Remove algo factory, engines, global RNG, global state, etc.

Convert all uses of Algorithm_Factory and the engines to using Algo_Registry

The shared pool of entropy sources remains but is moved to EntropySource.
With that and few remaining initializations (default OIDs and aliases)
moved elsewhere, the global state is empty and init and shutdown are no-ops.
Remove almost all of the headers and code for handling the global
state, except LibraryInitializer which remains as a compatability stub.

Update seeding for blinding so only one hacky almost-global RNG
instance needs to be setup instead of across all pubkey uses (it uses
either the system RNG or an AutoSeeded_RNG if the system RNG is not
available).
