Remove use of look_pk from the source and examples, instead
instantiate classes directly.

performed. Up until now, each key object (eg DSA_PublicKey or
ECDH_PrivateKey) had two jobs: contain the key material, and know how
to perform any operations on that key. However because of a desire to
support alternative implementations (GNU MP, hardware, whatever),
there was a notion of operations, with the key objects containing an
op that they got via engine rather than actually implementing the
underlying algorithms directly.
Now, represent the operation as an abstract interface (typically
mapping a byte string to a byte string), and pass a plain Public_Key&
or Private_Key& to the engine. The engine does any checks it wants (eg
based on name, typeid, key sizes, etc), and either returns nothing
(I'll pass) or a pointer to a new operation that represents signatures
or encryption or what-have-you using that key.
This means that plain key objects no longer contain operations. This
is a major break with the traditional interface. On the other hand,
using these 'bare' operations without padding, KDFs, etc is 99% of the
time a bad idea anyway (and if you really need them, there are options
so you get the bare op but via the pubkey.h interfaces).
Currently this change is only implemented for DH and ECDH (ie, key
agreement algorithms). Additionally the optional engines (gnump and
openssl) have not been updated. I'll probably wait to touch those
until after I can change them all in one go for all algos.

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.

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.

Rename is_empty to empty
Remove has_items
Rename create to resize

Pretty much useless and unused, except for listing the module names in
build.h and the short versions totally suffice for that.

on when I was first doing the modularization changes.
Move pkcs8.* and x509_key.* to pk_codecs

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).

the other half was relied upon by pubkey. Move the contents into those two
modules. Update deps.
