This is necessary for the case where the public part of an EC keypair
needs to be computed from the private part - either because it was not
included (it's an optional component) or because it was compressed (a
format we can't parse).
This changes the API of two public functions: mbedtls_pk_parse_key() and
mbedtls_pk_parse_keyfile().
Tests and programs have been adapted. Some programs use a non-secure RNG
(from the test library) just to get things to compile and run; in a
future commit this should be improved in order to demonstrate best
practice.

Fix trivial faulty calls in ECP test suite and ECP/ECJPAKE self-tests (by
adding a dummy RNG).
Several tests suites are not passing yet, as a couple of library
function do call ecp_mul() with a NULL RNG. The complexity of the fixes
range from "simple refactoring" to "requires API changes", so these will
be addressed in separate commits.

Mbed OS now provides POSIX-like time functions, although not alarm() nor

although there isn't much context around why the restriction was
imposed: 63e7ebaaa1 ("Add material for generating yotta module"). In
2015, Mbed OS was quite a different thing: no RTOS, no threads, just an
asynchronous event loop model. I'd suppose the asynchronous event loop
model made it difficult before to implement MBEDTLS_TIMING_C on Mbed OS,

The password stretching (using slow and/or memory hard hashes) in PAKEs
usually serves two purposes:
- Defending against server compromise impersonation attacks. J-PAKE is an
augmented PAKE and as such, stores a password-equivalent and defending
against this class of attacks is out of scope.
- Preventing offline dictionary attacks. J-PAKE is proven to be zero
knowledge and leaks no information beyond the fact if the passwords
matched and offline dictionary attack is not possible.
In summary: J-PAKE does not benefit from pasword stretching and is
unlikely to be an input. This part of the API is not necessary at this
point and can be added later.

Using memory hard functions with PAKEs is the more secure option. It

The main purpose of psa_pake_get_key_share() is to provide a more
straightforward and convenient call flow for regular PAKEs. Most PAKEs
have a single key share and need a flow like this:
op=PSA_PAKE_OPERATION_INIT;
psa_pake_setup();
psa_pake_get_key_share();
psa_pake_set_key_share();
psa_pake_get_implicit_key();
Adding psa_pake_get/set_key_share() functions cuts out the
psa_pake_data_t constants from the users vision, hiding complexity that
exists only for unrelated PAKEs that aren't relevant for the user.
This comes with the cost of the two additional API functions that we need
to maintain.
Since the current stream of work focuses on enabling J-PAKE, there are
no benefits to these functions for now.
Once algorithms that can benefit from this simplification are added,
adding back these functions can be reconsidered.

PAKE protocols make use of a range of cryptographic schemes and
primitives. Standards allow for several options to use for each of them.
They call the combination of specific algorithms cipher suites,
configurations or options.
Cipher suites are represented by a separate data type for several
reasons:
1. To allow for individual PAKE protocols to provide pre-defined cipher
suites.
2. To organise cipher suites into a unit that can be handled separately
from the operation context. The PAKE operation flow is already
complex, will be even more so when key confirmation is added.
Handling them separately should reduce the surface of the interface
the application developer needs to pay attention at any given time.

upper bounds for the size of incoming and outgoing records,
which can be used to size application data buffers apporpriately
before passing them to mbedtls_ssl_{read,write}(). However,
there are other factors which influence such upper bounds,

which should be taken into account.
There should be more general APIs for querying the maximum

For the maximum size of incoming records, a new API will be
