libcouchbase 2.10.6 doesn't compile anymore on CentOS6

In 2.10.6 the std:random_shuffle() has been replaced by std::random_device() and std::shuffle(). These are not supported by gcc 4.4.7. (random_device is available by enabling experimental extensions via -std=gnu++0x, but than still shuffle() is missing).

The following commits cause this:
