libssh2_trace_sethandler - set a trace output handler

       Added in libssh2 version 1.2.3

libssh2                                            15 Jan 2010                       libssh2_trace_sethandler(3)

       libssh2_trace_sethandler  installs a trace output handler for your application.  By default, when tracing
       has been switched on via a call to libssh2_trace(), all output is written  to  stderr.  By  calling  this
       method and passing a function pointer that matches the libssh2_trace_handler_func prototype, libssh2 will
       call  back  as  it generates trace output. This can be used to capture the trace output and put it into a
       log file or diagnostic window.  This function has no effect unless libssh2  was  built  to  support  this
       option, and a typical "release build" might not.

       context can be used to pass arbitrary user defined data back into the callback when invoked.
