Simplify all the cipher gathering logic. The set of supported ciphers is known,
so there is no need to determine if some cipher exists but doesn't work.

Update SSL_OP_ALL to account for SSL_OP_CRYPTOPRO_TLSEXT_BUG being gone,
and update ssl3_setup_write_buffer to account for SSL_MODE_CBC_RECORD_SPLITTING
rather than the now defunct SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS.
Also remove SSL_OP_TLS_BLOCK_PADDING_BUG. This is to allow for a buggy peer
which pads CBC with N bytes of value N rather than N+1 bytes of value N. This
quirk has been broken since CBC padding checks became constant-time, as
demonstrated by this attempt at a test. (Instead of just decrementing
padding_length, it needs to also keep track of a separate padding_value and not
decrement that one.)

(The quirk would also fall over anyway if the buggy client ever did a session
resumption; then the server speaks first rather than the client, and the quirk
triggered on reading the first encrypted record from the peer.)

09bd58d1f1 flipped a condition. Doing that
memset in the DTLS case breaks retransmits across a CCS and fails to memset in
the TLS case.
Strangely, it didn't break any tests, but I think that's a function of us
lacking renego tests. The sequence number doesn't seem to be used in the
initial handshake for TLS, so it stayed at zero. After a renego, that codepath
is relevant.

NULL, SRP, CAMELLIA, export ciphers, SSLv2, IDEA, and SEED are gone. Unknown
directives are silently ignored in the parser, so there is no need to retain
their masks and entries in the cipher suite aliases.

comment next to it. It's not actually related to GOST (dates to OpenSSL initial
commit), but isn't especially helpful at this point.

This change adds the infrastructure to use stateful AEADs in ssl/ and
specifically wires in the stitched, RC4-MD5 AEAD. Over time, all
cipher suites will be supported via the AEAD interface and the old
EVP_CIPHER code will die off.

Since all AEAD ciphers now go through EVP_AEAD interface, the code which
uses EVP_Cipher interface no longer needs any of AEAD handling logic.
This also removes EVP_CTRL_AEAD_TLS1_AAD from GCM interface, which was
duplicating non-TLS-specific GCM logic and is not used anymore.

This patch removes support for empty records (which is almost
universally disabled via SSL_OP_ALL) and adds optional support for 1/n-1
record splitting.
The latter is not enabled by default, since it's not typically used on
servers, but it should be enabled in web browsers since there are known
attacks in that case (see BEAST).
Initial fork from f2d678e6e89b6508147086610e985d4e8416e867 (1.0.2 beta).
(This change contains substantial changes from the original and
effectively starts a new history.)
