Thanks to Lennart Beringer for pointing that that malloc failures could
lead to invalid EVP_MD_CTX states. This change cleans up the code in
general so that fallible operations are all performed before mutating
objects. Thus failures should leave objects in a valid state.
Also, |ctx_size| is never zero and a hash with no context is not
sensible, so stop handling that case and simply assert that it doesn't
occur.

Add a simple dumb webserver that responds with the session status for
any GET request. This option is intended to be used with -loop to
generate automated responses to requests and serves two purposes: (1)
test that application data from clients can be decrypted, (2) test that
clients can decrypt data from the server and (3) early data indicator.

Newer versions of LLVM can emit this instruction. Note that there are
two different Intel instructions, both called “movsd”. The old one is an

The Java client implementation of the 3SHAKE mitigation incorrectly
rejects initial handshakes when all of the following are true:
1. The ClientHello offered a session.
2. The session was successfully resumed previously.
3. The server declines the session.
4. The server sends a certificate with a different SAN list than in the
previous session.
(Note the 3SHAKE mitigation is to reject certificates changes on
renegotiation, while Java's logic applies to initial handshakes as
well.)
The end result is long-lived Java clients break on some certificate
rotations. Fingerprint Java clients and decline all offered sessions.
This avoids (2) while still introducing new sessions to clear any
existing problematic sessions.

This guards against the name constraints check consuming large amounts
of CPU time when certificates in the presented chain contain an
excessive number of names (specifically subject email names or subject
alternative DNS names) and/or name constraints.
Name constraints checking compares the names presented in a certificate
against the name constraints included in a certificate higher up in the
chain using two nested for loops.
Move the name constraints check so that it happens after signature
verification so peers cannot exploit this using a chain with invalid
signatures. Also impose a hard limit on the number of name constraints
check loop iterations to further mitigate the issue.
Thanks to NCC for finding this issue.

Putting it on SSL_HANDSHAKE would be better, but sadly a number of
