Hanno Becker ae2ff02ff1 Add tests for ChaChaPoly parameter validation
Parameter validation was previously performed and tested unconditionally
for the ChaCha/Poly modules. This commit therefore only needs go guard the
existing tests accordingly and use the appropriate test macros for parameter
validation.

Manuel Pégourié-Gonnard 3dc62a0a9b chachapoly: force correct mode for integrated API
Allowing DECRYPT with crypt_and_tag is a risk as people might fail to check
the tag correctly (or at all). So force them to use auth_decrypt() instead.

Manuel Pégourié-Gonnard 3798b6be6b Add some error codes and merge others
- need HW failure codes too
- re-use relevant poly codes for chachapoly to save on limited space

Values were chosen to leave 3 free slots at the end of the NET odd range.

Manuel Pégourié-Gonnard 59d2c30eba chachapoly: add test for parameter validation
Also fix two bugs found by the new tests.

Also remove redundant test case dependency declarations while at it.

Manuel Pégourié-Gonnard 346b8d5050 chachapoly: split crypt_and_mac() to match GCM API
In addition to making the APIs of the various AEAD modules more consistent
with each other, it's useful to have an auth_decrypt() function so that we can
safely check the tag ourselves, as the user might otherwise do it in an
insecure way (or even forget to do it altogether).

Manuel Pégourié-Gonnard dca3a5d884 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.
