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.

and a random number generator, and the other taking a group and a
preset private key value. The DL private keys instead have on
constructor for this; if the x value is zero, then a new random key is
created. For consistency, do this with ECC as well.
ECDH actually didn't have one of these constructors, forcing you to
either load from PKCS #8 or else use a random key.
Rename EC_Domain_Params to EC_Group, with a typedef for compatability.
More doc updates.

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.

keys so far, private keys not changed) that takes an
AlgorithmIdentifier and a MemoryRegion<byte>&. This performs the X.509
decoding. It is not possible anymore to create uninitialized PK
objects.
