A bit of headers cleanup
* Headers in include must contain the structures and prototypes needed by the plugins and should be named vlc_*. * Headers in include/vlc must contain the structures and prototypes needed by external libvlc clients * Moved and renamed some things in headers. - Removed vlc_cpu.h, vlc_error.h (merged in vlc_common) - Removed snapshot.h (merged in vlc_vout.h) - Removed vlc_spu.h (merged in vlc_osd.h) - Removed intf_eject.h and vlc_interaction.h (merged in vlc_interface) - Moved all internal headers to src - Merged vlc_video.h and video_output.h and move private things to src - Removed vlc/intf.h, vlc/aout.h, vlc/vout.h, vlc/decoder.h and vlc/input.h (meta headers for use in modules, and often implying too large dependencies) * Removed some useless dependencies * Unexported a bunch of functions and structures used only in src/ (--> Still some work here) * Finally made input_thread_t and input_source_t (mostly) private. Added input_GetItem to fetch the input_item of an input_thread * Cleaned up deprecated entries in vlc_symbols.h and bumped up symbol prefix This commit has a 99% probability of breaking the build, 0.1% of killing your cat and 0% of getting you hot chicks.
