661dad10c7 Make HW-accel checkers always available. 
Since the SHA-NI checker does the same for all three versions, we only have
to make one version public. This also now enables explicit testing of the
SHA-NI blocks.

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()`")
