On a valid RSA public key, mbedtls_rsa_export should succeed if you
ask for the public fields, but fail if you ask for private fields. The
code was expecting to succeed when asking for private fields, so
failed on every valid RSA public key.
Other third-party components can now be added by just adding lines to
the definitions of @thirdparty_header_dirs and
@thirdparty_source_dirs.
No semantic change. The output does not change at all.

Some code paths want to access members of the mbedtls_rsa_context structure.
We can only do that when using our own implementation, as otherwise we don't
know anything about that structure.
(Only the top-level ones, ie, for each call to eg asn1_get_mpi(), ensure
there's at least one test case that makes this call fail in one way, but don't
test the various ways to make asn1_get_mpi fail - that should be covered
elsewhere.)
- the new checks added by the previous commits needed exercising
- existing tests sometimes had wrong descriptions or where passing for the
wrong reason (eg with the "length mismatch" test, the function actually
failed before reaching the length check)
- while at it, add tests for the rest as well
The valid minimal-size key was generated with:
openssl genrsa 128 2>/dev/null | openssl rsa -outform der 2>/dev/null | xxd -p
When parsing a PKCS#1 RSAPrivateKey structure, all parameters are always
present. After importing them, we need to call rsa_complete() for the sake of
alternative implementations. That function interprets zero as a signal for
"this parameter was not provided". As that's never the case, we mustn't pass
any zero value to that function, so we need to explicitly check for it.

* #346: Improve robustness and testing of mbedtls_mpi_copy
Exercise the library functions with calloc returning NULL for a size
of 0. Make this a separate job with UBSan (and ASan) to detect
places where we try to dereference the result of calloc(0) or to do
things like
buf = calloc(size, 1);
if (buf == NULL && size != 0) return INSUFFICIENT_MEMORY;
memcpy(buf, source, size);
which has undefined behavior when buf is NULL at the memcpy call even
if size is 0.
This is needed because other test components jobs either use the system
malloc which returns non-NULL on Linux and FreeBSD, or the
memory_buffer_alloc malloc which returns NULL but does not give as
useful feedback with ASan (because the whole heap is a single C
object).
