/**
  Initialize debug agent.

  This function is used to set up debug environment to support source level debugging.
  If certain Debug Agent Library instance has to save some private data in the stack,
  this function must work on the mode that doesn't return to the caller, then
  the caller needs to wrap up all rest of logic after InitializeDebugAgent() into one
  function and pass it into InitializeDebugAgent(). InitializeDebugAgent() is
  responsible to invoke the passing-in function at the end of InitializeDebugAgent().

  If the parameter Function is not NULL, Debug Agent Libary instance will invoke it by
  passing in the Context to be its parameter.

  If Function() is NULL, Debug Agent Library instance will return after setup debug
  environment.

  @param[in] InitFlag     Init flag is used to decide the initialize process.
  @param[in] Context      Context needed according to InitFlag; it was optional.
  @param[in] Function     Continue function called by debug agent library; it was
                          optional.
