Introduce an RCU lock implementation as an alternative locking mechanism to openssl. The api is documented in the ossl_rcu.pod file Read side implementaiton is comparable to that of RWLOCKS: ossl_rcu_read_lock(lock); < critical section in which data can be accessed via ossl_derefrence > ossl_rcu_read_unlock(lock); Write side implementation is: ossl_rcu_write_lock(lock); < critical section in which data can be updated via ossl_assign_pointer and stale data can optionally be scheduled for removal via ossl_rcu_call > ossl_rcu_write_unlock(lock); ... ossl_synchronize_rcu(lock); ossl_rcu_call fixup Reviewed-by: Hugo Landau <hlandau@openssl.org> Reviewed-by: Matt Caswell <matt@openssl.org> (Merged from https://github.com/openssl/openssl/pull/22729)
