This is somewhat faster, especially with SIMD-ed ciphers. The ceiling on
performance looks to be CMAC, which is iterative and thus can't take advantage
of them.
Remove BOTAN_PARALLEL_BLOCKS_EAX, since it implicitly is whatever CTR is doing.
Bump CTR's default parallel blocks to 16.

But, disable warnings 4250 and 4251 in build.h with a pragma. Both seem
impossible to work around without very major code changes, and both seem
harmless AFAICT.

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).

empty anyway.
For VC++ (only user) set BOTAN_DLL to dllimport by default (for apps), and then
redefine as dllexport when building the library.

Modify ECB to use parallel encryption/decryption where possible
Add toggles in build.h specifying how many blocks to process in parallel.
Defaults to 8 blocks for all modes, which is sufficient that any likely
parallelism can be extracted (via SIMD or concurrent execution) but not
so much as to seem likely to cause cache problems (8*128 bits = 128 bytes,
or two x86 cache lines)

had been denoted with @{var:NAME}, this has changed to %{NAME}. This is
pretty much a wash for configure.pl but it makes it much easier to process
the templates using Python's string.Template. The logic being the 'var:'
prefix had been to support conditional statements in the templates (using
an 'if:' prefix), but this functionality was not being used and support
for it is removed from configure.pl in this revision.
For a similiar reason, rename a number of template variables with hyphens
in their name to use underscores instead. This is slightly more consistent
anyway (since many variable names had already used _ instead of -) but more
importantly makes them much easier to deal with using aforementioned Python
template code.
This should not result in any user-visible change (unless I messed up).

accepts options 'boost' and 'system'. Now GF(p) math (and indirectly,
ECDSA) will be enabled if --with-tr1=boost or --with-tr1=system
is passed at build time to enable a shared_ptr implementation.
Modules can now specify that they require TR1, in which case
they will only be autoloaded if a TR1 implementation was set
(they can choose which one to use by checking the feature macros
from build.h)
The gfpmath module was set to load only on request. That has
changed to load automatically (but will only do so if a TR1
impl is set as described above). CVC has also been marked
as requiring TR1. (ECDSA/ECDH are not, since they do not
use tr1 shared_ptr directly)
Update and cleanup help output. Do not print the list of modules in
--help anymore (too long); you can still get the list (in an easier to
parse format) --module-info. Reorganize the help text so the more
useful options are described closer to the top.
Fix the --with-endian and --with-unaligned-mem options: they were being
accepted but ignored.

If neither is defined when build.h is included, choose Boost.
Reorganize build.h so it is easier to find things, in particular move all
of the interesting toggles to the top of the file and all of the long
lists of modules and feature test macros to the end.

to Boost to avoid this.

inline asm (currently, if __GNUG__ is defined, which works with both
GNU C++ and Intel C++, which are the only two compilers I know of that
accept GCC's inline asm syntax). Use that in bswap.h - previously we
would try to use inline asm even with VC++ or other compilers not supporting
inline asm.

Moved XS, Boost Python, and SWIG wrappers to new toplevel directory 'wrappers'
Moved NIST X.509 test suite into checks directory
Move the build information used by configure.pl to src/build-data
Move scripts directory to doc (for lack of a better spot)
