02969bf882 ChaCha20: allow in-place en/decryption 
All other ciphers so far allow this. In particular, the TLS layer depends on
this, despite what's documented in the Cipher layer, see
https://github.com/ARMmbed/mbedtls/issues/1085
https://github.com/ARMmbed/mbedtls/issues/1087

Also, this can be useful for implementing chachapoly without depending on the
semi-internal function keystream_block(), see next commit.

d4bd8569d4 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.

54b1a7342c Rename poly1305_setkey() to poly1305_starts() 
For consistency with the existing CMAC and HMAC APIs

deda80e80d Adapt the _ALT style to our new standard 
- in .h files: only put the context declaration inside the #ifdef _ALT
  (this was changed in 2.9.0, ie after the original PR)
- in .c file: only leave selftest out of _ALT: even though some function are
  trivial to build from other parts, alt implementors might want to go another
way about them (for efficiency or other reasons)

f28c2aa64e Allow some parameters to be NULL if the length is 0. 
This change permits users of the ChaCha20/Poly1305 algorithms
(and the AEAD construction thereof) to pass NULL pointers for
data that they do not need, and avoids the need to provide a valid
buffer for data that is not used.

31ac12e004 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.

fe0669f52a ecp: Fix binary compatibility with group ID 
We naturally added the new Curve448 ECP group ID in alphabetical order in
the mbedtls_ecp_group_id enum. However, this causes binary incompatibility
issues as previous binaries will use values for groups that now have a
different meaning. For example, MBEDTLS_ECP_DP_SECP192K1, old value 10,
would mean Curve448 (MBEDTLS_ECP_DP_CURVE448) and the wrong group ID used.

Fix the binary compatibility issue by adding new enum entries to the end of
the enum, even though this isn't so great for readbility as the list is no
longer in alphabetical order. However, the list wasn't perfectly in
alphabetical order before anyway.
