until we are actually setting a key. This avoids the problem of
prototype objects consuming not just memory but the precious few bytes
of mlock'able memory that we're given by Linux.
Use clear_mem instead of a loop in BigInt::mask_bits
If OS2ECP encounters an invalid format type, include what type it was
in the exception message.

using a custom allocator. Currently our allocator just does new/delete
with a memset before deletion, and the mmap and mlock allocators have
been removed.

the parameters of the key length. Instead define a new function which
returns a simple object which contains this information.
This definitely breaks backwards compatability, though only with code
that directly manipulates low level objects like BlockCipher*s
directly, which is probably relatively rare.
Also remove some deprecated accessor functions from lookup.h. It turns
out block_size_of and output_size_of are being used in the TLS code; I
need to remove them from there before I can delete these entirely.
Really that didn't make much sense, because they assumed all
implementations of a particular algorithm will have the same
specifications, which is definitely not necessarily true, especially
WRT key length. It is much safer (and probably simpler) to first
retrieve an instance of the actual object you are going to use and
then ask it directly.

the initial/default length of the array, update all users to instead
pass the value to the constructor.
This is a old vestigal thing from a class (SecureBuffer) that used
this compile-time constant in order to store the values in an
array. However this was changed way back in 2002 to use the same
allocator hooks as the rest of the containers, so the only advantage
to using the length field was that the initial length was set and
didn't have to be set in the constructor which was midly convenient.
However this directly conflicts with the desire to be able to
(eventually) use std::vector with a custom allocator, since of course
vector doesn't support this.
Fortunately almost all of the uses are in classes which have only a
single constructor, so there is little to no duplication by instead
initializing the size in the constructor.

Add a second template param to SecureVector which specifies the initial
length.
Change all callers to be SecureVector instead of SecureBuffer.
This can go away in C++0x, once compilers implement N2712 ("Non-static
data member initializers"), and we can just write code as
SecureVector<byte> P{18};
instead

just too fragile and not that useful. Something like Java's checked exceptions
might be nice, but simply killing the process entirely if an unexpected
exception is thrown is not exactly useful for something trying to be robust.

Remove encrypt, decrypt - replace by cipher() and cipher1()
Remove seek() - not well supported/tested, I want to redo with a new interface
once CTR and OFB modes become stream ciphers.
Rename resync to set_iv()
Remove StreamCipher::IV_LENGTH and add StreamCipher::valid_iv_length() to
allow multiple IV lengths (as for instance Turing allows, as would Salsa20
if XSalsa20 were supported).

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).
