Giuseppe D'Angelo 9a77171ccc QHash security fix (1.5/2): qHash two arguments overload support 
Algorithmic complexity attacks against hash tables have been known
since 2003 (cf. [1, 2]), and they have been left unpatched for years
until the 2011 attacks [3] against many libraries /
(reference) implementations of programming languages.

This patch adds a qHash overload taking two arguments: the value to
be hashed, and a uint to be used as a seed for the hash function
itself (support the global QHash seed was added in a previous patch).
The seed itself is not used just yet; instead, 0 is passed.

Compatibility with the one-argument qHash(T) implementation is kept
through a catch-all template.
