Add a comment that the limitation of the personalization string
being a maximum of 64 characters is due to the implementation and
not the specification (but it makes it easy to implement, and in
this particular case 64 characters is probably fine).
Add some tests for the personalization option, generated by the
Skein reference implementation.
Disable stripping whitespace in checks/misc.cpp:strip - it strips
the personalization tag, which breaks the test, and isn't needed
otherwise because the test files are well-formed.

up during the Fedora submission review, that each source file include some
text about the license. One handy Perl script later and each file now has
the line
Distributed under the terms of the Botan license
after the copyright notices.
While I was in there modifying every file anyway, I also stripped out the
remainder of the block comments (lots of astericks before and after the
text); this is stylistic thing I picked up when I was first learning C++
but in retrospect it is not a good style as the structure makes it harder
to modify comments (with the result that comments become fewer, shorter and
are less likely to be updated, which are not good things).

to have been so! Change MDx_HashFunction::hash to a new compress_n
which hashes an arbitrary number of blocks. I had a thought this might
reduce a bit of loop overhead but the results were far better than I
anticipated. Speedup across the board of about 2%, and very
noticable (+10%) increases for MD4 and Tiger (probably b/c both
of those have so few instructions in each iteration of the
compression function).

It turned out many files were including base.h merely to get other
includes (like types.h, secmem.h, and exceptn.h). Those have been changed
to directly include the files containing the declarations that code needs.

the asm MPI modules are detected and used correctly (at least on x86-64
and x86).

the normal Botan base classes. This required making data members of
MD4, MD5, and Serpent protected rather than private, which is not very
good style IMO. On the other hand it allows for removing a bit of duplicated
code, and also has the nice effect that a pointer to a Serpent_IA32 can be
used right as a Serpent object, which makes sense anyway since they implement
the same algorithm. The C++ files in the *_ia32 modules are now simply hooks
between the virtual function call runtime and the assembly code.

rather than silently replacing the C++ versions. Instead they are silently
replaced (currently, at least) at the lookup level: we switch off the set
of feature macros set to choose the best implementation in the current
build configuration. So you can have (and benchmark) MD5 and MD5_IA32
directly against each other in the same program with no hassles, but if
you ask for "MD5", you'll get maybe an MD5 or maybe MD5_IA32.
Also make the canonical asm names (which aren't guarded by C++ namespaces)
of the form botan_<algo>_<arch>_<func> as in botan_sha160_ia32_compress,
to avoid namespace collisions.
This change has another bonus that it should in many cases be possible to
derive the asm specializations directly from the original implementation,
saving some code (and of course logically SHA_160_IA32 is a SHA_160, just
one with a faster implementation of the compression function, so this seems
reasonable anyway).

Correct the configure program so modules are not autoloaded if their
dependences are not available. (Eg, --no-module=mdx_hash will disable
MD4, MD5, SHA-1, etc rather than cause a compliation failure)
