If we provide low order element as a public key and the implementation
maps the point in infinity to the origin, we can force the common secret
to be zero.
According to the standard (RFC 7748) this is allowed but in this case
the primitive must not be used in a protocol that requires contributory
behaviour.
Mbed Crypto returns an error when the result is the point in the
infinity and does not map it to the origin. This is safe even if used in
protocols that require contributory behaviour.
This commit adds test cases that verify that Mbed Crypto returns an
error when low order public keys are processed.
The low order elements in the test cases were taken from this website:
https://cr.yp.to/ecdh.html
The tests we had for ECP point multiplication were tailored for test
vectors symulating crypto operations and tested a series of operations
against public test vectors.
This commit adds a test function that exercises a single multiplication.
This is much better suited for negative testing than the preexisting
test.
Only one new test case is added that exercises a fraction of an existing
test, just to make sure that the test is consistent with the existing
test functions.

The documentation doesn't explicitly say whether it's allowed or not.
This currently works with the default software implementation, but
only by accident. It isn't guaranteed to work with new ciphers or with
alternative implementations of individual ciphers, and it doesn't work
with the PSA wrappers. So don't do it.
Run ssl-opt.sh on x86_32 with ASan. This may detect bugs that only
show up on 32-bit platforms, for example due to size_t overflow.
For this component, turn off some memory management features that are
not useful, potentially slow, and may reduce ASan's effectiveness at
catching buffer overflows.
On Windows, rename() fails if the new filename already exists.
Use the Windows specific function MoveFileExA with the
MOVEFILE_REPLACE_EXISTING flag set instead to do renames.
Remove the ssl_cert_test sample application, as it uses
hardcoded certificates that moved, and is redundant with the x509
tests and applications. Fixes#1905.
