Description of problem:
When getkey is invoked with a wait period but no wait message, it core dumps.
Also, there should be an option to allow getkey to ignore Control-C and Control-
D characters. It's inability to avoid these characters can cause problems when
dealing with the Linux Progress Patch. When we used getkey to check for a
keypress in order to reset a machine's environment and reboot, it would always
do so when using the Linux Progress Patch, whether or not the key was actually
pressed. Finally, a NULL character passed to getkey will be interpreted as a
successful match against it's list of characters.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Type "getkey -c 5 d" and wait.
Actual Results: You get garbage characters, repeated 5 times, followed by a
Expected Results: It should have waited 5 seconds for the d key, then ended

source code fix, and enhancements (such as --help message)

Makefile for changed getkey
Also added popt library usage, to provide long aliases for options and help
messages. Made getkey fail if no list of characters is provided -- was that
last change a good idea? Maybe that last bit should be removed?
Created attachment 80704 [details]
Improved source code file -- removed memory leak, restored allowing no keys to be specified, so that any key being hit can be captured, as was the case before.
