Gilles Peskine c3ccae7faf Unit test function for mbedtls_ecp_muladd
Write a simple unit test for mbedtls_ecp_muladd().

Add just one pair of test cases. One of them causes the argument to
fix_negative to have an argument with an all-bits-zero least
significant limb which briefly triggered a branch in Mbed TLS 2.26+.
See https://github.com/ARMmbed/mbedtls/issues/4296 and
https://github.com/ARMmbed/mbedtls/pull/4297.

Ronald Cron d239794deb tests: Add mbedtls_test_ prefix to hexcmp()
Add mbedtls_test_ prefix to hexcmp() test helper
function.

Command to change *.function files:
find . -name "*.function" -exec awk -i inplace \
    '{sub(/hexcmp\>/,"mbedtls_test_&")}1' {} \;

Manuel Pégourié-Gonnard 7a28e99fa0 Expand test to ensure no assumption on output
The functions don't require the caller to preserve the content of the output
parameter - let's ensure that they don't assume that.

Azim Khan 46c9b1f196 Fix test functions and data after moving hexify/unhexify out
- Separate string and hex parameter as unhexify is moved out of the function. It's input should only be hex.
- Fix test mbedtls_ccm_encrypt_and_tag that grows input message buffer with tag
- Add missing expected length parameter in ECP TLS tests
- Add deleted TEST_ASSERT and mbedtls calls that got removed in script based code generation

Manuel Pégourié-Gonnard 46ba7f3a92 Avoid running useless code in tests
With max_ops set to 0 or a very large value, we would always be doing an extra
full operation for no testing value.

Manuel Pégourié-Gonnard 4b9c51ef32 Rename EARLY_RETURN -> RESTARTABLE
This is more consistent with function and context names.

Manuel Pégourié-Gonnard 54dd6527f0 Introduce muladd_restartable() and its sub-context
Only the administrative parts for now, not actually restartable so far.

Manuel Pégourié-Gonnard 8467e6848d Stop checking for argument change
This was intended to detect aborted operations, but now that case is handled
by the caller freeing the restart context.

Also, as the internal sub-context is managed by the callee, no need for the
caller to free/reset the restart context between successful calls.

Manuel Pégourié-Gonnard b739a712d1 Start moving to new design/API
Following discussion in the team, it was deemed preferable for the restart
context to be explicitly managed by the caller.

This commits in the first in a series moving in that directly: it starts by
only changing the public API, while still internally using the old design.
Future commits in that series will change to the new design internally.

The test function was simplified as it no longer makes sense to test for some
memory management errors since that responsibility shifted to the caller.

Manuel Pégourié-Gonnard 9c5c78ff5c Fix indicative values of ops counts
Previous measurements were wrong due to counting multiplication by a small
constant as a full multiplication, which it is not.

Manuel Pégourié-Gonnard 78d564a841 Add check for changing arguments
In case of argument change, freeing everything is not the most efficient
(wastes one free()+calloc()) but makes the code simpler, which is probably
more important here

Manuel Pégourié-Gonnard 77af79a324 Add proper allocation of restart context
We'll need to store MPIs and other things that allocate memory in this
context, so we need a place to free it. We can't rely on doing it before
returning from ecp_mul() as we might return MBEDTLS_ERR_ECP_IN_PROGRESS (thus
preserving the context) and never be called again (for example, TLS handshake
aborted for another reason). So, ecp_group_free() looks like a good place to
do this, if the restart context is part of struct ecp_group.

This means it's not possible to use the same ecp_group structure in different
threads concurrently, but:
- that's already the case (and documented) for other reasons
- this feature is precisely intended for environments that lack threading

An alternative option would be for the caller to have to allocate/free the
restart context and pass it explicitly, but this means creating new functions
that take a context argument, and putting a burden on the user.
