Make sure that CMP0012 is set to NEW, without which FindPython3 and
FindPython2 functionality becomes broken with CMake 3.18.2 if searching
by location. CMP0012 being set to OLD is also deprecated as of 3.18.3.
Ensure CMP0011 is set to NEW to avoid warnings and deprecated behaviour
being issued about policy push / pop with CMake 3.18.0 or newer.

Due to a misplaced #endif, the (non-functional) macro definitions were
not properly removed from crypto_compat.h if MBEDTLS_DEPRECATED_REMOVED
was declared.

`finish_sha384_t` was made more generic by using `unsigned char*`
instead of `unsigned char[48]` as the second parameter.
This change tries to make the function casting more robust against
future improvements of gcc analysis.

This commit fixes the same warning fixed by baeedbf9, but without
wasting RAM. By casting `mbedtls_sha512_finish_ret()`, `padbuf`
could be kept 48 bytes long without triggering any warnings.
Signed-off-by: Rodrigo Dias Correa <rodrigo@correas.us>
GCC 11 generated a warning because `padbuf` was too small to be
used as an argument for `mbedtls_sha512_finish_ret`. The `output`
parameter of `mbedtls_sha512_finish_ret` has the type
`unsigned char[64]`, but `padbuf` was only 48 bytes long.
Even though `ssl_calc_finished_tls_sha384` uses only 48 bytes for
the hash output, the size of `padbuf` was increased to 64 bytes.

GCC 11 generated the warnings because the parameter `ret_buf`
was declared as `const char[10]`, but some of the arguments
provided in `run_test_snprintf` are shorter literals, like "".
Now the type of `ret_buf` is `const char *`.
Both implementations of `test_snprintf` were fixed.

In GCC 11, parameters declared as arrays in function prototypes
cannot be declared as pointers in the function definition. The
same is true for the other way around.
The definition of `mbedtls_aes_cmac_prf_128` was changed to match
its public prototype in `cmac.h`. The type `output` was
`unsigned char *`, now is `unsigned char [16]`.
In `ssl_tls.c`, all the `ssl_calc_verify_*` variants now use pointers
for the output `hash` parameter. The array parameters were removed
because those functions must be compatible with the function pointer
`calc_verify` (defined in `ssl_internal.h`).

Rework the section describing key import, in particular to clarify key
size determination and checking. There is no intended semantic change.
Note an open question around support for implementation-specific
import formats.

After a call to psa_get_key_attributes() to retrieve
the attributes of a key into a psa_key_attributes_t
structure, a call to psa_reset_key_attributes() is
mandated to free the resources that may be
referenced by the psa_key_attributes_t structure.
Not calling psa_reset_key_attributes() may result in
a memory leak.
When a test function calls psa_get_key_parameters()
the associated key attributes are systematically
reset in the clean-up part of the function with a
comment to emphasize the need for the reset and make
it more visible.

Rename functions to get a key slot:
. to make their naming more consistent
. to emphasize that those functions set a lock on the
key slot they return to protect it from being wiped
out and re-used while some part of the library
is accessing it.

Move the return of the identifier of a created key from
psa_start_key_creation() to psa_finish_key_creation().
That way in case of creation error, it is less likely to
return the identifier that was temporarily assigned to
the key while trying to create it.

Decrement the slot access count in psa_finish_key_creation()
when the finalization succeeds instead of in functions calling
psa_finish_key_creation(). That way the decrementation cannot
be forgotten and it reduces the code size.

Special handling of volatile key identifiers is not
needed eventually, they can be handled just as
key identifier in the vendor range.
Signed-off-by: Ronald Cron <ronald.cron@arm.com>
In case of a volatile key identifier, no need to check first
the validity of the key identifier, a volatile key identifier
is valid.
Move to a forward search for non-volatile key identifiers as
now key slots with small index are allocated first by
psa_get_empty_key_slot().
