Cosmin Stejerean db59ad582a fix: remove extra block assumptions in mbedtls integration (#1323 ) The current mbedtls integration was not working for some modes. See for example #1316 and also lots of failing integration tests. For example in pattern encryptor it works on one block at a time so it cannot assume it's going to always get a buffer with a padding for an extra block. From what I can tell when the padding mode is correctly set to `MBEDTLS_PADDING_NONE` there is no extra block being written to or required. This passes all crypto unit tests and integration tests.
