66e677aedd Introduce new RSA API. 
This also:
a) deprecates the old RSA and PKCS#1 API.
b) reverts the changes done to them in order to make the now deprecated API
   compatible again with the last release.

The fixes commit mentioned below is the testcase for the Bleichenbacher
attack, which works now again as expected.

Fixes: 9d03c38e ("add flags to `der_decode_sequence()`")

95790221fb Add free() function to password_ctx 
The user can now pass a `free()` function pointer that will be used to
free the memory that has been allocated by the `callback()`.
If `free()` is NULL, the library will still call `XFREE()`.

03515d5611 Move password buffer into the library 
The design before was not completely fine. The user had to allocate the
buffer and passed ownership to the library.
As of [0] this seems to be a problem in some environments.

63091c9e5c Add possibility to use different hash algorithms in RSAES-OAEP 
The hash algorithms used in the MGF and to create the hash of the Label
must not forcibly be the same. This change allows to use different
algorithms.

Unfortunately this breaks the API if you use one of:
* `rsa_decrypt_key_ex()`
* `rsa_encrypt_key_ex()`
* `pkcs_1_oaep_decode()`
* `pkcs_1_oaep_encode()`

The `rsa_decrypt_key()` and `rsa_encrypt_key()` macros are still the same.
