Fix from main trunk, 2000-09-26 13:30 bodo:

Don't modify s->read_ahead in SSL_clear, which is called from
accept/connect functions; those should not change the read_ahead
setting of the SSL structure.

Fix from main trunk, 2000-09-26 13:38  bodo:

Set s->read_ahead in SSL_new because SSL_clear no longer modifies it.
