   Initialize debug agent.

 

-  This function is used to set up debug enviroment.

+  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.
