[nemiver/big-stack: 1/3] Properly set frame level during call stack parsing

[Dodji Seketeli <dodji src gnome org>]

commit 0201eae12074e6dbe4855766d6b7e79c30d53eb4
Author: Dodji Seketeli <dodji redhat com>
Date:   Sun Apr 19 20:52:36 2009 +0200

    Properly set frame level during call stack parsing
    
    	* src/dbgengine/nmv-gdbmi-parser.cc (GDBMIParser::parse_call_stack):
    	Properly set IDebugger::Frame::level during the parsing.
    	Also, don't cry when we reach "end of input" right after the
    	parsing.
    	* tests/test-gdbmi.cc (test_stack0): New test case for stack parsing.
    	(init_unit_test_suite): Hook the new test case here.
