Commit 08c337d058 "Remove useless parameter from function" removed the
parameter mode from the functions mbedtls_aria_crypt_ecb() which broke their
respective test suite.
This commit fixes those test cases.
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.

When MBEDTLS_TIMING_C was not defined in config.h, but the MemSan
memory sanitizer was activated, entropy_poll.c used memset without
declaring it. Fix this by including string.h unconditionally.
As a protection against the Lucky Thirteen attack, the TLS code for
CBC decryption in encrypt-then-MAC mode performs extra MAC
calculations to compensate for variations in message size due to
padding. The amount of extra MAC calculation to perform was based on
the assumption that the bulk of the time is spent in processing
64-byte blocks, which is correct for most supported hashes but not for
SHA-384. Correct the amount of extra work for SHA-384 (and SHA-512
which is currently not used in TLS, and MD2 although no one should
care about that).
Fix IAR compiler warnings
Two warnings have been fixed:
1. code 'if( len <= 0xFFFFFFFF )' gave warning 'pointless integer comparison'.
This was fixed by wraping the condition in '#if SIZE_MAX > 0xFFFFFFFF'.
2. code 'diff |= A[i] ^ B[i];' gave warning 'the order of volatile accesses is undefined in'.
This was fixed by read the volatile data in temporary variables before the computation.

Consistent use of CMAKE_C_COMPILER_ID
The cast to void was motivated by the assumption that the functions only
return non-zero when passed bad arguments, but that might not be true of
alternative implementation, for example on hardware failure.
- 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.
