 Changes between 0.9.5 and 0.9.5a  [XX XXX 2000]


  *) Add compatability options to the purpose and trust code. The
     purpose X509_PURPOSE_ANY is "any purpose" which automatically
     accepts a certificate or CA, this was the previous behaviour,
     with all the associated security issues.

     X509_TRUST_COMPAT is the old trust behaviour: only and
     automatically trust self signed roots in certificate store. A
     new trust setting X509_TRUST_DEFAULT is used to specify that
     a purpose has no associated trust setting and it should instead
     use the value in the default purpose.
     [Steve Henson]

  *) Fix the PKCS#8 DSA private key code so it decodes keys again
  *) Fix the PKCS#8 DSA private key code so it decodes keys again
     and fix a memory leak.
