Hanno Becker 91c194dabb Add and document an RSA-specific error code for unsupported exports 
E.g., a private key on an external chip might not be exportable to RAM.

Hanno Becker e1582a832b Add expectation when testing RSA key import/export 
This commit adds a flag to the RSA import/export tests indicating whether it is
expected that a full RSA keypair can be set up from the provided parameters.

Further, the tests of `mbedtls_rsa_import` and `mbedtls_rsa_import_raw` are
expanded to perform key checks and an example encryption-decryption.

Hanno Becker 2f8f06aa25 Don't always recompute context length in mbedtls_rsa_get_len 
This commit changes the implementation of `mbedtls_rsa_get_len` to return
`ctx->len` instead of always re-computing the modulus' byte-size via
`mbedtls_mpi_size`.

Hanno Becker 2cca6f3290 Always deduce N from P, Q in mbedtls_rsa_complete 
Previously, a parameter set of (-, P, Q, -, E) was completed, but (-, P, Q, D,
E) wasn't - this is odd.

Hanno Becker 13be990114 Correct expectation in DHM test in ssl-opt.sh 
The previous test expected a DHM group generator of size 2048 bits, while with
the change to RFC 7919, the base is 2, so has bit-size 2.

The origin of the primes in RFC 5114 is undocumented and their use therefore
constitutes a security risk.

Hanno Becker 6428f8d78e Let ssl-opt.sh gracefully fail is SSL_MAX_CONTENT_LEN is not 16384 
Some tests in ssl-opt.sh require MBEDTLS_SSL_MAX_CONTENT_LEN to be set to its
default value of 16384 to succeed. While ideally such a dependency should not
exist, as a short-term remedy this commit adds a small check that will at least
lead to graceful exit if that assumption is violated.

Janos Follath aa325d7b7f DHM: Fix dhm_check_range() always returning 0 
Although the variable ret was initialised to an error, the
MBEDTLS_MPI_CHK macro was overwriting it. Therefore it ended up being
0 whenewer the bignum computation was successfull and stayed 0
independently of the actual check.

Janos Follath 4b151fabb7 DHM: Add negative tests for parameter checking

parameters are not in the range. This commit adds tests for signalling
this problem as well as a couple of other negative tests.

Hanno Becker c526696c05 Add tests for messages beyond 16384 bytes to ssl-opt.sh 
This commit adds four tests to ssl-opt.sh testing the library's behavior when
`mbedtls_ssl_write` is called with messages beyond 16384 bytes. The combinations
tested are TLS vs. DTLS and MBEDTLS_SSL_MAX_FRAGMENT_LENGTH enabled vs. disabled.

Hanno Becker d4a872ee67 Rename internal MBEDTLS_ENTROPY_HAVE_STRONG to ENTROPY_HAVE_STRONG 
This commit renames the test-only flag MBEDTLS_ENTROPY_HAVE_STRONG to ENTROPY_HAVE_STRONG to make it more transparent
that it's an internal flag, and also to content the testscript tests/scripts/check-names.pl which previously complained
about the macro occurring in a comment in `entropy.c` without being defined in a library file.
