a651e6f762 Tidy up grouped MBEDTLS_BYTE_x macros
exchange groups of the byte reading macros with MBEDTLS_PUT_UINTxyz
and then shift the pointer afterwards. Easier to read as you can
see how big the data is that you are putting in, and in the case of
UINT32 AND UINT64 it saves some vertical space.

ad1115a3fd Use byte reading macros in places not using a byte mask
byte shifting opertations throughout library/ were only replaced with
the byte reading macros when an 0xff mask was being used.
The byte reading macros are now more widley used, however they have not
been used in all cases of a byte shift operation, as it detracted from
the immediate readability or otherwise did not seem appropriate.

c045dc14b0 Replace MBEDTLS_CHAR_x with MBEDTLS_BYTE_x
The CHAR macros casted to an unsigned char which in this project
is garunteed to be 8 bits - the same as uint8_t (which BYTE casts
to) therefore, instances of CHAR have been swapped with BYTE and
the number of macros have been cut down

d2d59379ed Remove dead code under MBEDTLS_SHA512_NO_SHA384
TLS code specific to SHA-384 was gated on MBEDTLS_SHA512_C. But SHA-384 also
requires that MBEDTLS_SHA512_NO_SHA384 is not defined. This lead to dead
code in TLS when MBEDTLS_SHA512_C and MBEDTLS_SHA512_NO_SHA384 were both
defined (i.e. when SHA-512 was enabled but not SHA-384).

d48d5c6615 Fix size_t and longlong specifiers for MinGW
MinGW and older windows compilers cannot cope with %zu or %lld (there is
a workaround for MinGW, but it involves linking more code, there is no
workaround for Windows compilers prior to 2013). Attempt to work around
this by defining printf specifiers for size_t per platform for the
compilers that cannot use the C99 specifiers.

f06a6144e2 Change function casting in ssl_calc_finished_tls_sha384
`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`

eb5d014d8e Fix GCC warning in ssl_calc_finished_tls_sha384
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.

2c424570e2 Fix mismatched function parameters (prototype/definition)
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`).

cf56a0a320 psa: Move from key handle to key identifier
Move all the PSA crypto APIs using key handles
to use key identifiers but psa_key_open() and
psa_key_close(). This is done without modifying
any test as key handles and key identifiers are
now the same.

Update the library modules using PSA crypto APIs
to get rid of key handles.

Programs and unit tests are updated to not use
key handles in subsequent commits, not in this
one.
