vo_opengl: split into multiple files, convert to new option API gl_video.c contains all rendering code, gl_lcms.c the .icc loader and creation of 3D LUT (and all LittleCMS specific code). vo_opengl.c is reduced to interfacing between the various parts.

vo_opengl: add support for in memory icc profiles Previously we just forced loading a profile from file, but that has poor integration for querying the OS / display server for an ICC profile, and generating profiles on the fly (which we might use in the future for creating preset 3dluts). Also changed the previous icc-profile-auto code to use this mechanism, and moved gl_lcms to be an opaque type with state instead of just providing pure functions.

vo_opengl, cocoa: allow to autoselect a color profile This commit adds support for automatic selection of color profiles based on the display where mpv is initialized, and automatically changes the color profile when display is changed or the profile itself is changed from System Preferences. @UliZappe was responsible with the testing and implementation of a lot of this commit, including the original implementation of `cocoa_get_icc_profile_path` (See #594). Fixes #594

vo_opengl: gl_lcms: replace icc-cache by icc-cache-dir This now stores caches for multiple ICC profiles, potentially all the user has ever used. The big use case for this is for users with multiple monitors. The old logic would mandate recomputing the LUT and discarding the cache whenever dragging mpv from one screen to another. This also avoids having to save and check the ICC profile itself, since the file name already uniquely determines it.

vo_opengl: generate 3DLUT against source and use full BT.1886 This commit refactors the 3DLUT loading mechanism to build the 3DLUT against the original source characteristics of the file. This allows us, among other things, to use a real BT.1886 profile for the source. This also allows us to actually use perceptual mappings. Finally, this reduces errors on standard gamut displays (where the previous 3DLUT target of BT.2020 was unreasonably wide). This also improves the overall accuracy of the 3DLUT due to eliminating rounding errors where possible, and allows for more accurate use of LUT-based ICC profiles. The current code is somewhat more ugly than necessary, because the idea was to implement this commit in a working state first, and then maybe refactor the profile loading mechanism in a later commit. Fixes #2815.
