Fix length checks in ssl3_get_client_hello().
Use s->s3->in_read_app_data differently to fix ssl3_read_internal().
Changes between 0.9.6c and 0.9.6d [XX xxx XXXX]
+ *) Implement a countermeasure against a vulnerability recently found
+ in CBC ciphersuites in SSL 3.0/TLS 1.0: Send an empty fragment
+ before application data chunks to avoid the use of known IVs
+ with data potentially chosen by the attacker.
+ [Bodo Moeller]
+
+ *) Fix length checks in ssl3_get_client_hello().
+ [Bodo Moeller]
+
+ *) TLS/SSL library bugfix: use s->s3->in_read_app_data differently
+ to prevent ssl3_read_internal() from incorrectly assuming that
+ ssl3_read_bytes() found application data while handshake
+ processing was enabled when in fact s->s3->in_read_app_data was
+ merely automatically cleared during the initial handshake.
+ [Bodo Moeller; problem pointed out by Arne Ansper <arne@ats.cyber.ee>]
+
*) Fix object definitions for Private and Enterprise: they were not
recognized in their shortname (=lowercase) representation. Extend
obj_dat.pl to issue an error when using undefined keywords instead
