It makes sense to do the length checking in the core rather than expect
each driver to deal with it themselves. This puts the onus on the core to
dictate which algorithm/key combinations are valid before calling a driver.
Additionally, this commit also updates the psa_mac_sign_finish function
to better deal with output buffer sanitation, as per the review comments
on #4247.

The purpose of key_set was to guard the operation structure from being
used for update/finish before a key was set. Now that the implementation
fully adheres to the PSA API, that function is covered by the `alg`
variable instead. It's set to the algorithm in use when a key is set, and
is zero when the operation is reset/invalid.

Since HMAC moved into its own compilation unit, the internal API needed
to be documented and finalized. This means no more reaching deep into
the operation structure from within the PSA Crypto core. This will make
future refactoring work easier, since internal HMAC is now opaque to the
core.

This was probably included by mistake, because the file itself is part
of the inclusion chain starting with crypto.h.
Signed-off-by: Steven Cooreman <steven.cooreman@silabs.com>
This is a preparatory step in order to be able to organize the include
chain from crypto_struct in such a way that the MAC operation structure
for the PSA 'software' driver can make use of the hash operation structure.
Conceptually:
* Primitives:
* Hash
* Cipher
* Composites:
* AEAD (can use cipher)
* MAC (can use cipher and/or hash)

Fix an issue where `MBEDTLS_X509_REMOVE_INFO` was defined/enabled by default
in `include/mbedtls/config.h`. This should also fix the `context-info.sh` test
where it ran the default config and expected to see some output from the x509
info functions that were removed.
Also updated relevant comments to more accurately explain how the

The new compile-time option MBEDTLS_X509_REMOVE_INFO removes various
X.509 debugging strings and functionality, including
```
mbedtls_x509_crt_verify_info()
```
which ssl_client2.c and ssl_server2.c use to print human readable
descriptions of X.509 verification failure conditions. Those
conditions are also grepped for in numerous ssl-opt.sh tests.
Instead of disabling those tests if MBEDTLS_X509_REMOVE_INFO is set,
this commit essentially moves mbedtls_x509_crt_verify_info() to
ssl_client2.c and ssl_server2.c. However, instead of just copy-pasting
the code from x509_crt.c, the following approach is used:
A macro MBEDTLS_X509_CRT_ERROR_INFO_LIST is introduced which for each
verification failure condition invokes a user-defined macro X509_CRT_ERROR_INFO
with (a) the numerical error code, (b) the string presentation of the
corresponding error macro, (c) the info string for the error condition.
This macro can thus be used to generate code which somehow iterates over
the verifiation failure conditions, but the list of error conditions and
information strings is nowhere duplicated.
This is then used to re-implement mbedtls_x509_crt_verify_info() in
x509_crt.c and to provide a functionally equivalent (yet slightly different)
version in ssl_client2.c and ssl_server2.c in case MBEDTLS_X509_REMOVE_INFO
is set.
This way, little changes to ssl-opt.sh will be necessary in case
MBEDTLS_X509_REMOVE_INFO is set because the info strings for the
verification failure conditions will be printed regardless of whether
MBEDTLS_X509_REMOVE_INFO is set or not.

Note on naming: previously considered input_numeric but then thought the
other two input function are "input <name>" not "input <adjective>" so
decided to follow that pattern. input_int would be shorter but sounds
too much like the C type, which could be confusing as that's not the
type of the parameter; IMO "integer" avoids that problem.

For the numeric values, I followed the apparent existing convention:
- first byte is 01 for secret inputs, 02 for non-secret inputs
- then second by is just incremented for each new input type
