Slightly minimize both space and time when importing a
SubjectPublicKeyInfo. Time for ECC keys stays the same.
Those tests were done with X.509 support already available, but later these
commits were split up to be independent of the X.509 feature.
Running the entire set of pem files through `x509_verify` via [0]
resp. the timing app via [1] resulted in the following data:

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.
