SSLeay 0.6.4 30/08/96 eay

I've just finished some test builds on Windows NT, Windows 3.1, Solaris 2.3,
Solaris 2.5, Linux, IRIX, HPUX 10 and everthing seems to work :-).

The main changes in this release

- Thread safe.  have a read of doc/threads.doc and play in the mt directory.
  For anyone using 0.6.3 with threads, I found 2 major errors so consider
  moving to 0.6.4.  I have a test program that builds under NT and
  solaris.
- The get session-id callback has changed.  Have a read of doc/callback.doc.
- The X509_cert_verify callback (the SSL_verify callback) now
  has another argument.  Have a read of doc/callback.doc
- 'ca -preserve', sign without re-ordering the DN.  Not tested much.
- VMS support.
- Compile time memory leak detection can now be built into SSLeay.
  Read doc/memory.doc
- CONF routines now understand '\', '\n', '\r' etc.  What this means is that
  the  SPKAC object mentioned in doc/ns-ca.doc can be on multiple lines.
- 'ssleay ciphers' added, lists the default cipher list for SSLeay.
- RC2 key setup is now compatable with Netscape.
- Modifed server side of SSL implementation, big performance difference when
	  using session-id reuse.
