sphinx: fix internal links
Many of the internal links were not converted probably from DocBook
using pandoc. After looking at the various patterns, the follow series
of 'naive' Python regexp were used to perform some additional
automatic conversion.
Also, since we rely on built-in glossary, all links to terms need to
use the sphinx :term: syntax.
This commit is generated using the following Python series of regexp:
line = re.sub("`+(\w+)`* <(\&YOCTO_DOCS_REF_URL;)?#var-\\1>`__",
":term:`\\1`",
line)
line = re.sub("`+do_([a-z_]+)`* <(\&YOCTO_DOCS_REF_URL;)?#ref-tasks-\\1>`__",

It won't catch multiline strings, but it catches a very large number
