finalized.
Move header to passhash9.h and rename the functions to be passhash9
specific ({generator,check}_passhash9)
Add an algorithm identifer field. Currently only id 0 is defined, for
HMAC(SHA-1), but this opens up for using HMAC(SHA-512) or HMAC(SHA-3)
or CMAC(Blowfish) or whatever in the future if necessary. Increase the
salt size to 96 bits and the PRF output size to 192 bits.

password hashing schemes.
Increase salt size to 80 bits.
Research shows that virtually no other PBKDF2 implementations support
anything but SHA-1; for ease of implementation elsehwere switch back
from SHA-512 to SHA-1. Should be mostly harmless; it limits total
entropy of the password to a maximum of 160 bits, but this is unlikely
anyway.
Use two bytes to specify the work factor for future-proofing.
Add a test.

the passhash example to the library. Support variable work factors;
default work factor of 10 takes about half a second to do one password
on my Core2. Switch to using SHA-512 instead of SHA-1 in PBKDF2. To keep
the output evenly sized for base64 purposes, reduce PBKDF2 output size by
one byte (to 112 bits).

and iteration count, force it to be passed to each call to derive_key.
So remove current_salt, set_iterations, new_random_salt, and change_salt
functions from S2K interface.
Update examples and test application to match.
While I was in there, change the passhash example to use 64 bit salts
and 128 bit PBKDF2 outputs.

Invalid_Argument just a typedef for std::invalid_argument. Make
Botan::Exception a typedef for std::runtime_error. Make Memory_Exhaustion
a public exception, and use it in other places where memory allocations
can fail.

bswap.h); too many external apps rely on loadstor.h existing.
Define 64-bit generic bswap in terms of 32-bit bswap, since it's
not much slower if 32-bit is also generic, and much faster if
it's not. This may be quite helpful on 32-bit x86 in particular.
Change formulation of generic 32-bit bswap. It may be faster or
slower depending on the CPU, especially the latency and throuput
of rotate instructions, but should be faster on an ideally
superscalar processor with rotate instructions (ie, what I expect
future CPUs to look more like).

Fixes for the amalgamation generator for internal headers.
Remove BOTAN_DLL exporting macros from all internal-only headers;
the classes/functions there don't need to be exported, and
avoiding the PIC/GOT indirection can be a big win.
Add missing BOTAN_DLLs where necessary, mostly gfpmath and cvc
For GCC, use -fvisibility=hidden and set BOTAN_DLL to the
visibility __attribute__ to export those classes/functions.

Change serp_simd_sbox.h's header guard to use the leading BOTAN_ prefix for
proper macro namespacing.

Remove support for (unused) modset settings.
Move tss, fpe, cryptobox, and aont to new dir constructs
