6e20f55646 Fix d2i_SSL_SESSION for DTLS1_BAD_VER
Some Cisco appliances use a pre-standard version number for DTLS. We support
this as DTLS1_BAD_VER within the code.

This change fixes d2i_SSL_SESSION for that DTLS version.

Based on an original patch by David Woodhouse <dwmw2@infradead.org>

05e769f269 Remove instances in libssl of the constant 28 (for size of IPv4 header + UDP)
and instead use the value provided by the underlying BIO. Also provide some
new DTLS_CTRLs so that the library user can set the mtu without needing to
know this constant. These new DTLS_CTRLs provide the capability to set the
link level mtu to be used (i.e. including this IP/UDP overhead). The previous
DTLS_CTRLs required the library user to subtract this overhead first.

e5f261df73 Ensure SSL3_FLAGS_CCS_OK (or d1->change_cipher_spec_ok for DTLS) is reset
once the ChangeCipherSpec message is received. Previously, the server would
set the flag once at SSL3_ST_SR_CERT_VRFY and again at SSL3_ST_SR_FINISHED.
This would allow a second CCS to arrive and would corrupt the server state.

(Because the first CCS would latch the correct keys and subsequent CCS
messages would have to be encrypted, a MitM attacker cannot exploit this,
though.)

Thanks to Joeri de Ruiter for reporting this issue.

65a87d3cc3 Dual DTLS version methods.
Add new methods DTLS_*_method() which support both DTLS 1.0 and DTLS 1.2 and
pick the highest version the peer supports during negotiation.

As with SSL/TLS options can change this behaviour specifically
SSL_OP_NO_DTLSv1 and SSL_OP_NO_DTLSv1_2.

acec5a6244 Provisional DTLS 1.2 support.
Add correct flags for DTLS 1.2, update s_server and s_client to handle

Currently no support for version negotiation: i.e. if client/server selects
DTLS 1.2 it is that or nothing.

74096890ba Initial "opaque SSL" framework. If an application defines OPENSSL_NO_SSL_INTERN
all ssl related structures are opaque and internals cannot be directly
accessed. Many applications will need some modification to support this and
most likely some additional functions added to OpenSSL.

The advantage of this option is that any application supporting it will still
be binary compatible if SSL structures change.

188b05792f pqueue and dtls uses 64-bit values. Unfortunately, OpenSSL doesn't
have a uniform representation for those over all architectures, so a
little bit of hackery is needed.

6c61726b2a Lots of Win32 fixes for DTLS.
1. "unsigned long long" isn't portable changed: to BN_ULLONG.
2. The LL prefix isn't allowed in VC++ but it isn't needed where it is used.
2. Avoid lots of compiler warnings about signed/unsigned mismatches.
3. Include new library directory pqueue in mk1mf build system.
4. Update symbols.
