This extends the long available OCB and EAX decryption feature. Due
to the meanwhile expired patent on OCB there is no more reason for
using EAX. Thus we forcefully use OCB if the AEAD feature flag is set
on a key.
In GNUPG mode new keys are now created with the AEAD feature flag set.
Option --rfc4880 is one way to disable this.

This change is required for use with gcc/ld's LTO feature which does
not allow common blocks. Further gcc 10 will make -fno-common the
default and thus this chnage is always needed. What a pitty.

For proper operations as a server we need to avoid global variables.
Thus we need to pass the session state CTRL to most functions. Quite
a lot of changes but fortunately straightforward to do.
