8d200744b4 Clarify the ChaCha20-Poly1305 assembly functions' final parameters.
The memcpy of a pointer looks like a typo, though it isn't. Instead,
transcribe what the functions expect into a union and let C fill it in.

abbf365b6d Make the bssl::SealRecord out_suffix arg fixed length.
Similarly, add EVP_AEAD_CTX_tag_len which computes the exact tag length
for required by EVP_AEAD_CTX_seal_scatter.

c66e397106 Enable extra_in with the ChaCha20-Poly1305 AEAD.
This change updates the ChaCha20-Poly1305 AEAD to be able to process
|extra_in| data. It does this by encrypting the extra data byte-by-byte
(because extra data should be very small). Both the generic and assembly
code is updated to be able to include this extra ciphertext in the
Poly1305 calculation.

18d9f28f0d Add EVP_AEAD_CTX_{seal_scatter,open_gather}.
These behave like EVP_AEAD_CTX_{seal,open} respectively, but receive
ciphertext and authentication tag as separate arguments, rather than one
contiguous out or in buffer.
