This part can fail, so it shouldn't be intermixed with the part that
can't fail and is there to ensure all structures are in a clean state,
should any error happen.
Fortunately, the part that should be split out already had a function
doing it: reset_checksum. Also, handshake_params_init had only one
calling site to update.

There are three family of functions: update_checksum, calc_verify,
calc_finished, that perform hashing operations and were returning void
so far. This is not correct, as hashing functions can return errors (for
example, on hardware failure when accelerated). Change them to return
int.
This commit just changes the types: for now the functions always return
0, and their return value is not checked; this will be fixed in the
next few commits.
There is a related function in TLS 1.3,
mbedtls_ssl_reset_transcript_for_hrr, which also handles hashes, and
already returns int but does not correctly check for errors from hashing
functions so far, it will also be handled in the next few commits.
There's a special case with handshake_params_init: _init functions
should return void, so we'll need to split out the part that can return
errors, see the next commit.

This patch introduces the following changes:
* Documentation for `mbedtls_ecp_modulus_setup()`
moved to `ecp_invasive.h`.
* Added invalid modulus selector `MBEDTLS_ECP_MOD_NONE`.
* Adjusted negative tests to use invalid selectors.
* Reworded documentation.

This patch introduces a new static method, responsible
for automatically initialising an modulus structure,
based on the curve id and a modulus type selector.

This commit add support to detect if openssl used for testing
supports static ECDH key exchange. Skip the ciphersutes if
openssl doesn't support them.

Previously calling get_num_ops more than once would have ended up with ops
getting double counted, and not calling inbetween completes would have ended up
with ops getting missed. Fix this by moving this to where the work is actually
done, and add tests for double calls to get_num_ops().

Comment originated from original version of this code, and the newer comment
which was added when it was pulled into a seperate function covers all cases.

We do not need to expect to fail, running another complete in either sign or
verify after successful completion should also return BAD_STATE.
