qdoc: Teach qdoc to use multiple trees (part 2)

qdoc now knows how to search the forrest of node
trees in an optimal order. But there remain some
problems with specific searches that cross module
boundaries. These include group membership and C++
and QML module membership, as well ass C++ base
class resolution. Part 3 will be concerned with
fixing these remaining bugs.

With this update, qdoc now takes less time to
generate the docs for Qt 5. Testing indicates
that qdoc run time has dropped from about 14
minutes to about 7.5 minutes on an iMac.
