the original code and logic, and thus should be fully
safe.

While I don't know if cehoyos' copyright actually still applies, I'm
more comfortable with making the code GPL-only for now. Also change the
default to use the (in future) plain LGPL code, and deprecate the one
associated with the GPL code, so we can eventually remove the GPL code.

But it's also possible we decide that the copyright doesn't apply, and
undo the deprecation and GPL guards.

I expect that users won't notice anything. If you ask me, the old aspect
method was probably an accidental bug instead of intentional behavior.

Although, the new aspect method was broken too, so I had to fix it.
