modernizing html output

[Per Bothner]

See this old thread: 
https://lists.gnu.org/archive/html/bug-texinfo/2016-02/msg00056.html

Attached is a simple patch to generate better-structured html.

It wraps all nodes (anything processed by _convert_heading_command) in a <div> 
block.
It uses id="xx" instead of <a name="xx">.  When I could, I attached the id to 
existing
elements (or the new <div> block); otherwise I replaced the <a> by a <span>.

If people are concerned about breaking things, I suggested adding --html4 and 
--html5
as new output options.  Only --html5 would create the new-style output.
The existing --html flag would be an alias to --html4.  After a release or two 
we could
change the default so --html is a default for --html5.
