DRBG: add locking api
This commit adds three new accessors to the internal DRBG lock
int RAND_DRBG_lock(RAND_DRBG *drbg)
int RAND_DRBG_unlock(RAND_DRBG *drbg)
int RAND_DRBG_enable_locking(RAND_DRBG *drbg)
The three shared DRBGs are intended to be used concurrently, so they
have locking enabled by default. It is the callers responsibility to
guard access to the shared DRBGs by calls to RAND_DRBG_lock() and
RAND_DRBG_unlock().
All other DRBG instances don't have locking enabled by default, because
they are intendended to be used by a single thread. If it is desired,
locking can be enabled by using RAND_DRBG_enable_locking().
