Kévin Petit 0702f2ecee Make genrand_int32 thread safe (#1797)
The initialisation code is clearly meant to be run once but the volatile
flag did not guarantee that at all:

- Volatile does not mean atomic and loading the flag vs. other writes
  was not safe.
- Multiple threads could have loaded 0 and performed the initialisation
  resulting in write collisions.

Rely on std::call_once to provide the guarantee.

This issue was flagged by TSAN.
