Ray Brown 4464d0bd84 Certificate formatting and retrieval
This change introduces the implementation of the SSLConnection methods
getpeercert and cipher. The following has been added:

    * dtls.util:      utility elements shared by other modules in this package
    * dtls.x509:      a module for X509-certificate-related functionality,
                      including formatting a certificate into a Python
                      dictionary as prescribed by the Python standard
                      library's ssl module; functionality for testing with
                      PEM-encoded certificates in the file system is included
    * yahoo-cert.pem: the current certificate of www.yahoo.com: this is a good
                      testing certificate, since it contains the subject
                      alternate name extension

Other notable changes:

    * sslconnection:  private attributes are now preceded by "_"
    * openssl:        null-ness in opaque FuncParam-derived return values is
                      now properly detected and an exception is raised as
                      expected

Ray Brown 9bb24c5d29 Initial commit: up to and including data exchange functionality
This initial commit for the PyDTLS package includes the following functionality:

    * DTLS cookie exchange, using secure hmac cookies
    * A platform-independent routing UDP demultiplexer
    * SSL handshaking over UDP using the DTLS protocol
    * Datagram exchange using the DTLS protocol
    * SSL shutdown over UDP

The package is structured as follows:

    * dtls:               top-level package
    * dtls.demux:         demultiplexer package; automatically loads a
                          demultiplexer appropriate for the currently executing
                          platform
    * dtls.demux.router:  a routing demux for platforms whose network stacks
                          cannot assign incoming UDP packets to sockets based
                          on the sockets' connection information
    * dtls.demux.osnet:   a demux that uses the operating system's UDP packet
                          routing functionality
    * dtls.err:           package-wide error handling and error definitions
    * dtls.sslconnection: a client and server-side connection class for
                          UDP network connections secured with the DTLS protocol
    * dtls.openssl:       a ctypes-based wrapper for the OpenSSL library
    * dtls.test:          test scripts, utilities, and unit tests

The following binaries are provided:

    * libeay32.dll: cryptographic portion of the OpenSSL library
    * ssleay32.dll: protocol portion of the OpenSSL library (depends on former)
    * cygcrypto-1.0.0.dll: as libeay32.dll, but with debugging symbols
    * cygssl-1.0.0.dll: as ssleay32.dll, but with debugging symbols

All binaries have been built with the MinGW tool chain, targeted for msvcr90.
The unstripped dll's can be debugged on Windows with gdb. Cygwin is not used.
