A generic function for retrieving the AlgorithmIdentifier structure with
its parameters and adapted X509, PKCS#5 and PKCS#12 to use them.

The 3-key and 2-key Triple DES PBE functions have been replaced with a
single pkcs12_pbe() function that handles both situations (and more).

In addition this allows for some PASSWORD_MISMATCH checking

PKCS#8 encrypted key file support has been added to x509parse_key() with
