core: add infrastructure to get screenshots from VOs Add a VO command (VOCTRL_SCREENSHOT) which requests a screenshot directly from the VO. If VO support is available, screenshots will be taken instantly (no more 1 or 2 frames delay). Taking screenshots when hardware decoding is in use will also work (vdpau). Additionally, the screenshots will now use the same colorspace as the video display. Change the central MPContext to be allocated with talloc so that it can be used as a talloc parent context. This commit does not yet implement the functionality for any VO (added in subsequent commits). The old screenshot video filter is not needed anymore if VO support is present, and in that case will not be used even if it is present in the filter chain. If VO support is not available then the filter is used like before. Note that the filter still has some of the old problems, such as delaying the screenshot by at least 1 frame.

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.)

There's no reason to have the command handlers themselves in command.c, with a weird under-defined API in between. (In the future, I'd like to split up command.c further, and when I do that, scrrenshot.c will probably gets its own mp_cmd_def[] array, and define the commands locally instead of exporting the raw handlers.)
