CppLocatorData: Don't use recursive mutex

Browse Source 
Don't use recursive mutex in CppLocatorData class,
as this is more expensive to construct than simple
QMutex. Refactor the code so that every call to
flushPendingDocument() is done with already locked
m_pendingDocumentsMutex. This eliminates the need
for recursive mutex.

Remove unused allIndexItems() method.
