Local fix

Problem summary

• 1. Add Trust anchors for IBM cloud
  We need to be able to populate keystore with the trust anchors
  needed to deploy and operate within the IBM Cloud.
  2. Private key objects leak in HSM
  iKeyman sometimes leak private key objects in HSM. The problem
  is the public key attribute "CKA_VERIFY" (keys used for
  verifying) is required to be set to TRUE to list both the
  private key and Trusted cert entry and thus avoid private key
  leak problem. In iKeyman code, this attribute was set to default
  value "FALSE".
  3. Vulnerability reported by IBM AppScan
  IBM Appscan reports that BufferedReader.readLine() method is
  prone to Allocation of Resources Without Limits and Reliance of
  untrusted input. (i.e. exhaust heap)
  

Problem conclusion

• 1. Add Trust anchors for IBM cloud
  Following options are introduced to add trust anchors for IBM
  cloud to the existing keystore
  -ibmcloudtrust which applies to the -create and -convert
  operations.
  -addtrust adds legacy default set of trusted CAs or those
  required for deployment within IBM Cloud.
  2. Private key objects leak in HSM
  iKeyman code is fixed to set this attribute CKA_VERIFY to TRUE.
  Also, iKeyman CLI command parameter "-crypto" is modified to
  enable the user to pick up the token library filename from
  PKCS11 configuration file specified for the IBMPKCS11Impl
  security provider in java.security file. For more information,
  please refer to the latest iKeyman user guide.
  3. Vulnerability reported by IBM AppScan
  Replace BufferedReader.readLine() method with an internal API
  that imposes limits both on the length of each line and total
  number of lines read.
