cpp plugin: visitor & context madness

[Alexandre Courbot]

Just to add a couple of oddities to your list: it also seems like
AbstractTypeBuilder and AbstractDeclarationBuilder are actually never
used in either KDevplatform or KDevelop, despite being said to be the
basic blocks of DUChain construction in the documentation
(http://api.kde.org/extragear-api/kdevelop-apidocs/kdevplatform/language/duchain/html/duchain-design.html
). At least that's what a 'git grep' in both repositories seem to
indicate.

I am currently trying to understand how DUChains are constructed in
order to implement C99 initializations and noticed that. Guess if
either of us have time to update the documentation a little bit, this
could also be helpful.
