63eb28c728 Use separate counters for 8-fold and single multiplication steps 
Compilers are likely to generate shorter assembly for loops of the
form `while( cnt-- ) { ... }` rather than
`for( ; count >= X; count -= X ) { ... }`. (E.g. the latter needs
a subtract+compare+branch after each loop, while the former only
needs decrement+branch).

8315811ea7 Remove restrictive proto ver negotiation checks 
Overly restrictive protocol version negotiation checks might be
"version intolerant".  TLS 1.3 and DTLS 1.3 move the version to
the "supported_versions" ClientHello extension.

Note: existing application use which accesses the struct member
(using MBEDTLS_PRIVATE) is not compatible, as the struct is now smaller.

2dfcea2b9d mbedtls_ssl_config min_tls_version, max_tls_version 
Store the TLS version in tls_version instead of major, minor version num

Note: existing application use which accesses the struct member
(using MBEDTLS_PRIVATE) is not compatible on little-endian platforms,
but is compatible on big-endian platforms.  For systems supporting
only TLSv1.2, the underlying values are the same (=> 3).

New setter functions are more type-safe,
taking argument as enum mbedtls_ssl_protocol_version:
mbedtls_ssl_conf_max_tls_version()
mbedtls_ssl_conf_min_tls_version()

da7851c825 Rename mbedtls_ssl_session minor_ver to tls_version 
Store the TLS version instead of minor version number in tls_version.

Note: struct member size changed from unsigned char to uint16_t
Due to standard structure padding, the structure size does not change
unless alignment is 1-byte (instead of 2-byte or more)

Note: existing application use which accesses the struct member
(using MBEDTLS_PRIVATE) is compatible on little-endian platforms,
but not compatible on big-endian platforms.  The enum values for
the lower byte of MBEDTLS_SSL_VERSION_TLS1_2 and of
MBEDTLS_SSL_VERSION_TLS1_3 matches MBEDTLS_SSL_MINOR_VERSION_3 and
MBEDTLS_SSL_MINOR_VERSION_4, respectively.

Note: care has been taken to preserve serialized session format,
which uses only the lower byte of the TLS version.

It also fixes a comment on the required size of the temporary value

A previous commit has changed the signature of mpi_mul_hlp(), making
the length of the output explicit.

This commit adjusts mbedtls_mpi_mul_int() to this change.

Along the way, we make the code simpler and more secure by not calculating
the minimal limb-size of A. A previous comment indicated that this was
functionally necessary because of the implementation of mpi_mul_hlp() --
if it ever was, it isn't anymore.

fee261a505 Adjust mbedtls_mpi_mul_mpi() to new signature of mpi_mul_hlp() 
The previous commit has changed the signature of mpi_mul_hlp(),
making the length of the output explicit.

This commit adjusts the call-site in mbedtls_mpi_mul_mpi() to
this new signature.

A notable change to the multiplication strategy had to be made:
mbedtls_mpi_mul_mpi() performs a simple row-wise schoolbook
multiplication, which however was so far computed iterating
rows from top to bottom. This leads to the undesirable consequence
that as lower rows are calculated and added to the temporary
result, carry chains can grow. It is simpler and faster to
iterate from bottom to top instead, as it is guaranteed that
there will be no carry when adding the next row to the previous
temporary result: The length of the output in each iteration
can be fixed to len(B)+1.

defe56928e Make length of output explicit in mpi_mul_hlp() 
The helper `mpi_mul_hlp()` performs a multiply-accumulate
operation `d += s * b`, where `d,b` are MPIs and `b` is a scalar.

Previously, only the length of `s` was specified, while `d` was
assumed to be 0-terminated of unspecified length.

This was leveraged at the end of the core multiplication steps
computingg the first `limb(s)` limbs of `d + s*b`: Namely, the
routine would keep on adding the current carry to `d` until none
was left. This can, in theory, run for an arbitrarily long time
if `d` has a tail of `0xFF`s, and hence the assumption of
`0`-termination.

This solution is both fragile and insecure -- the latter because
the carry-loop depends on the result of the multiplication.

This commit changes the signature of `mpi_mul_hlp()` to receive
the length of the output buffer, which must be greater or equal
to the length of the input buffer.

It is _not_ assumed that the output buffer is strictly larger
than the input buffer -- instead, the routine will simply return
any carry that's left. This will be useful in some applications
of this function. It is the responsibility of the caller to either
size the output appropriately so that no carry will be left, or
to handle the carry.

NOTE: The commit leaves the library in a state where it cannot
      be compiled since the call-sites of mpi_mul_hlp() have
      not yet been adjusted. This will be done in the subsequent
      commits.

a9b6c8074a Fix psa_mac_verify() returning BUFFER_TOO_SMALL 
It doesn't make sense for psa_mac_verify() to return
PSA_ERROR_BUFFER_TOO_SMALL since it doesn't have an output buffer. But this
was happening when requesting the verification of an unsupported algorithm
whose output size is larger than the maximum supported MAC size, e.g.
HMAC-SHA-512 when building with only SHA-256 support. Arrange to return
PSA_ERROR_NOT_SUPPORTED instead.

695c4cb7ea If a cipher algorithm is not supported, fail during setup 
In some cases, a cipher operation for an unsupported algorithm could succeed
in psa_cipher_{encrypt,decrypt}_setup() and fail only when input is actually
fed. This is not a major bug, but it has several minor downsides: fail-late
is harder to diagnose for users than fail-early; some code size can be
gained; tests that expect failure for not-supported parameters would have to
be accommodated to also accept success.

This commit at least partially addresses the issue. The only completeness
goal in this commit is to pass our full CI, which discovered that disabling
only PSA_WANT_ALG_STREAM_CIPHER or PSA_WANT_ALG_ECB_NO_PADDING (but keeping
the relevant key type) allowed cipher setup to succeed, which caused
failures in test_suite_psa_crypto_op_fail.generated in
component_test_psa_crypto_config_accel_xxx.

Changes in this commit:
* mbedtls_cipher_info_from_psa() now returns NULL for unsupported cipher
  algorithms. (No change related to key types.)
* Some code that is only relevant for ECB is no longer built if
  PSA_WANT_ALG_ECB_NO_PADDING is disabled.
