x86-64, then enable SSE2 anyway because we know any x86-64 processor
does have SSE2, and the OS has to support it because it's part of the
standard ABIs.

initialize() call which must be called prior to use of any other
functions.

This caused Doxygen to think this was markup meant for it, which really
caused some clutter in the namespace page.

if we are compiling under GCC, or 0 otherwise.
Use it in cpuid.cpp for use of GCC's cpuid.h header file.
If we don't have a method of calling cpuid, print a warning.

(before 4.3). Probably will need to write asm blocks for those older
versions.

including loadstor.h actually just needed get_byte and nothing else.

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.

Relies on mfspr emulation/trapping by the kernel, which works on (at least)
Linux and NetBSD.

since it passes signed ints for whatever reason.
Ensure CALL_CPUID is always defined (previously, it would not be if on an x86
but compiled with something other than GCC, ICC, VC++).
