[doc] extend.texi: break fixed-point paragraphs into bulleted lists

[Janis Johnson]

The description of the fixed-point C extension is difficult to read
because of a couple of very long paragraphs.  This patch merely breaks
those up into bulleted lists.

Tested with make dvi/info/html; OK for trunk?
