MBEDTLS_CIPHER_ENCRYPT_ONLY is an internal configuration which is
automatically enabled via the PSA. Typically,
once MBEDTLS_CIPHER_ENCRYPT_ONLY is enabled,
MBEDTLS_PSA_CRYPTO_CONFIG must be enabled. This check is only used
to prevent user explicitly enabling MBEDTLS_CIPHER_ENCRYPT_ONLY.
In addition, we shouldn't enable MBEDTLS_CIPHER_ENCRYPT_ONLY if
either CIPHER_MODE_CBC, CIPHER_MODE_XTS or NIST_KW_C is enabled.
Since three of them always need AES-decrypt.

There is no need to set decrypt key under CIPHER_ENCRYPT_ONLY,
so we can remove *setkey_dec_func from ctx to save extra code size.

Some cipher modes use cipher-encrypt to encrypt and decrypt.
(E.g: ECB, CBC). This commit adds support to automatically
enable CIPHER_ENCRYPT_ONLY by PSA when requested cipher modes don't
need cipher_decrypt.

On the advice of travis support, try regenerating the coverity scan
token to see if that fixes the connection to coverity scan

Conflicts:
* `include/psa/crypto_sizes.h`: the addition of the `u` suffix in this branch
conflicts with the rework of the calculation of `PSA_HASH_MAX_SIZE` and
`PSA_HMAC_MAX_HASH_BLOCK_SIZE` in `development`. Use the new definitions
from `development`, and add the `u` suffix to the relevant constants.
We shouldn't violate the requirement that the key identifier can be
reused. In practice, a key manager may destroy a key that's in use by
another process, and the privileged world containing the key manager and
the crypto service should not be perturbed by an unprivileged process.
With respect to blocking, again, a key manager should not be blocked
indefinitely by an unprivileged application.
These are desirable properties even in the short term.

Remove unnecessary "../library" prefix from test suite includes. This
makes the tests repo-agnostic between the mbedtls and psa-crypto repos.
