  x86: vc1: call ff_vc1dsp_init_x86() under if (ARCH_X86)
  x86: cavs: call ff_cavsdsp_init_x86() under if (ARCH_X86)
  x86: call most of the x86 dsp init functions under if (ARCH_X86)
  doc: support the new website layout
  doc: remove a warning from filters.texi
  doc: initial nut documentation
  segment: drop global headers setting
  lavu: fix typo in Makefile
