Subject: QDuplicateTracker: accept the number of elements to reserve as a ctor
 argument
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This prevents us from first reserve()ing Prealloc elements, and then
possibly reserve()ing a larger number, which leaves the first bucket
list's memory unused.

Consequently, deprecate reserve().
