424840e033 Call mbedtls_cipher_free() to reset a cipher context
mbedtls_cipher_reset() only restarts the operation, it doesn't
dissociate the key from the context.

139ec3b913 Don't call mbedtls_cipher_setkey twice
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.

4b317616eb Run ssl-opt.sh on 32-bit runtime
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.

383d1fa6a5 Add --internal option to list-identifiers.sh
When doing ABI/API checking, its useful to have a list of all the
identifiers that are defined in the internal header files, as we
do not promise compatibility for them. This option allows for a
simple method of getting them for use with the ABI checking script.

1dbc5a257f Fix errors in AEAD test function
It was failing to set the key in the ENCRYPT direction before encrypting.
This just happened to work for GCM and CCM.

After re-encrypting, compare the length to the expected ciphertext
length not the plaintext length. Again this just happens to work for
GCM and CCM since they do not perform any kind of padding.

b78b300b2e tests: Test crypto via the crypto submodule
Test the crypto implementation via tests from the Mbed Crypto submodule
instead of at the Mbed TLS top level.

The version test is the only test that is tested from both TLS and
Crypto, despite being entirely in libmbedcrypto. This is because the
test data is code-gen'd from the version updating script and the version
between Mbed TLS and Mbed Crypto don't necessarily always agree. The
test data must come from the top level module, as only the top level
module will have test data that matches the expected version.

aa946b2d49 Fix failure in SSLv3 per-version suites test
The test used 3DES as the suite for SSLv3, which now makes the handshake fails
with "no ciphersuite in common", failing the test as well. Use Camellia
instead (as there are not enough AES ciphersuites before TLS 1.2 to
distinguish between the 3 versions).

Document some dependencies, but not all. Just trying to avoid introducing new
issues by using a new cipher here, not trying to make it perfect, which is a
much larger task out of scope of this commit.

output of `pylint --generate-rcfile` from an unknown version of
pylint. Replace it with a file that only contains settings that are
modified from the default, with an explanation of why each setting is
modified.

The new .pylintrc was written from scratch, based on the output of
pylint on the current version of the files and on a judgement of what
to silence generically, what to silence on a case-by-case basis and
what to fix.

df9295b7ec Make ecp_get_type public
The ecp_get_type function comes handy in higher level modules and tests
as well. It is not inline anymore, to enable alternative implementations
to implement it for themselves.

28eb06df16 ECP: Catch unsupported import/export
mbedtls_ecp_read_key() module returned without an error even when
importing keys corresponding to the requested group was not
implemented.

We change this and return an error when the requested group is not
supported and make the remaining import/export functions more robust.

ffbd7e8ff3 Improve mbedtls_ecp_point_read_binary tests
Renamed the tests because they are explicitly testing Curve25519 and
nothing else. Improved test coverage, test documentation and extended
in-code documentation with a specific reference to the standard as well.

7caf8e452f Add Montgomery points to ecp_point_write_binary
The library is able to perform computations and cryptographic schemes on
curves with x coordinate ladder representation. Here we add the
capability to export such points.

e344d0f6fc Add little endian export to Bignum
The function `mbedtls_mpi_write_binary()` writes big endian byte order,
but we need to be able to write little endian in some caseses. (For
example when handling keys corresponding to Montgomery curves.)

Used `echo xx | tac -rs ..` to transform the test data to little endian.

171a7efd02 Add mbedtls_ecp_read_key
The private keys used in ECDH differ in the case of Weierstrass and
Montgomery curves. They have different constraints, the former is based
on big endian, the latter little endian byte order. The fundamental
approach is different too:
- Weierstrass keys have to be in the right interval, otherwise they are
  rejected.
- Any byte array of the right size is a valid Montgomery key and it
  needs to be masked before interpreting it as a number.

Historically it was sufficient to use mbedtls_mpi_read_binary() to read
private keys, but as a preparation to improve support for Montgomery
curves we add mbedtls_ecp_read_key() to enable uniform treatment of EC
keys.

For the masking the `mbedtls_mpi_set_bit()` function is used. This is
suboptimal but seems to provide the best trade-off at this time.
Alternatives considered:
- Making a copy of the input buffer (less efficient)
- removing the `const` constraint from the input buffer (breaks the api
and makes it less user friendly)
- applying the mask directly to the limbs (violates the api between the
modules and creates and unwanted dependency)

a778a94b7d Add little endian import to Bignum
The function `mbedtls_mpi_read_binary()` expects big endian byte order,
but we need to be able to read from little endian in some caseses. (For
example when handling keys corresponding to Montgomery curves.)

Used `echo xx | tac -rs .. | tr [a-z] [A-Z]` to transform the test data
to little endian and `echo "ibase=16;xx" | bc` to convert to decimal.
