Thiago Macieira 7b7c37ab94 Add a benchmark test for QCryptographicHash 
Some quick benchmarks against GNU coreutils 8.21 and OpenSSL 1.0.1e
(time in µs; time for coreutils and OpenSSL include the loading of the
executable):

The numbers for Qt are pretty stable and vary very little; the numbers
for the other two vary quite a bit, since they involve launching and
executing separate processes. We can take the lesson that we're in the
same ballpark for SHA-1 and we should investigate whether our SHA2
implementation is sufficiently optimized.
