When creating a split manual with one-node-per-page, the main index.html
ends up getting clobbered by the page for the index() function because
it uses "@node index" which, for html, also creates an index.html page.
To remedy this, add "Function " to every function node so now we output
"Function-index.html" and avoid clobbering. It also namespaces every
other function and helps make sure we don't clobber anything else.
Otherwise, there isn't really much rendering difference as @node text
is mostly internal. Node title text comes from @section instead.
We have "Iconv" and "iconv" nodes which generates Iconv.html and
iconv.html files. On a case-insensitive filesystem, these collide.
Rename the "Iconv" node to match the chapter name that it's already
using to avoid the issue.
This doesn't migrate all the docs, just the libc's manual (pdf/info).
This is to show the basic form of migrating the chew files.
For subdirs that didn't have any docs, I've stripped their settings
for clarity. If someone wanted to suddenly add docs, they can add
the corresponding Makefile.inc files easily.
