Relicense some non-MPlayer source files to LGPL 2.1 or later
This covers source files which were added in mplayer2 and mpv times
only, and where all code is covered by LGPL relicensing agreements.
There are probably more files to which this applies, but I'm being
conservative here.
A file named ao_sdl.c exists in MPlayer too, but the mpv one is a
complete rewrite, and was added some time after the original ao_sdl.c
was removed. The same applies to vo_sdl.c, for which the SDL2 API is
radically different in addition (MPlayer supports SDL 1.2 only).
common.c contains only code written by me. But common.h is a strange
case: although it originally was named mp_common.h and exists in MPlayer
too, by now it contains only definitions written by uau and me. The
exceptions are the CONTROL_ defines - thus not changing the license of
common.h yet.
codec_tags.c contained once large tables generated from MPlayer's
codecs.conf, but all of these tables were removed.
From demux_playlist.c I'm removing a code fragment from someone who was
not asked; this probably could be done later (see commit 15dccc37).
misc.c is a bit complicated to reason about (it was split off mplayer.c
and thus contains random functions out of this file), but actually all
functions have been added post-MPlayer. Except get_relative_time(),
which was written by uau, but looks similar to 3 different versions of
something similar in each of the Unix/win32/OSX timer source files. I'm
not sure what that means in regards to copyright, so I've just moved it
into another still-GPL source file for now.
screenshot.c once had some minor parts of MPlayer's vf_screenshot.c, but
they're all gone.

screenshot: make screenshot filenames configurable
This adds the --screenshot-template option, which specifies a template
for the filename used for a screenshot. The '%' character is parsed as
format specifier. These format specifiers insert metadata into the
filename. For example, '%f' is replaced with the filename of the
currently played file.
The following format specifiers are available:
%n Insert sequence number (padded with 4 zeros), e.g. "0002".
%0Nn Like %n, but pad to N zeros (N = 0 to 9).
%n behaves like %04n.
%#n Like %n, but reset the sequence counter on every screenshot.
(Useful if other parts in the template make the resulting
filename already mostly unique.)
%#0Nn Use %0Nn and %#n at the same time.
%f Insert filename of the currently played video.
%F Like %f, but with stripped file extension ("." and rest).
%p Insert current playback time, in HH:MM:SS format.
%P Like %p, but adds milliseconds: HH:MM:SS.mmmm
%tX Insert the current local date/time, using the date format X.
X is a single letter and is passed to strftime() as "%X".
E.g. "%td" inserts the number of the current day.
%{prop} Insert the value of the slave property 'prop'.
E.g. %{filename} is the same as %f. If the property doesn't
exist or is not available, nothing is inserted, unless a
fallback is specified as in %{prop:fallback text}.
%% Insert the character '%'.
The strings inserted by format specifiers will be checked for
characters not allowed in filenames (including '/' and '\'), and
replaced with the placeholder '_'. (This doesn't happen for text that
was passed with the --screenshot-template option, and allows specifying
a screenshot target directory by prefixing the template with a relative
or absolute path.)

player: make screenshot each-frame mode more accurate
Due to asynchronicity, we generally can't guarantee that a video frame
matches up with other events such as playback time change exactly (since
decoding, presentation, and property update all happen at different
times). This is a complaint in the referenced bug report, where
screenshot filenames in each-frame screenshot did not use the correct
timestamp, and instead was lagging behind by 1 frame.
But in this case, synchronicity was already pretty much forced with wait
calls. The only problem was that the playback time was updated at a
later time, which results in the observed 1 frame lag. Fix this by
moving the place where the screenshot is triggered in this mode.
Normal screenshots may still have the old problem. There is no effort
made to guarantee the timestamps absolutely line up, same as with the
OSD. (If you want a guarantee, you need to use a video filter, such as
libavfilter's drawtext. These will obviously use the proper timestamp,
instead of going through the somewhat asynchronous property etc. system
in the player frontend.)
Fixes: #7433
