sphinx: add links to terms in the BitBake glossary

Using the intersphinx extension, we can refer to terms in the Bitbake
manual using :term:`bitbake:FOO`. This patch implements that, mostly
using the following regexp:

  line = re.sub("`+(\w+)`* <(\&YOCTO_DOCS_BB_URL;)?#var(-bb)?-\\1>`__",
                ":term:`bitbake:\\1`",
                line)

And a handful of manual fixup.
