Fix build with latest Apple clang version 

Building with Apple clang 13.1.6.13160021 (from command line tools 13.3)
results in

qhash.cpp:754:39: error: passing 16-byte aligned argument to 32-byte
aligned parameter 3 of 'operator()' may result in an unaligned pointer
access [-Werror,-Walign-mismatch]

        hash2x32bytes(state0, state1, src, src + 1);
                                      ^

Help the compiler with deducing the right type for 'src' and 'srcend'.
Also makes 'src' const explicitly.
