win32: remove unused net_strerror()
Avcodec chroma: use a more resistant ifdef for 0BGR
darwin: implement vlc_strerror and vlc_strerror_c

strerror_l will not be available on Darwin anytime soon
darwin/error: there is no need to re-implement the C run-time error array unless the deprecated sys_errlist array is actually removed some day
darwin/error: add partial l10n and doc
Restore ncurses colors on exit

If the terminal colors are not manually restored they will not change
back when vlc exits, causing other applications to use the wrong colors
