time() is only needed to seed the PRNG non-deterministically. If it isn't
available, do seed it, but pick a static seed.

The timing module might include time.h on its own when on
a suitable platform, even if MBEDTLS_HAVE_TIME is disabled.

Similar to the previous commit, this commit removes
the word 'multi-part' from the encrypt setup tests.

After other changes had taken place the call to
PSA_ASSERT( psa_get_key_attributes( key, &attributes ) )
was no longer needed.

Having such implementation might cause issues for those that
expect to have a working implementation.
Having a compile-time error is better in such case.

Don't depend on the default sizes in the test programs: pass explicit
request and buffer sizes.
Don't depend on MAX_CONTENT_LEN (other than it not being extremely small:
this commit assumes that it will never be less than 101).

The added null byte was accounted for twice, once by taking
opt.buffer_size+1 when allocating the buffer and once by taking opt.buffer-1
when filling the buffer. Make opt.buffer_size the size that is actually
read, it's less confusing that way.

Make sure that buf always has enough room for what it will contain. Before,
this was not the case if the buffer was smaller than the default response,
leading to memory corruption in ssl_server2.

For weistrass curves the pair is encoded as 0x04 || x || y.
Flipping one of the bits in the first byte should be a sure failure.

Force a bitflip in server key to make the raw key
agreement fail, and then verify that no key slots
are left open at the end. Use a Weierstrass curve
to have a high chance of failure upon encountering
such bitflip.

This commit alters an ASSERT_COMPARE statement
at the end of the aead_encrypt_setup test. This is to
correct a mistake introduced by the preceding PR.

This commit adds the required changes that arose from
the first round of reviewing. The total_input_data argument
has been removed and so the .data file needed to be edited
also.

Adds test data for the test case where the insufficient
memory error is forced on the driver status.

Commit adds test data for the case where the
algorithm is not supported by the driver but
the fallback option is available in the library.

A previous commit has changed the signature of mpi_mul_hlp, making the length
of the output explicit. This commit adjusts mpi_montmul() accordingly.
It also fixes a comment on the required size of the temporary value
passed to mpi_montmul() (but does not change the call-sites).

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.
