I've finally finished it. The current interface in crypto.h allows
(1) to register specific ciphers (when a hw engine is present for some
cipher) at runtime, (2) to replace the whole engine for
cipher/mac/digest/bigint/public key both at runtime and compile time[0].

Currently what is left to be done is to rewrite opencdk to use the
gnutls internal api for accessing ciphers/mac/pk and write a test case
for _pkcs12_string_to_key() which was modified but not tested since then.

[0]. for compile time replacement check the *-libgcrypt.c files. Only
those need to be replaced.
