Log message:
Provide BN_zero()/BN_one() as functions and make BN_zero() always succeed.
BN_zero() is currently implemented using BN_set_word(), which means it can
fail, however almost nothing ever checks the return value. A long time
ago OpenSSL changed BN_zero() to always succeed and return void, however
kept BN_zero as a macro that calls a new BN_zero_ex() function, so that
it can be switched back to the "can fail" version.
Take a simpler approach - change BN_zero()/BN_one() to functions and make
BN_zero() always succeed. This will be exposed in the next bump, at which
point we can hopefully also remove the BN_zero_ex() function.
