 Changes between 0.9.1c and 0.9.2

  *) Add cool BIO that does syslog (or event log on NT).
     [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]

  *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
     TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
     TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher

	Why BIO_s_log?

	BIO_s_log is useful for system daemons (or services under NT).
	It is one-way BIO, it sends all stuff to syslogd (or event log
	under NT).
