auto-chaining feature eventually. Given that, SSL_CTX_set_cert_store

The split was only needed for buffering records. Likewise, the extra
seq_num field is now unnecessary.
This also fixes a bug where dtls1_process_record will push an error on
the queue if the decrypted record is too large, which dtls1_get_record
will ignore but fail to clear, leaving garbage on the error queue. The
error is now treated as fatal; the reason DTLS silently drops invalid
packets is worrying about ease of DoS, but after SSL_AEAD_CTX_open, the
packet has been authenticated. (Unless it's the null cipher, but that's
during the handshake and the handshake is already DoS-able by breaking
handshake reassembly state.)
The function is still rather a mess. Later changes will clean this up.

In the ancient times, before ex_data and OpenSSL, SSLeay supported a
single app_data slot in various types. Later app_data begat ex_data, and
app_data was replaced by compatibility macros to ex_data index zero.
Today, app_data is still in use, but ex_data never reserved index zero
for app_data. This causes some danger where, if the first ex_data
registration did not use NULL callbacks, the registration's callbacks
would collide with app_data.
Instead, add an option to the types with app_data to reserve index zero.
Also switch SSL_get_ex_data_X509_STORE_CTX_idx to always return zero
rather than allocate a new one. It used to be that you used
X509_STORE_CTX_get_app_data. I only found one consumer that we probably
don't care about, but, to be safe and since it's easy, go with the
conservative option. (Although SSL_get_ex_data_X509_STORE_CTX_idx wasn't
guaranteed to alias app_data, in practice it always did. No consumer
ever calls X509_STORE_CTX_get_ex_new_index.)
