[gdi32] Protect some DIB functions from bad inputs (take 6)

[Dan Kegel]

This should fix http://bugs.winehq.org/show_bug.cgi?id=7380

The test is taken from Rein's original patch
http://marc.info/?l=wine-patches&m=114269049431915&w=2
The address checking uses idea from Rein, Louis, and Anastasius,
refactored slightly, and defiantly using IsBadReadPtr.  I bet it's the
right thing to do.  And it's bloody well time.
