QFutureInterface: wrap a pair of {release,reserve}Thread() calls with RAII
Rationale: a wait on a condition-variable is usually a cancellation point. On Posix, and probably in C++ at some point, a thread cancellation is done by (a kind of) exception unwinding the stack. To ensure that we call reserveThread() in all cases, wrap the function pair in a RAII class. Even if we currently don't seem to support exceptions in QtCore, this is low-hanging fruit, and no worse than what we had before.
