This patch adds libplacebo package that is used
by mpv player.
libplacebo is the core rendering algorithms and
ideas of mpv rewritten as an independent library
and contains a large assortment of video processing
shaders, focusing on both quality and performance.

+Subject: [PATCH] meson.build: add libatomic dependency if needed  
+
+This PR fixes the problem related to not finding the libatomic during the
+build. Some combinations or architecture and libc (e.g. uClibc on SPARC)
+operations in a separate library and don't link with it automatically.
+An optional find_library to meson.build has been added to 
+discover this.
+
+
+Fixes:

+This PR adds the static_assert macro defination for uClibc that is
+missed in some platforms. However, it is limited to C versions lower
