Minor version number increase since ABI was extended (new methods).

- Key rollover support:
  Lasso is now able to accept messages signed by any key declared as a signing
  key in a metadata and not just the last one. You can also decrypt encrypted
  nodes using any of a list of private keys, allowing roll-over of encryption
  certificates. Signing key roll-over is automatic, your provider just have to
  provide the new signing key in their metadata. For multiple-encryption key
  you can load another private key than the one loaded in the LassoServer
  constuctor with code like that:

      >>> import lasso
      >>> server = lasso.Server(our_metadata, first_private_key_path)
      >>> server.setEncryptionPrivateKey(second_private_key_path)

  See the FAQ file for the workflow of a proper key roll-over.

- Partial logout response now produces a specific error code when parsed by
  lasso_logout_process_response_msg()
- Bugs in lasso_assertion_query_build_request_msg() were fixed
- Processing of assertions is not stopped when checking that first level
  status code is not success, so that later code can check the second level
  status code.
- A new generic error for denied request was added,
  LASSO_PROFILE_ERROR_REQUEST_DENIED
- A new API lasso_server_load_metadata() was added to load federation files
  (XML files containing metadata from multiple providers) and to check
  signatures on them.
- Better warning and errors are reported in logs when failing to load a
  metadata file.
- Bugs around missing namespace declaration for dump file were fixed, it
  prevented reloading dumped object (like LassoLogin).
- lasso_node_get_xml_node_for_any_type() must be able to copy the content of
  an XML node to another (namespace, attribute and children). It did not, now
  it is fixed. It can be used for example to add specific attribute like
  xsi:type="string" to a Saml2AttributeValue. Here is a python snippet to do that:

      >>> import lasso
      >>> a = lasso.Saml2AttributeValue()
      >>> a.setOriginalXmlnode('<Dummy xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="string">Value</Dummy>')
      >>> print a.debug(0)
      <saml:AttributeValue xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="string">Value</saml:AttributeValue>
- support for symetric keys signatures: for a long time XMLDsig standard has
  supported HMAC signature, or signature based on a shared secret key an hash
  algorithm. Lasso now supports to share a key with another Lasso using
  service or identity provider and to verify and sign SAML exchange using this
  key. Performance can be 100 times more than with assymetric cryptography,
  i.e. RSA.
- nodes able to hold any XML attribyte (like saml:AttributeValue) contains a
  hashtable to for holding those attributes, those hashtable have a new syntax
  for attributes of another namespace than the current node namespace,
  inspired by the Python ElementTree library:

    {the_namespace}the_attribute_name

  ex:

    {http://www.w3.org/2001/XMLSchema-instance}type

  for the classic xsi:type attribute.
- xmldsig:X509Data node now possess a binding as a Lasso object. You can use
  it combined with the new class LassoSaml2KeyInformationDataType to use the
  holder-of-key subject confirmation method.
- The perfs benchmarking tools now allows to select a different metadata set
  (for example to test with different public key sizes).
- Perl minimal version for the binding was downgraded to 5
- pseudo-XSchema validation: the new XML deserializer does more to enforce
  constraints of the schema defining SAML messages. It means Lasso is less
  forgiving with non-conform implementation of SAML.
- thin-sessions mode: A new flag was added named thin-session, you can set it
  using lasso_set_flag("thin-sessions") or by setting the LASSO_FLAG
  environement variable to the string "thin-sessions". The effect of this flag
  is to remove complete storage of assertions in the LassoSession object,
  which was made mainly to support logout and the artifact binding for ID-FF
  1.2. A new thinner structure is used for supporting logout, and ID-FF 1.2
  can now use the same storage mechanism as the SAML 2 implementation for the
  artifact binding (i.e. using lasso_profile_get_artifact_message after
  artifact generation and lasso_profile_set_artifact_message before artifact
  retrieval).
- better initialization and access to SessionIndex in logout requests:
  LassoSession now store all generated SessionIndex for a session using a
  small structure, using it the LassoLogout profile can now initialize
  LassoLogout message with all of them. It's not necessary to implement this
  functionnalit� in your service or identity provider anymore.
- new LassoKey object: this new class was introduced to simplify management of
  keys when using shared key signature. But you can also use it to load
  assymetric keys. In the future it should gain API to do XML signature and
  encryptiong independently of any SAML 2.0 or ID-FF 1.2 exchange. Providing
  the first simple binding of libxmlsec to Python.
- Improvements to autoconf and automake files to compile under Darwin (Mac Os
  X) and Fedora.
- a FAQ file was started.
- added API:
