Qiang Yu e5041ef036 docs,src: replace doc and comments for PIPE_CAP with pipe_caps 
Use command:
  find . -type d \( -path "./.git" -o -path "./docs/relnotes" \) -prune -o -type f -exec sed -i 's/PIPE_CAP_\([A-Za-z0-9_]*\)/pipe_caps.\L\1/g' {} +
  find . -type d \( -path "./.git" -o -path "./docs/relnotes" \) -prune -o -type f -exec sed -i 's/PIPE_CAPF_\([A-Za-z0-9_]*\)/pipe_caps.\L\1/g' {} +

With manual adjustment for docs/gallium/screen.rst to merge
pipe_cap and pipe_capf section.
