QHash: double the size of the stored seed
There's now another half of the seed which will be used by the hashers.
This is not stored in QHash, so it is never changed for the lifetime of
the application (not even when QHashSeed::setDeterministicGlobalSeed()
is called). However, we will not use it when we're in deterministic
mode.
This commit uses the compiler thread-safe statics to implement the
initialization of more than one atomic word, thus freeing us from having
to have a reserved value. As a bonus, the QT_HASH_SEED warning will only
be printed once.
