This reverts commit 7aa24116.
It breaks the code model updates completely. So reverting this change
until we have the right thing.

Add state logic to CppCodeModelManagerInterface, making it aware whether
an indexer is running, protect the update methods from another
invocation while running. Add changed signals to IVersionControl and
VCSManager and wire them to the update methods. Add a menu action for
manually updating.

updateModifiedFiles ckecks the timestamp and reparses all the modified files in the current snapshot.

Ensure the user can stop a semantic search and added a method to get a pointer to the ModelManagerInterface.

Use QFileInfo::fileName() to get the filename, since that also works
when the original path wasn't canonical.

In order to speed up completion for include statements.

Make debugger tooltip API more general, have the engines check the
correct file type, figure out the expression and context from the text
editor.

Put common functionality in watchutils.cpp. In the CDB engine, check
whether a tooltip expression is a known variable within the stack frame
context. If so, retrieve via symbol group or dumpers. Cache by function
and expression.

This adds a way for plugins to tell the cppmodel that for certain files,
the actual contents come from it, instead of reading from the disk.
(For texteditors the cppmodel does that automatically.)

replace ExtensionSystem::PluginManager::instance()->getObject<Core::ICore>() by Core::ICore::instance()

This change removes a number of wrong usages of the CppModelManager::documents()/document().
