the port or connect to the subprocess. Clean up error handling during
connection initiation phase. This is an update of Python Patch 778323.

1. Remove "idle" script, it lives in Tools/scripts/ now.
2. Remove shebang from idle.py, should be called explicitly.
3. Remove obsolete test code from rpc.py; needs unit test.
Extensions must still be configured manually and there is currently one
set of extension key bindings for all platforms.
Bring NEWS.txt up to date.

SF Patch 686254 "Run IDLEfork from any directory without set-up"
Allows IDLE to run when not installed and cwd is not the IDLE directory.
I took the liberty of moving it to the startup scripts since once IDLEfork
is again a part of Python it will be superfluous and I don't want it to
be forgotten. But it is very useful for those using IDLEfork standalone!

5. If user tries to exit or restart when user code is running, interrupt

This bug, henceforth designated Freddy, was due to the mistaken
elimination of the KeyboardInterrupt exception at the previous revision.
PyShell's unix_terminate hammer was masking the problem on Linux. On W2K
the subprocess MainThread was trying to print the exception after the
SockThread had ceased to service the socket. The subprocess would then
detach and spin when the GUI created the new subprocess.
Modified Files: run.py
2. run.py: move exception printing to toplevel to allow access from main()

debugger GUI is reused with a fresh instance of the subprocess
debugger.

1. Move subprocess socket handling to a subthread - "SockThread".
2. In the subprocess, implement a queue and global completion and exit
flags. Execute code after it is passed through the queue. (Currently,
user code is executed in SockThread. The next phase of development will
move the tail of the queue to MainThread.)
3. Implement an RPC message used to shut down the execution server.
4. Improve normal and exception subprocess exits.
(At this checkin a "pass loop" interrupt doesn't work on any platform. It
will be restored for all platforms once user code execution is moved to
MainThread.)

1. Clarify that rpc.SocketIO._getresponse() currently blocks on socket.
2. Improve exception handling in subprocess when GUI terminates abruptly.

outputting an unterminated line, e.g. print "test",

Clean up the way IDLEfork handles termination of the subprocess, restore
ability to interrupt user code in Windows (so long as it's doing terminal
I/O).
1. Handle subprocess interrupts in Windows with an RPC message.
2. Run/F5 will restart the subprocess even if user code is running.
3. Restart the subprocess if the link is dropped.
4. Exit IDLE cleanly even during I/O.
4. In rpc.py, remove explicit calls to statelock, let the condition
variable handle acquire() and release().

SF Bug 676398 Doesn't handle non-built-in exceptions
1. Move exception formatting to the subprocess; allows subclassing of
exceptions, including subclasses created in the shell without
introducing excessive complexity in the RPC mechanism.
