Conflicts:
* configs/config-psa-crypto.h: modified here, removed in development
* tests/suites/test_suite_x509parse.data: all conflicts are in depends_on
lines where development made a change unrelated to MBEDTLS_SHAxxx and our
branch either changed `MBEDTLS_SHA256_C` to `MBEDTLS_SHA224_C` or
`MBEDTLS_SHA512_C:!MBEDTLS_SHA512_NO_SHA384` to ``MBEDTLS_SHA384_C`, with
no change to what the test does. Pick the other branch's dependency
changes then apply our SHA dpeendency change.
To simplify the documentation, and because there are only two realistic
behaviors in practice, only allow two behaviors for multipart output:
immediate output, or buffering of the last partial block.
State some simple rules that applications can follow if they don't care about
the details.
Explicitly state how much output is needed for finish(). Only require the
buffer size to be the size of the actual output, not the size of the potential
output in the worst case. Rename the parameter from output_len to output_size
since it's a buffer size and not necessarily the length of the data.
No longer guarantee that the built-in implementation produces immediate
output.

Add (internal only) define to config.h which allows the temporary
implementation of CCM to work, by removing the buffer zeroization on tag
fail when decrypting. This will obviously be removed when multipart CCM
is properaly implemented
Signed-off-by: Paul Elliott <paul.elliott@arm.com>
Move CCM to update all data at update step, as final step can only
output at most a block length, so outputting all data at this step
significantly breaks the tests. Had to add unpleasant workaround for the
validate stage, but this is the only way I can do things without
breaking CCM Alt implementations.
Signed-off-by: Paul Elliott <paul.elliott@arm.com>
For the time being CCM and GCM are not entirely implemented correctly
due to issues with their underlying implentations, which would be
difficult to fix in 2.x, and thus require all the AD and data to be
passed in in one go.

mbedtls_ssl_{get,set}_session() exhibited idempotent behaviour
in Mbed TLS 2.x. Multiple calls to those functions are not useful
in TLS 1.2, and the idempotent nature is unsuitable for support of
TLS 1.3 which introduces the availabilty to offer multiple tickets
for resumption, as well as receive multiple tickets.
In preparation for TLS 1.3 support, this commit relaxes the semantics
of `mbedtls_ssl_{get,set}_session()` by allowing implementations to
fail gracefully, and leveraging this freedom by modifying the
existing TLS 1.2 implementation to only accept one call to
`mbedtls_ssl_{get,set}_session()` per context, and non-fatally
failing all subsequent invocations.
For TLS 1.3, it will be leveraged by making multiple calls to
`mbedtls_ssl_get_session()` issue one ticket a time until no more
tickets are available, and by using multiple calls to
`mbedtls_ssl_set_session()` to allow the client to offer multiple
tickets to the server.

The output parameter of mbedtls_sha256_finish_ret and mbedtls_sha256_ret
now has a pointer type rather than array type. This removes spurious
warnings in some compilers when outputting a SHA-224 hash into a
28-byte buffer.
