Git commit f2f6539f58926181da71c19daa6ddc9aba7ea617 by Kevin Funk.
Committed on 03/11/2013 at 20:15.
Pushed by kfunk into branch '4.6'.

Don't crash in case of dangling updates

DUChain::waitForUpdate does QApplication::progressEvents() in a while-loop and
waits for an update from the background parser. In case the application
is shut down, CppLanguageSupport eventually is deleted, but the
while-loop may still be running. When the call to
DUChain::waitForUpdate inside
CppLanguageSupport::switchDefinitionDeclaration returns, 'this' is
already invalid and the subsequent call to CppLanguage::standardContext
ends up in SIGSEGV.
Hence, always check if the context returned by waitForUpdate(...) is
valid and return immediately if not.
