Subject: [PATCH] QHash: constify some QHashNode members
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

They're read-only member variables (key, hash value of the key)
set only in the ctors, or a "comparison" member function.
All of them can be constified.
