Implement AEAD-ChaCha20-Poly1305. This implementation is based off the description in RFC 7539. The ChaCha20 code is also updated to provide a means of generating keystream blocks with arbitrary counter values. This is used to generated the one-time Poly1305 key in the AEAD construction.

/* BEGIN_HEADER */
Rename aead_chacha20_poly1305 to chachapoly While the old name is explicit and aligned with the RFC, it's also very long, so with the mbedtls_ prefix prepended we get a 31-char prefix to each identifier, which quickly conflicts with our 80-column policy. The new name is shorter, it's what a lot of people use when speaking about that construction anyway, and hopefully should not introduce confusion at it seems unlikely that variants other than 20/1305 be standardised in the foreseeable future.

Implement AEAD-ChaCha20-Poly1305. This implementation is based off the description in RFC 7539. The ChaCha20 code is also updated to provide a means of generating keystream blocks with arbitrary counter values. This is used to generated the one-time Poly1305 key in the AEAD construction.

Rename aead_chacha20_poly1305 to chachapoly While the old name is explicit and aligned with the RFC, it's also very long, so with the mbedtls_ prefix prepended we get a 31-char prefix to each identifier, which quickly conflicts with our 80-column policy. The new name is shorter, it's what a lot of people use when speaking about that construction anyway, and hopefully should not introduce confusion at it seems unlikely that variants other than 20/1305 be standardised in the foreseeable future.
