fdb77cdae3 psa_crypto_pake: internally call to psa_pake_abort() in case of errors
In this way, in case of error, it is not possible to continue using
the same psa_pake_operation_t without reinitializing it.
This should make the PSA pake's behavior closer to what expected by
the specification

060009518b mpi_exp_mod: fix out of bounds access
The table size was set before the configured window size bound was

9c09326572 mpi_mod_exp: be pedantic about right shift
The window size starts giving diminishing returns around 6 on most
platforms and highly unlikely to be more than 31 in practical use cases.
Still, compilers and static analysers might complain about this and
better to be pedantic.

3646ff02ad mpi_exp_mod: move X next to the precomputed values
With small exponents (for example, when doing RSA-1024 with CRT, each
prime is 512 bits and we'll use wsize = 5 which may be smaller that the
maximum - or even worse when doing public RSA operations which typically
have a 16-bit exponent so we'll use wsize = 1) the usage of W will have
pre-computed values, then empty space, then the accumulator at the very
end.

Move X next to the precomputed values to make accesses more efficient
and intuitive.

844614814e mpi_exp_mod: remove memory ownership confusion
Elements of W didn't all have the same owner: all were owned by this
function, except W[x_index]. It is more robust if we make a proper copy
of X.

b764ee1603 mpi_exp_mod: protect out of window zeroes
Out of window zeroes were doing squaring on the output variable
directly. This leaks the position of windows and the out of window
zeroes.

Loading the output variable from the table in constant time removes this
leakage.

79f6b6bb1b tls: psa_pake: fixing mbedtls_psa_ecjpake_write_round()
It might happen that the psa_pake_output() function returns
elements which are not exactly 32 or 65 bytes as expected, but
1 bytes less.
As a consequence, insted of hardcoding the expected value for
the length in the output buffer, we write the correct one as
obtained from psa_pake_output()
