BTW, 1.7.15 has minor change of API that makes some things ugly in
monotone if we want to use system provided libraries.

In lookup.h there are few get_cipher functions than in 1.7.14 and
earlier versions where independent of Library_State and in 1.7.15 they
require LibraryState& as first parameter. ***

It's not big deal for monotone to change to this new interface but
_if_ we want use bundled system libraries that for some reason may be
older than 1.7.15 we would need some #ifdefs and wrappers in monotone
code.

I don't question your design decisions but LibraryState& is currently
a singleton obtained via (AFAIR) Botan::get_default() so i don't see
any reason for removing Botan::get_cipher overloads without
LibraryState& (correct me if I'm wrong).

Old overloads can be marked as deprecated but it is wise to leave them
for a while because current code base uses them.

If it's part of bigger design, ,than we'll just write some wrapper
functions with #ifdefs.


***

New get_cipher:

BOTAN_DLL Keyed_Filter* get_cipher(Library_State&, const std::string&, ...);

Old get_cipher:

BOTAN_DLL Keyed_Filter* get_cipher(const std::string&, ...);
