The intent of this branch is to remove the global library state object

(Library_State, in libstate.{h,cpp}). It causes numerous 'interesting'
problems with threads, etc, and the best solution here is to move to
more or less an object-capability model, where the only objects that
a piece of code can access are those which can be referenced through
its arguments.

First things first, remove the UI 'pulse' code. It is neither necessary
nor sufficient for writing proper GUI/event driven code using Botan, has
likely never been used in real code, and, given that, causes a distressing
amount of overhead in terms of function calls made.
