into global_state.{h,cpp}. Move all of the functions into a new
namespace Global_State_Management, though exposing global_state() into
the Botan namespace for compatability.
Also add new functions global_state_exists and
set_global_state_unless_set which may be helpful in certain tricky
initialization scenarios (eg when an application using botan also uses
a library which may or may not itself use botan).

really is only used by OpenPGP, and largely it was named S2K here
because the OpenPGP S2K was implemented years before the ones in PKCS
#5. We have a typedef of PBKDF to S2K, and an inlined get_s2k that
calls get_pbkdf for source compatability.
There doesn't seem to be any reason to have a forward for the renamed
s2k.h header - to actually use a PBKDF, you'd have to either include
lookup.h and call get_s2k / get_pbkdf, or else include an
algorithm-specific header and use it directly. In either case,
including s2k.h is neither necessary nor sufficient.

then you can't use the global PRNG but everything else still works.

PRNG everywhere. The removal of the global PRNG was generated by a
desire to remove the global library state entirely. However the real
point of this was to remove the use of globally visible _mutable_
state; of the mutable state, the PRNG is probably the least important,
and the most useful to share. And it seems unlikely that thread
contention would be a major issue in the PRNG.
Add back a global PRNG to Library_State. Use lazy initialization, so
apps that don't ever use a PRNG don't need a seeding step. Then have
AutoSeeded_RNG call that global PRNG.
Offer once again
RandomNumberGenerator& Library_State::global_rng();
which returns a reference to the global PRNG.
This RNG object serializes access to itself with a mutex.
Remove the hack known as Blinding::choose_nonce, replace with using
the global PRNG to choose a blinding nonce

Pretty much useless and unused, except for listing the module names in
build.h and the short versions totally suffice for that.

build (only libstate, utils, plus dependencies), which can be extended with
use of --enable-modules.
To add new modules to the set of always-loaded, use 'load_on always' in info.txt
Also fix a few small build problems that popped up when doing a minimal build.

the other half was relied upon by pubkey. Move the contents into those two
modules. Update deps.

back to the toplevel since most othe dependencies have been removed now
(except get_cipher which still needs changes)

and reduce all the arguments to just a bool specifying threads.
selftests: off (if desired, run passes_self_test in selftest.h)
fips140: Just ran the self tests, totally bogus option.
use_engine: On by default (that is, if OpenSSL or asm code is compiled
in, it's used by default). One can get better control over this using
the provider feature of SCAN_Name (though this doesn't handle cases like
nested algorithms yet).
secure_memory: On by default.
