https://bugzilla.mindrot.org/show_bug.cgi?id=2508

            Bug ID: 2508
           Summary: Wanting OpenSSL error messages in ssherr() for
                    SSH_ERR_LIBCRYPTO_ERROR
           Product: Portable OpenSSH
           Version: 7.1p1
          Hardware: Sparc
                OS: Solaris
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: Miscellaneous
          Assignee: unassigned-bugs at mindrot.org
          Reporter: tomas.kuthan at oracle.com

After code refactoring for library-like interfaces,OpenSSL error string
were replaced by generic and vague "error in libcrypto" message.

This enhancement asks for returning OpenSSL error strings for
SSH_ERR_LIBCRYPTO_ERROR errors.

Simple and thread-unsafe patch to add OpenSSL error strings to ssherr()

For use in single-threaded OpenSSH binaries this patch based on static
error buffer for OpenSSL error strings should be sufficient.

For library API this would hardly be suitable.
Providing contextual error messages would probably require a more
robust and flexible error message framework.
