Python 2/3 compat: queue vs Queue

[labath]

It looks like this code hasn't been touched since 2013, so who knows if it even works. But fixing this should be fine anyway.

lldb/utils/lui/lui.py

 import signal
 import sys
 
-import Queue
+try:
+    import queue
+except ImportError:
+    import Queue as queue
 
 import debuggerdriver
 import cui

     signal.signal(signal.SIGINT, sigint_handler)
 
     global event_queue
-    event_queue = Queue.Queue()
+    event_queue = queue.Queue()
 
     global debugger
     debugger = lldb.SBDebugger.Create()

lldb/utils/lui/sandbox.py

 import signal
 import sys
 
-import Queue
+try:
+    import queue
+except ImportError:
+    import Queue as queue
 
 import cui
 

 
 def main(screen):
     global event_queue
-    event_queue = Queue.Queue()
+    event_queue = queue.Queue()
 
     sandbox = SandboxUI(screen, event_queue)
     sandbox.eventLoop()
