doc: Generate cross-references in code snippets to the Guile manual.
Occurrences of 'list', 'cons', etc. in code snippets now link to the relevant section of the Guile manual. * doc/build.scm (guile-manual, %guile-manual-base-url) (guile-mono-node-indexes, guile-split-node-indexes): New variables. (for-all-languages, merge-index-alists): New procedures. <top level>: Rename 'mono-node-indexes' and 'split-node-indexes' to 'guix-mono-node-indexes' and 'guix-split-node-indexes' respectively. Add 'mono-node-indexes' and 'split-node-indexes' defined as calls to 'merge-index-alists'.
