[cdt-patch] Patch for GDB exitcode

[Keith Seitz <keiths@xxxxxxxxxx>]

Hi,

org.eclipse.cdt.debug.mi.commands.MIGDBShowExitCode is currently using an 
improperly-defined command to get at the exit code of the inferior. "show 
convenience" returns a list of all the installed convenience variables. 
It does not take any arguments.

Instead, use -data-evaluate-expression to get at $_exitcode. This patch 
modifies MIGDBShowExitCode.java and MIGDBShowExitCodeInfo.java to use this 
route.

(BTW, is there a way for eclipse to generate a patch against multiple 
files at once? Whenever I have more than one file selected, the 
Team->Create Patch... option is disabled.)

Keith
